Study Summary
The investigators will investigate the device feasibility of human peripheral nerves and muscles recording and stimulation using percutaneous Utah Slanted Electrode Arrays (pUSEAs) implanted into residual peripheral arm nerves and EMG electrodes implanted in the residual muscles of patients with limb amputations in order to determine the ability of the HAPTIX (Hand Proprioception and Touch Interfaces) System to control an upper-extremity prosthesis, and to provide a sense of cutaneous touch and muscle proprioceptive feedback to the amputee.
Primary Outcome
Three participants after receiving a stimuli will have action potentials (millivolts, mV) arising from the axons surrounding the tip of each electrode recorded in time. The moving action potentials (mV) measure five phases: resting potential, depolarization, peak, repolarization, and hyperpolarization.
