For active comparator intervention 1 (myoelectric direct control prosthesis): Naïve to use of myoelectric prosthesis (i.e., uses body-powered prosthesis or has not used a myoelectric prosthesis for at least 3 years)
For active comparator intervention 2 (myoelectric pattern recognition control prosthesis): Currently uses a commercially-available pattern recognition system (IBT Sense) with a terminal device having at least two degrees of freedom

Exclusion

Significant cognitive deficits as determined upon clinical evaluation

What this trial measures

  • Fitt's Law Throughputat one week

    The investigators will use throughput as the primary outcome measure for the Fitt's Law task. Throughput is defined as the ratio of index of difficulty to the movement time required for successful completion.

  • Southampton Hand Assessment Procedure (SHAP)at two weeks

    The Southampton Hand Assessment Procedure (SHAP) will be the primary clinical outcome measure. The SHAP is a time-based test of a standardized protocol of 26 timed activities of daily living (ADL) tasks. The SHAP has a set of common objects representative of everyday items for the user to pick up. The results of the SHAP is a score which directly compares the abilities of the subject with those of intact able-bodied individuals as well as more refined scores for six prehensile patterns. A SHAP score of 100 is what an intact person is expected to achieve. Lower scores indicate worse function. This test has been validated for normative data.
