Neuro Flashcards
Tics
a habitual spasmodic contraction of the muscles, most often in the face.
Dystonia
a state of abnormal muscle tone resulting in muscular spasm and abnormal posture, typically due to neurological disease or a side effect of drug therapy
Intention tremor
a trembling of a part of the body when attempting a precise movement, associated especially with disease of the cerebellum
myoclonus
spasmodic jerky contraction of groups of muscles
dystrophic gait
waddling gait, a gait characterized by exaggerated lateral trunk movements and hip elevations.
sensory ataxia
both a symptom and a sign in neurology. It is a form of ataxia (loss of coordination) caused not by cerebellar dysfunction but by loss of sensory input into the control of movement. (ataxia is the loss of full control of bodily movements)
asterixis
Asterixis (also called the flapping tremor, or liver flap) is a tremor of the hand when the wrist is extended, sometimes said to resemble a bird flapping its wings.
dyskinesia
abnormality or impairment of voluntary movement
chorea
a neurological disorder characterized by jerky involuntary movements affecting especially the shoulders, hips, and face
resting tremor
Resting tremor occurs when the muscle is relaxed, such as when the hands are resting on the lap. With this disorder, a person’s hands, arms, or legs may shake even when they are at rest. Often, the tremor only affects the hand or fingers.
oral-facial dyskinesias
Orofacial or tardive dyskinesias are involuntary repetitive movements of the mouth and face.
spastic hemiparesis
one half of the body is afflicted with weakness, but is not paralyzed.
steppage gait
Steppage gait (High stepping, Neuropathic gait) is a form of gait abnormality characterised by foot drop due to loss of dorsiflexion. The foot hangs with the toes pointing down, causing the toes to scrape the ground while walking, requiring someone to lift the leg higher than normal when walking.
antalgic gait
An antalgic gait is a gait that develops as a way to avoid pain while walking (antalgic = anti- + alge, “against pain”). It is a form of gait abnormality where the stance phase of gait is abnormally shortened relative to the swing phase. It can be a good indication of pain with weight-bearing.
apraxia
inability to perform particular purposive actions, as a result of brain damage.
