Motor control and learning with lower-limb myoelectric control in amputees

Ramses E. Alcaide-Aguirre, BS, et al.

We studied subjects with lower-limb amputation and nondisabled subjects while they used their muscle electrical activity to control a virtual object on a computer screen. The subjects changed the acceleration of the virtual object based on the relative amplitude of their muscle activity. We wanted to know whether the subjects with amputation could learn to change the activity level of their residual-limb muscles. We found that the subjects with amputation only needed a very short amount of practice to quickly improve their residual-limb muscle control and even match the level of the nondisabled subjects. These results suggest that a similar control strategy could be used for robotic lower-limb ankle prostheses.
