A. Initial Treatment Recommendations. Vascular cases will require surgical management and thus are not appropriate candidates for initial non-operative therapy. Cases of "non-specific" (also called disputed) TOS are treated conservatively first for a minimum of three months. Patients undergoing therapeutic procedures may return to modified or restricted duty during their rehabilitation, at the earliest appropriate time. Cessation and/or review of treatment modalities should be undertaken when no further significant subjective or objective improvement in the patient's condition is noted. Most literature of conservative therapy for TOS suggest benefit for patients with non-specific TOS. Non-surgical patients may be less likely to lose as much time from work as surgical patients. Initial treatment for TOS patients without indications for early surgery should include, patient education, jobsite alterations (especially if job activities are related to symptoms), neuromuscular education to emphasis proper breathing techniques and posture, nerve gliding and core body therapeutic exercise.

B. Postural risk factors should be identified. Awkward postures of overhead reach, hyperextension or rotation of the neck, shoulder drooped or forward-flexed and head-chin forward postures should be eliminated. Proper breathing techniques are also part of the treatment plan.

C. Therapy is primarily a daily self-managed home program developed and supervised by an appropriately trained professional. Nerve gliding and upper extremity stretching usually involves the following muscle groups: scalene, pectoralis minor, trapezius and levator scapulae. Endurance or strengthening of the upper extremities early in the course of therapy is not recommended, as this may exacerbate cervical or upper extremity symptoms.

D. Jobsite evaluation should be done early in all non-traumatic cases and should be performed by a qualified individual in all cases of suspected occupational TOS. Postural risk factors discussed above should be considered when making jobsite changes. Unless combined with one of the above postures, repetition alone is not a risk factor. Work activities need to be modified early in treatment to avoid further exposure to risk factors.

1. Acupuncture is an accepted and widely used procedure for the relief of pain and inflammation and there is some scientific evidence to support its use. The exact mode of action is only partially understood. Western medicine literature suggests that acupuncture stimulates the nervous system at the level of the brain, promotes deep relaxation, and affects the release of neurotransmitters. Acupuncture is commonly used as an alternative or in addition to traditional Western pharmaceuticals. While it is commonly used when pain medication is reduced or not tolerated, it may be used as an adjunct to physical rehabilitation and/or surgical intervention to hasten the return of functional activity. Acupuncture should be performed by licensed practitioners.
a. Acupuncture is the insertion and removal of filiform needles to stimulate acupoints (acupuncture points). Needles may be inserted, manipulated and retained for a period of time. Acupuncture can be used to reduce pain, reduce inflammation, increase blood flow, increase range of motion, decrease the side effect of medication-induced nausea, promote relaxation in an anxious patient, and reduce muscle spasm.
i. Indications include joint pain, joint stiffness, soft tissue pain and inflammation, paresthesia, post-surgical pain relief, muscle spasm, and scar tissue pain.

b. Acupuncture with electrical stimulation is the use of electrical current (micro-amperage or milli-amperage) on the needles at the acupuncture site. It is used to increase effectiveness of the needles by continuous stimulation of the acupoint. Physiological effects (depending on location and settings) can include endorphin release for pain relief, reduction of inflammation, increased blood circulation, analgesia through interruption of pain stimulus, and muscle relaxation.
i. It is indicated to treat chronic pain conditions, radiating pain along a nerve pathway, muscle spasm, inflammation, scar tissue pain, and pain located in multiple sites.

c. Total time frames for acupuncture and acupuncture with electrical stimulation time frames are not meant to be applied to each of the above sections separately. The time frames are to be applied to all acupuncture treatments regardless of the type or combination of therapies being provided.
i. Time to Produce Effect-three to six treatments.

ii. Frequency-one to three times per week.

iii. Optimum Duration-one to two months.

iv. Maximum Duration-14 treatments.
(a). Any of the above acupuncture treatments may extend longer if objective functional gains can be documented or when symptomatic benefits facilitate progression in the patient's treatment program. Treatment beyond 14 treatments must be documented with respect to need and ability to facilitate positive symptomatic or functional gains. Such care should be re-evaluated and documented with each series of treatments.

d. Other Acupuncture Modalities. Acupuncture treatment is based on individual patient needs and therefore treatment may include a combination of procedures to enhance treatment effect. Other procedures may include the use of heat, soft tissue manipulation/massage, and exercise. Refer to Active Therapy (Therapeutic Exercise) and, Passive Therapy sections (Massage and Superficial Heat and Cold Therapy) for a description of these adjunctive acupuncture modalities and time frames.

