Hi, I've used these a few times successfully and specifically for guys with DMD. The one that's working best at the moment is very thin and has a Spectra Riser. The only simple way to provide paediatric pelvic positioning is to use large in fill pads. He has the mini joystick strapped to the front of the in fill block with a simple strap of Velcro. This holds it securely and can readily be adjusted to suit on a daily basis. Trays aren't always necessary nor liked and I'm sure you'll check whether trunk control is OK without the tray. I agree that trays aesthetically aren't great especially for teenagers. The finger in hole is not water proof either. Good luck.

Good lateral thinking to turn the joystick through 90degrees! That's quite a possibility.

[mailto:[log in to unmask]] On Behalf Of Matthew Pepper Sent: 17 August 2010 11:01 To: [log in to unmask] Subject: Re: small joysticks for MD lads Barry, We have mounted mini-joystick on the tray - using an ABS former and velcro. For one client the joystick was mounted in the conventional upright position. For the other on its side and activated via the patients index finger knuckle. In both cases we also manufactured arm supports/troughs to velcro onto the tray so that the arm/hand was at the correct height and in the correct position. We found that with both patients the 10gm activation force was ideal and they managed proportional control. The challenge was to provide reliable and repeatable positioning for access.

Technically they work fine, but my client doesn't have enough movement for them. What are people using? He hasn't tried the DX mini, because so far, he won't accept mounting it in a hole in the wheelchair tray. Does the 10g deflection give us a better chance than the 50g of the Wii? I don't think he's tried the DX "finger in the hole" joystick. Have people had success with this in Muscular Dystrophy?
