Mechanical Outcomes of a Rolling-Joint Prosthetic Foot and Its Performance in the Dorsiflexion Phase of transtibial Amputee Gait
Mark R. Pitkin, PHD
The author describes a pilot biomechanical study designed to evaluate a new rolling-joint prosthetic foot (RJF). The preliminary study indicates use of the RJF results in simulation of a more natural moment of resistance in the dorsiflexion phase of ...

Voluntary-Opening Prehensors with Adjustable Grip force
Daniel D. Frey, MS
Lawrence E. Carlson, DENG
Vidya Ramaswamy, MS
The authors suggest the low percentage of upper-limb amputees who use prostheses may result from the limited function and flexibility of the devices currently available. In response, two prototype vector prehensors that allow grip force to be adjuste...