2. Biofeedback is a form of behavioral medicine that helps patients learn self-awareness and self-regulation skills for the purpose of gaining greater control of their physiology, such as muscle activity, brain waves, and measures of autonomic nervous system activity. Electronic instrumentation is used to monitor the targeted physiology and then displayed or fed back to the patient visually, auditorily, or tactilely, with coaching by a biofeedback specialist. Biofeedback is provided by clinicians certified in biofeedback and/or who have documented specialized education, advanced training, or direct or supervised experience qualifying them to provide the specialized treatment needed (e.g., surface EMG, EEG, or other).
a. Treatment is individualized to the patient's work-related diagnosis and needs. Home practice of skills is required for mastery and may be facilitated by the use of home training tapes. The ultimate goal in biofeedback treatment is normalizing the physiology to the pre-injury status to the extent possible and involves transfer of learned skills to the workplace and daily life. Candidates for biofeedback therapy or training must be motivated to learn and practice biofeedback and self-regulation techniques.

b. Indications for biofeedback include individuals who are suffering from musculoskeletal injury where muscle dysfunction or other physiological indicators of excessive or prolonged stress response affects and/or delays recovery. Other applications include training to improve self-management of emotional stress/pain responses such as anxiety, depression, anger, sleep disturbance, and other central and autonomic nervous system imbalances. Biofeedback is often utilized along with other treatment modalities.
i. Time to Produce Effect-three to four sessions.

ii. Frequency-one to two times per week.

iii. Optimum Duration-five to six sessions.

iv. Maximum Duration: 10 to 12 sessions. Treatment beyond 12 sessions must be documented with respect to need, expectation, and ability to facilitate positive symptomatic or functional gains.

3. Injections-Therapeutic
a. Scalene blocks have no therapeutic role in the treatment of TOS.

b. Trigger point injections, although generally accepted, are not routinely used in cases of TOS. However, it is not unusual to find myofascial trigger points associated with TOS pathology, which may require injections.
i. Description. Trigger point treatment can consist of dry needling or injection of local anesthetic with or without corticosteroid into highly localized, extremely sensitive bands of skeletal muscle fibers that produce local and referred pain when activated. Medication is injected in a four-quadrant manner in the area of maximum tenderness. Injection efficacy can be enhanced if injections are immediately followed by myofascial therapeutic interventions, such as vapo-coolant spray and stretch, ischemic pressure massage (myotherapy), specific soft tissue mobilization and physical modalities. There is conflicting evidence regarding the benefit of trigger point injections. A truly blinded study comparing dry needle treatment of trigger points is not feasible. There is no evidence that injection of medications improves the results of trigger-point injections. Needling alone may account for some of the therapeutic response.

ii There is no indication for conscious sedation for patients receiving trigger point injections. The patient must be alert to help identify the site of the injection.

iii. Indications. Trigger point injections may be used to relieve myofascial pain and facilitate active therapy and stretching of the affected areas. They are to be used as an adjunctive treatment in combination with other treatment modalities such as functional restoration programs. Trigger point injections should be utilized primarily for the purpose of facilitating functional progress. Patients should continue with a therapeutic exercise program as tolerated throughout the time period they are undergoing intensive myofascial interventions. Myofascial pain is often associated with other underlying structural problems and any abnormalities need to be ruled out prior to injection.

iv. Trigger point injections are indicated in those patients where well circumscribed trigger points have been consistently observed, demonstrating a local twitch response, characteristic radiation of pain pattern and local autonomic reaction, such as persistent hyperemia following palpation. Generally, these injections are not necessary unless consistently observed trigger points are not responding to specific, noninvasive, myofascial interventions within approximately a six-week time frame.

v. Complications. Potential but rare complications of trigger point injections include infection, pneumothorax, anaphylaxis, neurapraxia, and neuropathy. If corticosteroids are injected in addition to local anesthetic, there is a risk of local myopathy developing. Severe pain on injection suggests the possibility of an intraneural injection, and the needle should be immediately repositioned.
(a). Time to Produce Effect-local anesthetic, 30 minutes; no anesthesia, 24 to 48 hours.

(b). Frequency-weekly, suggest no more than four injection sites per session per week to avoid significant post-injection soreness.

(c). Optimal Duration-four weeks.

(d). Maximum Duration-eight weeks. Occasional patients may require two to four repetitions of trigger point injection series over a one to two year period.

4. Medications:
a. Thrombolytic agents will be required for some vascular TOS conditions.

b. Medication use is appropriate for pain control in TOS. A thorough medication history, including use of alternative and over the counter medications, should be performed at the time of the initial visit and updated periodically.

c. Acetaminophen is an effective and safe initial analgesic. Nonsteroidal anti-inflammatory drugs (NSAIDs) are useful in the treatment of inflammation, and for pain control. Pain is subjective in nature and should be evaluated using a scale to rate effectiveness of the analgesic in terms of functional gain. Other medications, including antidepressants and anti-convulsants, may be useful in selected patients with neuropathic and/or chronic pain (Refer to the OWCA's Chronic Pain Guidelines). Narcotics are rarely indicated for treatment of TOS, and they should be primarily reserved for the treatment of acute severe pain for a limited time on a case-by-case basis. Topical agents may be beneficial in the management of localized upper extremity pain.

d. The use of a patient completed pain drawing, Visual Analog Scale (VAS), is highly recommended to help providers track progress. Functional objective goals should be monitored regularly to determine the effectiveness of treatment. The patient should be advised regarding the interaction with prescription and over-the-counter herbal products.

e. The following medications are listed in alphabetical order.
i. Acetaminophen is an effective analgesic with antipyretic but not anti-inflammatory activity. Acetaminophen is generally well tolerated, causes little or no gastrointestinal irritation and is not associated with ulcer formation. Acetaminophen has been associated with liver toxicity in overdose situations or in chronic alcohol use. Patients may not realize that many over-the-counter preparations may contain acetaminophen. The total daily dose of acetaminophen is recommended not to exceed 2250 mg per 24 hour period, from all sources, including narcotic-acetaminophen combination preparations.
(a). Optimal Duration-7 to 10 days.

