Table 6.1 Flashcards
Involuntary oscillatory movement resulting from alternate contractions of opposing muscle groups
Tremor
Oscillatory movement during voluntary motion; increases as the limb nears target; diminished or absent at rest
Intention (Kinetic)
Exaggerated oscillatory movement of the body in standing posture or of a limb held against gravity
Postural (static)
Rhythmic oscillations of the head; axial involvement of the trunk
Titubation
Inability to initiate movement; associated with fixed postures
Akinesia
Slow, involuntary, writhing, twisting, “wormlike” movements; frequently greater involvement in distal UEs
Athetosis
Involuntary, rapid, irregular, jerky movements involving multiple joints; most apparent in UEs
Chorea
Movement disorder with features of both chorea and athetosis
Choreoathetosis
Sustained involuntary contractions of agonist and antagonist muscles
Dystonia (dystonic movements)
Large-amplitude sudden, violent, flailing motions of the arm and leg of one side of the body
Hemiballismus
Abnormally increased muscle activity or movement
Hyperkinesis
Decreased motor response especially to a specific stimulus
Hypokinesis
Increase in muscle tone causing greater resistance to passive movement; greater in flexor muscles
Rigidity
Lead-pipe (type of rigidity)
Uniform, constant resistance as limb is moved
Cogwheel (type of rigidity)
Series of brief relaxations or “catches” as limb is passively moved
Involuntary, rhythmic, oscillatory movement observed at rest
