Abstract

A bottleneck in upper limb prosthetic design is the myoelectric control algorithm. Here we studied the clinical readiness of the myoelectric postural control algorithm in a laboratory setting with two trans-radial amputees using a commercially available prosthetic limb system. The postural control algorithm was integrated into prosthetic limb systems using standard of care components. A comparison between a commercial state of the art system (the i-Limb Revolution state-based myoelectric controller) and the postural controller was performed using the Southampton Hand Assessment Procedure using a self-contained prosthesis system. The SHAP scores indicate that the postural controller provided an average of 66% of hand function compared to an intact limb. The myoelectric postural control algorithm is shown to be a clinical ready system for users of multi-functional prosthetic hands.