(b). Maximum Duration-chronic use as indicated on a case-by-case basis. Use of this substance long-term for three days per week or greater may be associated with rebound pain upon cessation.

ii. Anticonvulsants. Although the mechanism of action of anticonvulsant drugs in neuropathic pain states remains to be fully defined, they appear to act as nonselective sodium channel blocking agents. A large variety of sodium channels are present in nervous tissue, and some of these are important mediators of nociception, as they are found primarily in unmyelinated fibers and their density increases following nerve injury. While the pharmacodynamic effects of the various anticonvulsant drugs are similar, the pharmacokinetic effects differ significantly. Carbamazepine has important effects as an inducer of hepatic enzymes and may influence the metabolism of other drugs enough to present problems in patients taking more than one drug. Gabapentin and oxcarbazepine, by contrast, are relatively non-significant enzyme inducers, creating fewer drug interactions. Because anticonvulsant drugs may have more problematic side-effect profiles, their use should usually be deferred until antidepressant drugs have failed to relieve pain.
(a). Gabapentin (Neurontin)
(i). Description-structurally related to gamma aminobutyric acid (GABA) but does not interact with GABA receptors.

(ii). Indications-neuropathic pain.

(iii). Relative Contraindications-renal insufficiency.

iv. Dosing and Time to Therapeutic Effect-dosage may be increased over several days.

v. Major Side Effects-confusion, sedation.

vi. Drug Interactions-oral contraceptives, cimetidine, antacids.

vii. Recommended Laboratory Monitoring-renal function.

iii. Antidepressants are classified into a number of categories based on their chemical structure and their effects on neurotransmitter systems. Their effects on depression are attributed to their actions on disposition of norepinephrine and serotonin at the level of the synapse; although these synaptic actions are immediate, the symptomatic response in depression is delayed by several weeks. When used for chronic pain, the effects may in part arise from treatment of underlying depression, but may also involve additional neuromodulatory effects on endogenous opioid systems, raising pain thresholds at the level of the spinal cord.
(a). Pain responses may occur at lower drug doses with shorter times to symptomatic response than are observed when the same compounds are used in the treatment of mood disorders. Neuropathic pain, diabetic neuropathy, post-herpetic neuralgia, and cancer-related pain may respond to antidepressant doses low enough to avoid adverse effects that often complicate the treatment of depression.
(i). Tricyclics (e.g., amitryptiline [Elavil], nortriptyline [Pamelor, Aventyl], doxepin [Sinequan, Adapin])
[a]. Description-serotonergics, typically tricyclic antidepressants (TCAs), are utilized for their serotonergic properties as increasing CNS serotonergic tone can help decrease pain perception in non-antidepressant dosages. Amitriptyline is known for its ability to repair Stage 4 sleep architecture, a frequent problem found in chronic pain patients and to treat depression, frequently associated with chronic pain.

[b]. Indications-chronic musculoskeletal and/or neuropathic pain, insomnia. Second line drug treatment for depression.

[c]. Major Contraindications-cardiac disease or dysrhythmia, glaucoma, prostatic hypertrophy, seizures, suicide risk.

[d]. Dosing and Time to Therapeutic Effect-varies by specific tricyclic. Low dosages are commonly used for chronic pain and/or insomnia.

[e]. Major Side Effects-anticholinergic side effects including, but not limited to, dry mouth, sedation, orthostatic hypotension, cardiac arrhythmia, weight gain.

[f]. Drug Interactions-tramadol (may cause seizures), clonidine, cimetidine, sympathomimetics, valproic acid, warfarin, carbamazepine, bupropion, anticholinergics, quinolones.

[g]. Recommended Laboratory Monitoring-renal and hepatic function. Electrocardiogram (EKG) for those on high dosages or with cardiac risk.

iv. Minor tranquilizer/muscle relaxants are appropriate for muscle spasm, mild pain and sleep disorders.
(a). Optimum Duration-up to one week.

(b). Maximum Duration-four weeks.

v. Narcotics medications should be prescribed with strict time, quantity and duration guidelines, and with definitive cessation parameters. Adverse effects include respiratory depression, impaired alertness, and the development of physical and psychological dependence.
(a). Optimum Duration-up to seven days.

