Feasibility of Implantable Myoelectric Sensors to Control Upper Limb Prostheses — IMES  

Amputation, Traumatic Clinical Trial

Official title: A Feasibility Study to Assess Safety and Functionality of Implantable Myoelectric Sensors for Upper Extremity Prosthetic Control in Transradial Amputees

Status Completed

Clinical Trial Summary

This study will evaluate the feasibility of using implanted myoelectric sensors (IMES) to control an electromechanical prosthetic wrist and hand.

Clinical Trial Description

The study assesses the feasibility of an advanced prosthesis control system aimed at development of a more intuitive and functional prosthetic device. Tiny (2.5 mm by 16 mm) Implantable Myoelectric Sensors (IMES) will be implanted into the residual forearm muscles of three transradial amputee subjects. These devices wirelessly transmit electrical muscle signals to an electromechanical prosthetic wrist and hand.

Following a two-week recovery from implantation of six to eight IMES into residual forearm muscles, subjects will initiate seven months of training. Subjects first train for approximately a month using a bench-top IMES system. When they receive their custom-fit IMES Prosthesis (including electromechanical wrist and hand) subjects initiate six months of additional training. Subjects will then be given the option to use the IMES Prosthesis for another sixteen months. The usability and functionality of the prosthetic system will be evaluated throughout the study. ;
