Yes, this is one of the risks I need to consider, the joystick itself
weighs approx 300g, the mounting would be mocked up at first with broad
padded shoulder straps, I had envisaged the final product having padded
neoprene (no seams in contact with the user) straps for comfort.
The other risk I need to consider is the inadvertent operation of the
joystick during spasms. The small control unit with the joystick also
needs careful placement to prevent water ingress.
I may notice more risks during trials, have I missed anything? Comments
welcome.

Hi Garry
Would the risk of developing pressure sores be a factor in this case?
Regards,

Thanks for all the replies, according to the website therafin do not
have a UK distributor. We use an orthotic company to make supportive
wheelchair seating, they have agreed to make a breastplate for me to
trial.

harmonica holder. I haven't seen it and haven't managed to buy a
harmonica holder yet!

Hi Garry
I don't know of a suitable shoulder harness on the market.
We did have a trial fitting of a larger remote joystick fitted to a
small chest plate. The chest plate had webing straps that crossed
over
the patient's back. We included some up/down and forward/back
adjustment. This mounting method was an adaptation of a mounting
method
that we have used much more successfully for switches. The main
difficulty was the weight of the joystick as this caused the plate to
tilt forward.
We tried this method because the problem was similar to the one you
describe, the patient had difficulty maintaining his position in his
powered wheelchair and frequently got into positions where he could no
longer reach the standard chin joystick fixed to the chair.
So I agree the idea is worth trying and you should have a much better
chance of success with the Dynamic mini joystick.

I am looking for a way of mounting the new Dynamic mini joystick on a
suitable shoulder harness?
The user is frequently home alone and also suffers from occasional
spasms, he is high level tetraplegic and the spasms could leave him
unable to reach the joystick if it were mounted to the powerchair. I
would of course be completing a risk assessment for the method of
mounting.
Has anyone had any experience? Where can I purchase a shoulder harness
suitable for adaption?
