I have a tetraplegic client who, not only has no use of limbs, but also requires a tracheostomy ventilator system. He has full facial control, speech, and a reasonable degree of head control.
My client drives his powered recreational chair (a Boma 7) by using his chin to operate a joystick mounted on a stalk fixed to the chair frame. The main problems with this arrangement are : as he traverses rough ground his head rocks out of phase with chair movement so producing undesirable drive commands, he occasionally gets his chin into a position where he cannot correctly control the joystick and the effort required to perform chin movements is quite tiring over time.
I have suggested a magnetic tongue stud working in conjunction with a series of mouth or head mounted magnetic sensors but my client is not in favour with this option.
I would appreciate experiences or variety of ideas from panels with respect to using alternative control systems.
