We will investigate basic physiology of human peripheral nerves and muscle leads using high-count microelectrode arrays implanted into peripheral nerves and muscle of patients with limb amputations or peripheral nerve injury.
We will also concurrently investigate the use of intramuscular leads into residual forearm muscle to control external device. This will give us a direct comparison between two proposed methods of motor control: 1: Intraneural electrodes which is the new technique and 2: EMG which is currently used in a cruder transcutaneous method with this version allowing more specific inputs relating directly to hand function and placed intramuscularly.
