evaluation of motor control dysfunction Flashcards
(19 cards)
modified ashworth scale (MAS)
tests for spasticity
MAS 0
no increase in muscle tone
MAS 1
slight increase in muscle tone with catch and release or minimal resistance at the end of the ROM in flexion or extension
MAS 1+
slight increase in muscle tone with a catch followed by minimal resistance through the remainder (less than half) of the ROM
MAS 2
marked increase in muscle tone through most of the ROM, but affected parts are easily moved
MAS 3
considerable increase in tone, passive movement is difficult
MAS 4
affected part is rigid in flexion or extension
dysmetria
undershooting (hypometria) or overshooting (hypermetria) of a target
dyssynergia
breakdown in movement resulting in joints being moved separately to reach a desired target as opposed to moving in a smooth trajectory; decomposition of movement
dysdiadochokinesia
impaired ability to perform rapidly alternating movements
ataxia
loss of motor control including tremors, dysdiadochokinesia, dyssynergia, and visual nystagmus
resting tremore
involuntary tremor noted at rest
rigidity
increased resistance to passive movement throughout the range (cogwheel or lead pipe)
bradykinesia
overall slowing of movement
akinesia
ability to initiate movements
athetosis
dyskinetic condition that includes inadequate timing, force, and accuracy of movements in the trunk/limbs; movements are writhing and worm like
dystonia
involuntary sustained distorted movement or posture involving contraction of groups of muscles
chorea
involuntary movements of the face and extremities which are spasmodic and of short duration
hemiballismus
unilateral chorea characterized by violent, forceful movements of the proximal muscles
