The purpose

The purpose of this study is to optimize the Defense Advanced Research Projects Agency's (DARPA) advanced upper limb prosthesis, the Modular Prosthetic Limb (MPL), by evaluating the performance, usability, and patient acceptance of the MPL in a clinical setting. This study will be a non-randomized limited clinical optimization study. The study will consist of two phases. Up to twenty-four upper extremity amputees will be recruited in order to ensure twelve subjects for participation in the study: 6 trans-humeral amputees and 6 trans-radial amputees. During Phase 1, subjects will be evaluated for their potential to operate the MPL using a virtual limb controlled by signals from surface electromyograms (sEMG). The first six trans-humeral amputee subjects and the first six trans-radial amputee subjects with a demonstrated proficiency controlling the MPL based on analytical performance metrics will enter Phase 2. During Phase 2, each subject will be fitted for the prosthesis with a custom socket. The user will then evaluate the prosthesis during twelve 1- hour or 1 and one half-hour sessions, working with an occupational therapist and research associates and completing both quantitative and qualitative assessments.