(b). Maximum Duration-two weeks. Use beyond two weeks is acceptable in appropriate cases, such as patients requiring complex surgical treatment.

vi. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) are useful for pain and inflammation. In mild cases, they may be the only drugs required for analgesia. There are several classes of NSAIDs, and the response of the individual injured worker to a specific medication is unpredictable. For this reason, a range of NSAIDs may be tried in each case with the most effective preparation being continued. Patients should be closely monitored for adverse reactions. The US Food and Drug Administration advises that many NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Naproxen sodium does not appear to be associated with increased risk of vascular events. Administration of proton pump inhibitors, Histamine 2 Blockers, or prostaglandin analog misoprostol along with these NSAIDs may reduce the risk of duodenal and gastric ulceration but do not impact possible cardiovascular complications. Due to the cross-reactivity between aspirin and NSAIDs, NSAIDs should not be used in aspirin-sensitive patients, and should be used with caution in all asthma patients. NSAIDs are associated with abnormal renal function, including renal failure, as well as, abnormal liver function. Certain NSAIDs may have interactions with various other medications. Individuals may have adverse events not listed above. Intervals for metabolic screening are dependent upon the patient's age, general health status and should be within parameters listed for each specific medication. Complete Blood Count (CBC), and liver and renal function should be monitored at least every six months in patients on chronic NSAIDs and initially when indicated.
(a). Non-selective Nonsteroidal Anti-Inflammatory Drugs
(i). Includes NSAIDs and acetylsalicylic acid (aspirin). Serious GI toxicity, such as bleeding, perforation, and ulceration can occur at any time, with or without warning symptoms in patients treated with traditional NSAIDs. Physicians should inform patients about the signs and/or symptoms of serious gastrointestinal toxicity and what steps to take if they occur. Anaphylactoid reactions may occur in patients taking NSAIDs. NSAIDs may interfere with platelet function. Fluid retention and edema have been observed in some patients taking NSAIDs.
[a]. Optimal Duration-one week.

[b]. Maximum Duration-one year. Use of these substances long-term (three days per week or greater) is associated with rebound pain upon cessation.

(b). Selective Cyclo-oxygenase-2 (COX-2) Inhibitors
(i). COX-2 inhibitors are more recent NSAIDs and differ in adverse side effect profiles from the traditional NSAIDs. The major advantages of selective COX-2 inhibitors over traditional NSAIDs are that they have less gastrointestinal toxicity and no platelet effects. COX-2 inhibitors can worsen renal function in patients with renal insufficiency, thus renal function may need monitoring.

(ii). COX-2 inhibitors should not be first-line for low risk patients who will be using an NSAID short-term but are indicated in select patients for whom traditional NSAIDs are not tolerated. Serious upper GI adverse events can occur even in asymptomatic patients. Patients at high risk for GI bleed include those who use alcohol, smoke, are older than 65, take corticosteroids or anti-coagulants, or have a longer duration of therapy. Celecoxib is contraindicated in sulfonamide allergic patients.
[a]. Optimal Duration-7 to 10 days.

[b]. Maximum Duration-chronic use is appropriate in individual cases. Use of these substances long-term (three days per week or greater) is associated with rebound pain upon cessation.

5. Occupational Rehabilitation Programs
a. Non-Interdisciplinary. These generally accepted programs are work-related, outcome-focused, individualized treatment programs. Objectives of the program include, but are not limited to, improvement of cardiopulmonary and neuromusculoskeletal functions (strength, endurance, movement, flexibility, stability, and motor control functions), patient education, and symptom relief. The goal is for patients to gain full or optimal function and return to work. The service may include the time-limited use of passive modalities with progression to achieve treatment and/or simulated/real work. These programs are frequently necessary for patients who must return to physically demanding job duties or whose injury requires prolonged rehabilitation and therapy spanning several months.
i. Work Conditioning. These programs are usually initiated once reconditioning has been completed but may be offered at any time throughout the recovery phase. It should be initiated when imminent return of a patient to modified or full duty is not an option, but the prognosis for returning the patient to work at completion of the program is at least fair to good.
(a). Length of Visit-one to two hours per day.

(b). Frequency-two to five visits per week.

(c). Optimum Duration-two to four weeks.

(d). Maximum Duration-six weeks. Participation in a program beyond six weeks must be documented with respect to need and the ability to facilitate positive symptomatic or functional gains.

ii. Work Simulation. Work Simulation is a program where an individual completes specific work-related tasks for a particular job and return-to-work. Use of this program is appropriate when modified duty can only be partially accommodated in the work place, when modified duty in the work place is unavailable, or when the patient requires more structured supervision. The need for work place simulation should be based upon the results of a functional capacity evaluation and/or jobsite analysis.
(a). Length of Visit-two to six hours per day.

(b). Frequency-two to five visits per week.

(c). Optimum Duration-two to four weeks.

(d). Maximum Duration-six weeks. Participation in a program beyond six weeks must be documented with respect to need and the ability to facilitate positive symptomatic or functional gains.

