About

To compare the use of the semi-autonomous control algorithm (condition 1) with the standard of care myoelectric system used with the TASKA prosthetic hand (condition 2). Able bodied subjects will enroll in a laboratory based experimental session at the University of Colorado at Boulder. Subjects will be fitted with a by-pass prosthesis which enables the able-bodied subject to control the prosthetic hand using the myoelectric signals on their able limb. A TASKA prosthetic hand will be sensorized using the Point Touch technology. In a randomized order, the subjects will perform functional tasks evaluating dexterity and assistance with prolonged gross motor movement using each experimental condition. Then, a direct comparison can be made across subjects for the semi-autonomous control algorithm and the standard of care myoelectric system used in the TASKA prosthetic hand.
