Assessment of an Automatic Prosthetic Elbow Control Strategy Using Residual Limb Motion for Transhumeral Amputated Individuals With Socket or Osseointegrated Prostheses

Prostheses are conventionally controlled via signals acquired from muscles. An amputation above the elbow leaves patient with a limited number of muscles and thus with few signal sources for controlling a prosthesis. Here we investigated an automatic elbow controller, leaving the muscle generated signals to open and close the hand. The automatic elbow controller reduced compensatory movements and was perceived as intuitive by the patients.
