Virtual Training System for Mechanical Transhumeral Prostheses

Abstract

In Mexico, transhumeral amputation occurs due to traumatic etiology and represents 4% of all the amputations. These amputations occur during an active period of life, which limits work options and increase user demotivation. It is known that pre-prosthetic and post-prosthetic rehabilitation provides the necessary tools to improve range of motion, increase muscle strength and restore the sense of control to perform activities of daily living. For this reason, virtual therapy environments have been developed for myoelectric prostheses, leaving aside body-powered prostheses. This paper presents the design and development of virtual training system for body-powered transhumeral prostheses in pre-prosthetic therapy. The created device has allowed to efficiently simulate the control of the body-powered transhumeral prosthesis for the user and provides a tool with specific routines of occupational therapy to the therapist. Thus, this provide the opportunity to increase the acceptance of a prosthesis at a higher level.
