THE PROBLEM: The subject wanted to be able to play the trumpet. Unfortunately he was born with a degenerative muscle condition preventing him from holding and operating the trumpet and confining him to a wheelchair.
THE SOLUTION: The idea was to modify the trumpet so that the valves could be triggered electrically, through use of solenoids attached to the trumpet valves. A frame was built to mount the trumpet, switches and necessary control circuity to the subject's wheelchair. The switches were positioned on the frame to permit their operation with wrist, knee and foot. The frame was made to be completely adjustable to handle growth of the subject, provide a comfortable range of application and to allow use by different body types.
