FES and Biofeedback Flashcards
what is the point of E-stim
generate a motor contraction
what is the wave form of E-stim
usually square, can be a sine wave
duration?
how much current ur delivering
frequency
pulse per second or Hz, how fast it comes in
duty cycle
on/off time
how do motor neurons recruit fibers
type 1 first, then type IIa then type IIb
what happens in NMES motor neuron recruitment
everytype of fiber recruited at the same time, but larger fibers are recruited first (type II, the type 1) - this is not reproducing the natural way u generate force, also ppl fatigue sooner than they would normally
u take NMES and put it in combo with a functional activity (walking, reaching, closing hand,etc.), what does it become?
functional electrical stimulation (FES), ex, DF during gait
does FES to the supraspinatus and posterior delt in addition to convential treatment work better than conventional tx alone when treating shoulder subluxation in hemiplegic patients?
yes
are there lasting effects of FES?
no, when u take it away, benefits are gone
when can u perform FES post stroke?
at any time, its a low risk intervention
how do u increase the amount of biofeedback a person is getting from EMG?
put the electrodes further apart
whats the point of EMG?
biofeedback, lets them know when they are doing something right.
what is household ambulation speed
<.4 m/sec
limited community ambulation speed?
.4-.8 m/sec