b. Interdisciplinary programs are well-established treatment for patients with sub-acute and functionally impairing cervical spine pain. They are characterized by a variety of disciplines that participate in the assessment, planning, and/or implementation of an injured workers program with the goal for patients to gain full or optimal function and return to work. There should be close interaction and integration among the disciplines to ensure that all members of the team interact to achieve team goals. Programs should include cognitive-behavioral therapy as there is good evidence for its effectiveness in patients with chronic low back pain and it is probably effective in cervical spine pain. These programs are for patients with greater levels of disability, dysfunction, deconditioning and psychological involvement. For patients with chronic pain, refer to the Chronic Pain Disorder Medical Treatment Guidelines.
i. Work Hardening. Work hardening is an interdisciplinary program addressing a patient's employability and return to work. It includes a progressive increase in the number of hours per day that a patient completes work simulation tasks until the patient can tolerate a full workday. This is accomplished by addressing the medical, psychological, behavioral, physical, functional, and vocational components of employability and return-to-work.
(a). This can include a highly structured program involving a team approach or can involve any of the components thereof. The interdisciplinary team should, at a minimum, be comprised of a qualified medical director who is board certified with documented training in occupational rehabilitation; team physicians having experience in occupational rehabilitation; occupational therapy; physical therapy; case manager; and psychologist. As appropriate, the team may also include: chiropractor, RN, vocational specialist or certified biofeedback therapist.
(i). Length of Visit-up to eight hours/day.

(ii). Frequency-two to five visits per week.

(iii). Optimal Duration-two to four weeks.

(iv). Maximum Duration-six weeks. Participation in a program beyond six weeks must be documented with respect to need and the ability to facilitate positive symptomatic or functional gains.

6. Patient Education. No treatment plan is complete without addressing issues of individual and/or group patient education as a means of prolonging the beneficial effects of treatment, as well as facilitating self-management of symptoms and injury prevention. The patient should be encouraged to take an active role in the establishment of functional outcome goals. They should be educated on their specific injury, assessment findings, and plan of treatment. Instruction on breathing technique, proper body mechanics and posture, positions to avoid, self-care for exacerbation of symptoms, sleep postures, and home exercise should also be addressed. Patients with TOS may find that sleeping on the affected side, with the arms overhead or prone with head to one side can increase symptoms and should be avoided. Cervical roll pillows that do not result in overextension may be useful.
a. Time to Produce Effect-varies with individual patient.

b. Frequency-should occur at each visit.

7. Personality/Psychosocial/Psychiatric/Psychological Intervention. Psychosocial treatment is generally accepted, widely used, and well-established intervention. This group of therapeutic and diagnostic modalities includes, but is not limited to, individual counseling, group therapy, stress management, psychosocial crises intervention, hypnosis and meditation. Any evaluation or diagnostic workup should clarify and distinguish between pre-existing versus aggravated versus purely causative psychological conditions. Psychosocial intervention is recommended as an important component in the total management program that should be implemented as soon as the problem is identified. This can be used alone or in conjunction with other treatment modalities. Providers treating patients with chronic pain should refer to the OWCA's Chronic Pain Disorder Medical Treatment Guidelines.
a. Time to Produce Effect-two to four weeks.

b. Frequency-one to three times weekly for the first four weeks (excluding hospitalization, if required), decreasing to one to two times per week for the second month. Thereafter, two to four times monthly.

c. Optimum Duration-six weeks to three months.

d. Maximum Duration-3 to 12 months. Counseling is not intended to delay but to enhance functional recovery. For select patients, longer supervised treatment may be required and if further counseling beyond 3 months is indicated, extensive documentation addressing which pertinent issues are pre-existing versus aggravated versus causative, as well as projecting a realistic functional prognosis, should be provided by the authorized treating provider every 4 to 6 weeks during treatment.

8. Return-to-Work. Early return-to-work should be a prime goal in treating occupational injuries given the poor return-to-work prognosis for an injured worker who has been out of work for more than six months. It is imperative that the patient be educated regarding the benefits of return-to-work, work restrictions, and follow-up care if problems arise. When attempting to return a patient to work after a specific injury, clear objective restrictions of activity level should be made. An accurate job description with detailed physical duty restrictions may be necessary to assist the physician in making return-to-work recommendations. This may require a jobsite evaluation.
a. Employers should be prepared to offer transitional work. This may consist of temporary work in a less demanding position, return to the regular job with restrictions, or gradual return to the regular job. Company policies which encourage return-to-work with positive communication are most likely to have decreased worker disability.

b. Return-to-Work-any work or duty that the patient is able to perform safely. It may not be the patient's regular work. Due to the large spectrum of injuries of varying severity and varying physical demands in the work place, it is not possible to make specific return-to-work guidelines for each injury. Therefore, the OWCA recommends the following:
i. Establishment of a Return-to-Work Status. Ascertaining a return-to-work status is part of medical care, should be included in the treatment and rehabilitation plan, and addressed at every visit. A description of daily activity limitations is part of any treatment plan and should be the basis for restriction of work activities. In most non-surgical cases, the patient should be able to return-to-work in some capacity or in an alternate position consistent with medical treatment within several days unless there are extenuating circumstances. Injuries requiring more than two weeks off work should be thoroughly documented.

ii. Establishment of Activity Level Restrictions. Communication is essential between the patient, employer and provider to determine appropriate restrictions and return-to-work dates. It is the responsibility of the physician to provide clear concise restrictions, and it the employer's responsibility to determine if temporary duties can be provided within the restrictions. For treatment of TOS injuries, the following should be addressed when describing the patient's activity level:
(a). activities such as overhead motion, lifting, abduction;

(b). static neck and shoulder positions with regard to duration and frequency;

(c). restriction of cervical hyperextension;

(d). use of adaptive devices or equipment for proper ergonomics and to enhance capacities;

(e). maximum Lifting limits with reference to the frequency of the lifting and/or the object height level;

(f). maximum limits for pushing, pulling, with limits on bending and twisting at the waist as necessary; and

(g). testrictions on shoulder drooped' or head forward' positions.

iii. Compliance with Activity Restrictions. In some cases, compliance with restriction of activity levels may require a complete jobsite evaluation, a functional capacity evaluation (FCE), or other special testing. Refer to the special tests section of this guideline.

