Intraoperative Peripheral Nerve Stimulation

The purpose of this research study is to find out if using direct electrical stimulation during surgery is safe and helpful for people with nerve problems caused by compressed nerves.

Inclusion Criteria: * Nerve root stimulation arm: Clinical and radiographic findings of compressive neuropathy at the level of the nerve root, including myelopathy and/ or radiculopathy, who are planning for minimally invasive or open spine surgery to decompress the nerve. * Peripheral nerve stimulation arm: Compressive peripheral neuropathy, including cubital tunnel, carpal tunnel and peroneal nerve compression who are planning to undergo surgical decompression in the affected upper extremity. Exclusion Criteria: * Patients that had previous nerve transfers for cervical spinal cord injury or tendon transfers, as they would not benefit from this procedure. * Any implanted electronic devices, including pacemakers * Pregnant or nursing
