Colleagues,
Here is the answer to my previous post: I am looking for a component which I
have seen before but cannot remember where. It is a powered cable puller
which can be installed in the forearm of a TH prosthesis. I am fitting an 84
yr. old. female TH patient who is getting tired of the body powered system
and is limited by RA pain. We are considering a proportional linear
potentiometer built into the harness coupled to a powered split hook
termial. However, the elusive device I mentioned above would allow her to
keep the low bulk, familiar shape and lighter weight of her Hosmer 7XA hook

HOSMER MAKES A N.Y. PREHENSION ACTUATOR WHICH IS AN EXTERNALLY POWERED
DEVICE BUILT IN TO THE FOREARM OF A TH PROSTHESIS. IT RECEIVES AN ELECTRONIC
SIGNAL FROM ELECTRODES OR SWITCH, UPON WHICH IT PULLS ON THE CABLE CONNECTED
TO THE TERMINAL. IT THEREBY CIRCUMVENTS THE NEED FOR A HEAVY, BULKY AND AND
LESS RUGGED ELECTRIC TERMINAL. IT CAN BEEN SEEN AT WWW.HOSMER.COM , BOOK 3
HOSMER DORRANCE EXTERNALLY POWERED DEVICES.
THANK YOU FOR YOUR RESPONSES.