9. Therapy-active. The following active therapies are widely used and accepted methods of care for a variety of work-related injuries. They are based on the philosophy that therapeutic exercise and/or activity are beneficial for restoring flexibility, strength, endurance, function, range of motion, and can alleviate discomfort. Active therapy requires physical effort by the individual to complete a specific exercise or task. This form of therapy requires supervision from a therapist or medical provider such as verbal, visual, and/or tactile instruction(s). At times, the provider may help stabilize the patient or guide the movement pattern but the energy required to complete the task is predominately executed by the patient.
a. Patients should be instructed to continue active therapies at home as an extension of the treatment process in order to maintain improvement levels. Follow-up visits to reinforce and monitor progress and proper technique are recommended. Home exercise can include exercise with or without mechanical assistance or resistance and functional activities with assistive devices.

b. The use of a patient completed pain drawing, Visual Analog Scale (VAS), is highly recommended to help providers track progress. Functional objective goals should be monitored and documented regularly to determine the effectiveness of treatment.

c. The following active therapies are listed in alphabetical order.
i. Activities of daily living (ADL) are well-established interventions which involve instruction, active-assisted training, and/or adaptation of activities or equipment to improve a person's capacity in normal daily activities such as self-care, work re-integration training, homemaking, and driving.
(a). Time to Produce Effect-four to five treatments.

(b). Frequency-three to five times per week.

(c). Optimum Duration-four to six weeks.

(d). Maximum Duration-six weeks.

ii. Aquatic therapy is a well-accepted treatment which consists of the therapeutic use of aquatic immersion for therapeutic exercise to promote range-of-motion, core stabilization, endurance, flexibility, strengthening, body mechanics, and pain management. Aquatic therapy includes the implementation of active therapeutic procedures in a swimming or therapeutic pool. The water provides a buoyancy force that lessens the amount of force gravity applies to the body. The decreased gravity effect allows the patient to have a mechanical advantage and more likely have a successful trial of therapeutic exercise. Literature has shown that the muscle recruitment for aquatic therapy versus similar nonaquatic motions is significantly less. Because there is always a risk of recurrent or additional damage to the muscle tendon unit after a surgical repair, aquatic therapy may be preferred by surgeons to gain early return of range of motion. In some cases the patient will be able to do the exercises unsupervised after the initial supervised session. Parks and recreation contacts may be used to develop less expensive facilities for patients. Indications include:
(a). postoperative therapy as ordered by the surgeon; or Intolerance for active land-based or full-weight bearing therapeutic procedures; or

(b). symptoms that are exacerbated in a dry environment; and

(c). willingness to follow through with the therapy on a regular basis.
(i). The pool should be large enough to allow full extremity range of motion and fully erect posture. Aquatic vests, belts, snorkels, and other devices may be used to provide stability, balance, buoyancy, and resistance.
[a]. Time to Produce Effect-four to five treatments.

[b]. Frequency-three to five times per week.

[c]. Optimum Duration: Four to six weeks.

[d]. Maximum Duration: eight weeks

(ii). A self-directed program is recommended after the supervised aquatics program has been established, or, alternatively a transition to a self-directed dry environment exercise program.

(iii). Functional activities are well-established interventions which involve the use of therapeutic activity to enhance mobility, body mechanics, employability, coordination, balance, and sensory motor integration.
[a]. Time to Produce Effect-four to five treatments.

[b]. Frequency-three to five times per week.

[c]. Optimum Duration-four to six weeks.

[d]. Maximum Duration-six weeks.

(iv). Nerve Gliding is an accepted therapy for TOS. Nerve Gliding exercises consist of a series of gentle movements of the neck, shoulder and arm that produce longitudinal movement along the length of the nerves of the upper extremity. These exercises are based on the principle that the tissues of the peripheral nervous system are designed for movement, and glide (excursion) of nerves may have an effect on neurophysiology through alterations in vascular and axoplasmic flow. Biomechanical principles have been more thoroughly studied than clinical outcomes. The exercises should be done by the patient after proper instruction and monitoring by the therapist.
[a]. Time to Produce Effect-two to four weeks.

[b]. Frequency-up to five times per day by patient (patient-initiated).

[c]. Optimum Duration-four to six sessions.

[d]. Maximum Duration-six to eight sessions.

(v). Neuromuscular re-education is a generally accepted treatment. Neuromuscular re-education is the skilled application of exercise with manual, mechanical, or electrical facilitation to enhance strength; movement patterns; neuromuscular response; proprioception, kinesthetic sense, coordination; education of movement, balance and posture. Indications include the need to promote neuromuscular responses through carefully timed proprioceptive stimuli to elicit and improve motor activity in patterns similar to normal neurologically developed sequences, and improve neuromotor response with independent
[a]. Time to Produce Effect-two to six treatments.

