Motor Impairments: Basal Ganglia Pathology Flashcards
AKINESIA
Inability to initiate movement: associated with fixed postures
ATHETOSIS
slow, involuntary, rithering, twisting, “worm-like” movements; frequently greater involvement in distal upper extremities
- NECK, FACE, TONGUE, AND TRUNK
BRADYKINESIA
Decrease amplitude in velocity of voluntary movement
CHOREA
Involuntary, rapid, irregular, jerky movements involving multiple joints: most apparent in Upper Extremities
CHOREOATHETOSIS
Movement disorder with features of both chorea and AtHetosis
DYSTONIA
Sustained involuntary contractions of agonist and antagonist muscles
HEMIBALLISMUS
Large amplitude sudden, violent, flailing motion of arm and leg of one side of the body
HYPERKINESIS
Abnormally increased muscle activity or movement
HYPOKINESIS
Decreased motor response, especially to a specific stimulus
LEAD-PIPE RIGIDITY
Uniform constant resistance as limb is moved through ROM
- CONSTANT STIFFNESS
COGWHEEL RIGIDITY
Series of brief relaxations or “catches” as limb is passively removed
- TIGHT, RELAXED, TIGHT, RELAXED
TREMOR (RESTING)
Involuntary, rhythmic, auscultary movements observed at rest
- PRONATION AND SUPINATION MOVEMENTS
- APPEARS @ JAW TOO
