UE function Flashcards
three aspects of grasp
postural control
transport (reach)
manipulation(grasp)
manipulation and grasp requires
visual feedback
sensation
tactile input
grasp aperture
is feedforward at start of end of reach
start
prerequisite for hand use
reach
looking
postural adjustment
somatosensory information (grasp)
vision needed for UE function
feedforward and feedback
visual info (eye head trunk movement)
move head ind of trunk
stabilized gaze
parts of reaching
pre shaping hand
parts of transport
elbow flexion, ext
shoulder flex, ER
U/R deviation
supination
parts of grasping
MCP/IP flexion
radial deviation
w ext
factors that may influence reach and grasp
altered cognition / sensation pain weakness mm imbalnce disturbed motor unit activation altered postural control
reaching impairments after stroke
mm weakness variability in perfomrance decrease accuracy / smoothness delated reaction sensory loss
grasping after stroke impairments
can’t sustain grasp
difficulty pre shaping
difficulty lifting
is grasping or releasing harder for stroke
releasing
manipulation after stroke
can flex can’t extend, hard to release
clumsy
lack cooperation of mm
recovery
for ppl showing motor recovery signs
compensatory
for ppl expecting outcome of poor motor recovery