[b]. Frequency-three times per week.

[c]. Optimum Duration-four to eight weeks.

[d]. Maximum Duration-eight weeks.

(vi). Therapeutic exercise is a generally well-accepted treatment. Therapeutic exercise with or without mechanical assistance or resistance, may include isoinertial, isotonic, isometric and isokinetic types of exercises. The exact type of program and length of therapy should be determined by the treating physician with the physical or occupational therapist. In most cases the therapist instructs the patient in a supervised clinic and home program to increase motion and subsequently increase strength. Usually, isometrics are performed initially, progressing to isotonic exercises as tolerated.
[a]. time to produce effect: two to six treatments;

[b]. frequency: two to three times per week;

[c]. optimum duration: 16 to 24 sessions;

[d]. maximum duration: 36 sessions. Additional visits may be necessary in cases of re-injury, interrupted continuity of care, exacerbation of symptoms, and in those patients with comorbidities. Functional gains including increased range of motion must be demonstrated to justify continuing treatment.

10. Therapy-Passive. The following passive therapies and modalities are generally accepted methods of care for a variety of work-related injuries. Passive therapy includes those treatment modalities that do not require energy expenditure on the part of the patient. They are principally effective during the early phases of treatment and are directed at controlling symptoms such as pain, inflammation and swelling and to improve the rate of healing soft tissue injuries. They should be use adjunctively with active therapies such as postural stabilization and exercise programs to help control swelling, pain and inflammation during the rehabilitation process. Please refer to, General Guidelines Principles, Active Interventions. Passive therapies may be used intermittently as a therapist deems appropriate or regularly if there are specific goals with objectively measured functional improvements during treatment.
a. On occasion, specific diagnoses and post-surgical conditions may warrant durations of treatment beyond those listed as "maximum." Factors such as exacerbation of symptoms, re-injury, interrupted continuity of care, and comorbidities may also extend durations of care. Specific goals with objectively measured functional improvement during treatment must be cited to justify extended durations of care. It is recommended that, if no functional gain is observed after the number of treatments under "time to produce effect" has been completed, alternative treatment interventions, further diagnostic studies, or further consultations should be pursued.

b. The following passive therapies and modalities are listed in alphabetical order.
i. Electrical stimulation (unattended) is an accepted treatment. Once applied, electrical stimulation (unattended) requires minimal on-site supervision by the physical therapists, occupational therapist or other provider. Indications include pain, inflammation, muscle spasm, atrophy, decreased circulation, and the need for osteogenic stimulation. A home unit should be purchased if treatment is effective and frequent use is recommended.
(a). Time to Produce Effect-two to four treatments.

(b). Frequency-varies, depending upon indication, between two to three times/day to one time/week;

(c). Optimum Duration-one to three months;

(d). Maximum Duration-three months.

ii. Iontophoresis is an accepted treatment which consists of the transfer of medication, including, but not limited to, steroidal anti-inflammatories and anesthetics, through the use of electrical stimulation. Indications include pain (lidocaine), inflammation (hydrocortisone, salicylate), edema (mecholyl, hyaluronidase, and salicylate), ischemia (magnesium, mecholyl, and iodine), muscle spasm (magnesium, calcium), calcifying deposits (acetate), scars, and keloids (sodium chloride, iodine, acetate).
(a). Time to Produce Effect-one to four treatments.

(b). Frequency-three times per week with at least 48 hours between treatments.

(c). Optimum Duration-8 to 10 treatments.

(d). Maximum Duration-10 treatments.

iii. Manipulation is a generally accepted treatment. Manipulative treatment (not therapy) is defined as the therapeutic application of manually guided forces by an operator to improve physiologic function and/or support homeostasis that has been altered by the injury or occupational disease, and has associated clinical significance.
(a). High velocity, low amplitude (HVLA) technique, chiropractic manipulation, osteopathic manipulation, muscle energy techniques, counter strain, and non-force techniques are all types of manipulative treatment. This may be applied by osteopathic physicians (D.O.), chiropractors (D.C.), properly trained physical therapists (P.T.), properly trained occupational therapists (O.T.), or properly trained medical physicians. Under these different types of manipulation exist many subsets of different techniques that can be described as direct- a forceful engagement of a restrictive/pathologic barrier; indirect- a gentle/non-forceful disengagement of a restrictive/pathologic barrier; the patient actively assisting in the treatment; and the patient relaxing, allowing the practitioner to move the body tissues. When the proper diagnosis is made and coupled with the appropriate technique, manipulation has no contraindications and can be applied to all tissues of the body. Pre-treatment assessment should be performed as part of each manipulative treatment visit to ensure that the correct diagnosis and correct treatment is employed.
(i). Time to Produce Effect for all Types of Manipulative Treatment-one to six treatments.

(ii). Frequency-up to three times per week for the first three weeks as indicated by the severity of involvement and the desired effect.

(iii). Optimum Duration-10 treatments.

