Dear all,
I am working with a person who has facial expression only. Uses a
ventillator on a trachy. No head movement.
The person can frown, raise eye-brows and grin.
I have tried EMG ( doesn't like pads on skin ), Liberator P-switch ( doesn't
like head band ) to pick up on frown.
Also tried eye-blink. Doesn't like idea of spectacle frame.
I have experimented with roller microswitch again on headband to pick up on
frown without success.
I would be very greateful for any advice anyone can offer.
thanks
