Comparison of body-powered voluntary opening and voluntary closing prehensor for activities of daily life. J Rehabil Res Dev. 2014;51(3):253–62. Slideshow Project DOI: /JRRD JSP Aim – Determine whether using voluntary opening or voluntary closing device makes functional difference in activities of daily living. – Assess possibility of providing both functions in one device. Relevance – Most persons with upper-limb amputation use body- powered prostheses but must choose between voluntary opening and voluntary closing devices.

Slideshow Project DOI: /JRRD JSP Method Subjects – 29 nondisabled (used body-powered bypass prosthesis). – 2 with unilateral transradial amputation (used conventional body-powered device). 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.

Comparison of body-powered voluntary opening and voluntary closing prehensor for activities of daily life. J Rehabil Res Dev. 2014;51(3):253–62. Slideshow Project DOI: /JRRD JSP Results Voluntary closing prehensor was 1.3 s faster than voluntary opening prehensor across tasks. Subjects agreed on which types of tasks they preferred to do with each prehensor.
