Efficiency of Voluntary Opening Prosthetic Devices: Analysis of Required Work and Energy Dissipation

This study evaluates the required work to open devices by 50 mm and energy dissipated during one cycle of opening and closing by 50 mm on the Becker Imperial hand. The efficiency of voluntary opening prosthetic devices over 24 years of development is explored. SVO and VO were assessed without a cosmetic glove.
