Pre-clinical assessment of an intuitive prosthetic elbow control strategy using residual limb motion with osseo-integrated patients

By Kirstin Ahmed

In this assessment, a model for shoulder/elbow coordination guides a motorized elbow using movement in the residual limb. This control strategy was enabled by attaching the prosthetic limb to an abutment anchored to the skeleton (osseo-integration), allowing the residual limb to move more freely. Combined with a myoelectrical controlled hand, an improvement was seen in the form of less compensatory movements when using automatic shoulder/elbow coordination.
