An OT is working with a client experiencing upper extremity weakness from a spinal cord injury
The client wants to be able to use her arm to drive a power wheelchair. The therapist has set up a MAS, but the client is having difficulty horizontally abducting her shoulder enough to reach the joystick control. Which adjustment can the therapist make to facilitate this motion?
A. Roll the semireclining mount outwardly.
B. Pitch the semireclining mount toward the rear of the wheelchair.
C. Lower the semireclining mount on the wheelchair upright.
D. Move the rocker arm more proximally on the forearm support.
ANS: A
Adjusting for horizontal motion such as horizontal abduction and adduction is done by rolling the semireclining mount. Rolling it outwardly will facilitate horizontal abduction. Pitching or lowering the semireclining mount or moving the rocker arm would not solve the problem.
