A. After Sensation - refers to the abnormal persistence of a sensory perception, provoked by a stimulus even though the stimulus has ceased.

B. Allodynia - pain due to a non-noxious stimulus that does not normally provoke pain.

1. Mechanical Allodynia - refers to the abnormal perception of pain from usually non-painful mechanical stimulation.

2. Static Mechanical Allodynia - refers to pain obtained by applying a single stimulus such as light pressure to a defined area.

3. Dynamic Mechanical Allodynia - obtained by moving the stimulus such as a brush or cotton tip across the abnormal hypersensitive area.

4. Thermal Allodynia - refers to the abnormal sensation of pain from usually non-painful thermal stimulation such as cold or warmth.

C. Central Pain - pain initiated or caused by a primary lesion or dysfunction in the central nervous system (CNS).

D. Central Sensitization - the experience of pain evoked by the excitation of non-nociceptive neurons or of nerve fibers that normally relay non-painful sensations to the spinal cord. This result when non-nociceptive afferent neurons act on a sensitized CNS.

E. Dystonia - state of abnormal (hypo or hyper) tonicity in any of the tissues.

F. Hyperalgesia - refers to an exaggerated pain response from a usually painful stimulation.

G. Hyperemia - presence of increased blood in a part or organ.

H. Hyperesthesia (Positive Sensory Phenomenon) - includes allodynia, hyperalgesia, and hyperpathia. Elicited by light touch, pin-prick, cold, warm vibration, joint position sensation or two-point discrimination, which is perceived as increased or more.

I. Hyperpathia - refers to an abnormally painful and exaggerated reaction to stimulus, especially to a repetitive stimulus, in a patient who perceives the stimulus as less intense because of an increased threshold.

J. Hypoesthesia (also hypesthesia) - diminished sensitivity to stimulation.

K. Pain Behavior - the nonverbal actions (such as grimacing, groaning, limping, using visible pain relieving or support devices and requisition of pain medications, among others) that are outward manifestations of pain, and through which a person may communicate that pain is being experienced.

L. Sudomotor Changes - alteration in function of sweat glands; sweat output may increase or decrease due to changes in autonomic input to the gland.

M. Sympathetically Maintained Pain (SMP) - a pain that is maintained by sympathetic efferent innervations or by circulating catecholalmines.

N. Trophic Changes - tissue alterations due to interruption of nerve or blood supply; may include changes in hair growth and texture of skin.

O. Vasomotor Changes - alteration in regulation of dilation or constriction of blood vessels.
