Relevance – Most persons with upper-limb amputation use body- powered prostheses but must choose between voluntary opening and voluntary closing devices.

Measures – Southampton Hand Assessment Procedure to examine functional difference between opening and closing prehensors. – Survey to determine prehensor preference for specific tasks and assess possible advantage of prehensor that switches between modes.

Subjects agreed on which types of tasks they preferred to do with each prehensor.