(iv). Maximum Duration-12 treatments. Additional visits may be necessary in cases of re-injury, interrupted continuity of care, exacerbation of symptoms, and in those patients with comorbidities. Functional gains including increased range of motion must be demonstrated to justify continuing treatment.

iv. Massage, manual or mechanical, is a generally well-accepted treatment. Massage is manipulation of soft tissue with broad ranging relaxation and circulatory benefits. This may include stimulation of acupuncture points and acupuncture channels (acupressure), application of suction cups and techniques that include pressing, lifting, rubbing, pinching of soft tissues by, or with the practitioner's hands. Indications include edema (peripheral or hard and non-pliable edema), muscle spasm, adhesions, the need to improve peripheral circulation and range of motion, or to increase muscle relaxation and flexibility prior to exercise. In cases with edema, deep vein thrombosis should be ruled out prior to treatment.
(a). Time to Produce Effect-immediate.

(b). Frequency-one to two times per week.

(c). Optimum Duration-six weeks.

(d). Maximum Duration-two months.

v. Mobilization (joint) is a generally well-accepted treatment. Mobilization is passive movement, which may include passive range of motion performed in such a manner (particularly in relation to the speed of the movement) that it is, at all times, within the ability of the patient to prevent the movement if they so choose. It may include skilled manual joint tissue stretching. Indications include the need to improve joint play, improve intracapsular arthrokinematics, or reduce pain associated with tissue impingement.
(a). Time to Produce Effect-six to nine treatments.

(b). Frequency-three times per week.

(c). Optimum Duration-six weeks.

(d). Maximum Duration-two months.

vi. Mobilization (soft tissue) is a generally well-accepted treatment. Mobilization of soft tissue is the skilled application of muscle energy, strain/counter strain, myofascial release, manual trigger point release and manual therapy techniques designed to improve or normalize movement patterns through the reduction of soft tissue pain and restrictions. These can be interactive with the patient participating or can be with the patient relaxing and letting the practitioner move the body tissues. Indications include muscle spasm around a joint, trigger points, adhesions, and neural compression. Mobilization should be accompanied by active therapy.
(a). Time to Produce Effect-two to three weeks.

(b). Frequency-two to three times per week.

(c). Optimum Duration-four to six weeks.

(d). Maximum Duration-six weeks.

vii. Superficial heat and cold therapy is a generally accepted treatment. Superficial heat and cold therapies are thermal agents applied in various manners that lower or raise the body tissue temperature for the reduction of pain, inflammation, and/or effusion resulting from injury or induced by exercise. It may be used acutely with compression and elevation. Indications include acute pain, edema and hemorrhage, need to increase pain threshold, reduce muscle spasm and promote stretching/flexibility. Includes portable cryotherapy units and application of heat just above the surface of the skin at acupuncture points.
(a). Time to Produce Effect-immediate.

(b). Frequency-two to five times per week.

(c). Optimum Duration-three weeks as primary, or up to two months if used intermittently as an adjunct to other therapeutic procedures.

(d). Maximum Duration-two months.

viii. Transcutaneous electrical nerve stimulation (TENS) is a generally accepted treatment and should include at least one instructional session for proper application and use. Indications include muscle spasm, atrophy, and decreased circulation and pain control. Minimal TENS unit parameters should include pulse rate, pulse width and amplitude modulation. Consistent, measurable functional improvement must be documented prior to the purchase of a home unit.
(a). Time to Produce Effect-immediate.

(b). Frequency-variable.

(c). Optimum Duration-three sessions.

(d). Maximum Duration-three sessions. If beneficial, provide with home unit or purchase if effective.

ix. Ultrasound (including phonophoresis) is an accepted treatment and includes ultrasound with electrical stimulation and phonophoresis. Ultrasound uses sonic generators to deliver acoustic energy for therapeutic thermal and/or non-thermal soft tissue effects. Indications include scar tissue, adhesions, collagen fiber and muscle spasm, and the need to extend muscle tissue or accelerate the soft tissue healing.
(a). Ultrasound with electrical stimulation is concurrent delivery of electrical energy that involves a dispersive electrode placement. Indications include muscle spasm, scar tissue, pain modulation, and muscle facilitation.

(b). Phonophoresis is the transfer of medication to the target tissue to control inflammation and pain through the use of sonic generators. These topical medications include, but are not limited to, steroidal anti-inflammatory and anesthetics.
(i). Time to Produce Effect-6 to 15 treatments.

(ii). Frequency-3 times per week.

(iii). Optimum Duration-4 to 8 weeks.

(iv). Maximum Duration-2 months.

11. Vocational rehabilitation is a generally accepted intervention. Initiation of vocational rehabilitation requires adequate evaluation of patients for quantification highest functional level, motivation and achievement of maximum medical improvement. Vocational rehabilitation may be as simple as returning to the original job or as complicated as being retrained for a new occupation.
a. It may also be beneficial for full vocational rehabilitation to be started before MMI if it is evident that the injured worker will be unable to return to his/her previous occupation. A positive goal and direction may aid the patient in decreasing stress and depression, and promote optimum rehabilitation.
