Aftersensation Refers to the abnormal persistence of a sensory perception, provoked by a stimulus even though the stimulus has ceased.
Allodynia Pain due to a non-noxious stimulus that does not normally provoke pain.
Dynamic Mechanical Allodynia - Obtained by moving the stimulus such as a brush or cotton tip across the abnormal hypersensitive area.
Mechanical Allodynia - Refers to the abnormal perception of pain from usually non-painful mechanical stimulation.
Static Mechanical Allodynia - Refers to pain obtained by applying a single stimulus such as light pressure to a defined area.
Thermal Allodynia - Refers to the abnormal sensation of pain from usually non-painful thermal stimulation such as cold or warmth.
Analgesia Absence of pain in response to stimulation that would normally be painful.
Biopsychosocial A term that reflects the multiple facets of any clinical situation; namely, the biological, psychological, and social situation of the patient.
Central Pain Pain initiated or caused by a primary lesion or dysfunction in the central nervous system.
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 results when non-nociceptive afferent neurons act on a sensitized central nervous system (CNS).
Dysesthesia An abnormal sensation described by the patient as unpleasant. As with paresthesia, dysesthesia may be spontaneous or evoked by maneuvers on physical examination.
Hyperalgesia Refers to an exaggerated pain response from a usually painful stimulation.
Hyperesthesia (Positive Sensory Phenomena) 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.
Hyperpathia Refers to an abnormally painful and exaggerated reaction to stimulus, especially to a repetitive stimulus.
Hypoalgesia Diminished pain perception in response to a normally painful stimulus.
Hypoesthesia (Negative Sensory Phenomena) Refers to a stimulus such as light touch, pin prick, cold, point position sensation, two-point discrimination, or sensory neglect which is perceived as decreased.
Malingering Intentional feigning of illness or disability in order to escape work or gain compensation.
Myofascial Pain A regional pain characterized by tender points in taut bands of muscle that produce pain in a characteristic reference zone.
Myofascial Trigger Point A physical sign in a muscle which includes a) exquisite tenderness in a taut muscle band; and b) referred pain elicited by mechanical stimulation of the trigger point. The following findings may be associated with myofascial trigger points:
Neuralgia Pain in the distribution of a nerve or nerves.
Neuritis Inflammation of a nerve or nerves.
Neurogenic Pain Pain initiated or caused by a primary lesion, dysfunction, or transitory perturbation in the peripheral or central nervous system.
Neuropathic Pain Pain due to an injured or dysfunctional central or peripheral nervous system.
Neuropathy A disturbance of function or pathological change in a nerve: in one nerve, mononeuropathy; in several nerves, mononeuropathy multiplex; if diffuse and bilateral, polyneuropathy.
Nociceptor A receptor preferentially sensitive to a noxious stimulus or to a stimulus which would become noxious if prolonged.
Pain Behavior The non-verbal 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.
Pain Threshold The smallest stimulus perceived by a subject as painful.
Paresthesia An abnormal sensation that is not described as pain. It can be either a spontaneous sensation (such as pins and needles) or a sensation evoked from non-painful or painful stimulation, such as light touch, thermal, or pinprick stimulus on physical examination.
Peripheral Neurogenic Pain Pain initiated or caused by a primary lesion or dysfunction or transitory perturbation in the peripheral nervous system.
Peripheral Neuropathic Pain Pain initiated or caused by a primary lesion or dysfunction in the peripheral nervous system.
Summation Refers to abnormally painful sensation to a repeated stimulus although the actual stimulus remains constant. The patient describes the pain as growing and growing as the same intensity stimulus continues.
Sympathetically Maintained Pain (SMP) A pain that is maintained by sympathetic efferent innervations or by circulating catecholamines.
Tender Points Tenderness on palpation at a tendon insertion, muscle belly or over bone. Palpation should be done with the thumb or forefinger, applying pressure approximately equal to a force of 4 kilograms (blanching of the entire nail bed).
