Loss of ability to recognize importance of sensory impressions
Agnosia
Loss of ability to express thoughts in writing
Agraphia
Loss of memory
Amnesia
Loss of pain sensation
Analgesia
Loss of power of expression by speech, writing, or signs; or loss of comprehension of spoken or written language
Aphasia
Loss of ability to perform purposeful movements in the absence of sensory or motor damage; eg. inability to use objects correctly
Apraxia
Inability to perform coordinated movements
Ataxia
Bizarre, slow, twisting, writhing movement, resembling a snake or worm
Athetosis
Sudden, rapid, jerky, purposeless movement involving limbs, trunk, or face
Chorea
Rapidly alternating involuntary contraction and relaxation of a muscle in response to sudden stretch
Clonus
State of profound unconsciousness from which person cannot be aroused
Coma
Collision or trauma causes violent shaking of brain, yielding behavioral changes but no changes on radiologic imaging
Concussion
Arms stiffly extended, adducted, internally rotated; legs stiffly extended, plantar-flexed
Decerebrate rigidity
Arms adducted and flexed, wrists and fingers flexed; legs extended, internally rotated, plantar-flexed
Decorticate rigidity
Imperfect articulation of speech due to problems of muscular control resulting from central or peripheral nervous system damage
Dysarthria
Impairment in speech consisting of lack of coordination and inability to arrange words in their proper order
Dysphasia
Disappearance of conditioned response
Extinction
Rapid continuous twitching of resting muscle without movement of limb
Fasciculation
Loss of muscle tone, limp
Flaccidity
Ability to “read” a number by having it traced on the skin
Graphesthesia
Loss of motor power (paralysis) on one side of the body, usually caused by a stroke; paralysis occurs on side opposite the lesion
Hemiplegia
Motor neuron in the peripheral nervous system with its nerve fiber extending out to the muscle and only its cell body in the central nervous system
Lower motor neuron
Rapid sudden jerk of a muscle
Myoclonus
Stiffness in cervical neck area
Nuchal rigidity
Back and forth oscillation of the eyes
Nystagmus
Prolonged arching of back, with head and heels bent backward, and meninges irritation
Opisthotonos
Decreased or loss of motor function due to problem with motor nerve or muscle fibers
Paralysis
Impairment or loss of motor and/or sensory function in the lower half of the body
Paraplegia
Abnormal sensation (burning, numbness, tingling, prickling, crawling skin sensation)
Paresthesia
Ability of the person to discriminate exactly where on the body the skin has been touched
Point localization
Sensory information concerning body movements and position of the body in space
Proprioception
Continuous resistance to stretching by a muscle due to abnormally increased tension with increased deep tendon reflexes
Spasticity
Ability to recognize objects by feeling their form, size, and weight while the eyes are closed
Stereognosis
Repetitive twitching of a muscle group at inappropriate times (eg. wink or grimace)
Tic
Involuntary contraction of opposing muscle groups resulting in rhythmic movement of one or more joints
Tremor
Ability to distinguish the separation of two simultaneous pinpricks on the skin
Two-point discrimination
Nerve located entirely within the central nervous system
Upper motor neuron
