Design and evaluation of two different finger concepts for body-powered prosthetic hand. J Rehabil Res Dev. 2013;50(9):XX–XX. http://dx.doi.org/10.1682/JRRD.2012.12.0223 Slideshow Project DOI:10.1682/JRRD.2012.12.0223JSP Aim – Find efficient energy transmission method for body-powered prosthetic hand. Relevance – Mechanisms in prosthetic hands should have low mass and be able to deliver pinch force with only small amount of input energy.

Design and evaluation of two different finger concepts for body-powered prosthetic hand. J Rehabil Res Dev. 2013;50(9):XX–XX. http://dx.doi.org/10.1682/JRRD.2012.12.0223 Slideshow Project DOI:10.1682/JRRD.2012.12.0223JSP Method Designed and tested pulley-cable finger and hydraulic cylinder finger. – Compared pulley-cable transmission principle with hydraulic cylinder transmission principle. Both fingers had identical dimensions and low mass. – Measured input energy for several tasks. (a) (b) Figure. (a) Pulley-cable finger. (b) Hydraulic cylinder finger.
