Introduction
Skillful object manipulation in various activities of daily living requires accurate and economical modulation of grip force, yet experimental studies investigating grip force using a prosthesis are lacking. The purpose of this study was to compare grip force output between two types of upper-limb prosthetic prehensors. We hypothesized a relationship between grip force output and the muscular tension needed to control the prehensor.
Materials and Methods
Ten able-bodied participants attempted to produce a static target grip force using a voluntary opening and voluntary closing prosthetic simulator and their anatomical hand. The target forces were 0.49 N, 4 N, and …
