The effect of brief conditioning electrical stimulation on nerve regeneration has been showed to be efficacy in animal studies. In this double-blind, randomized, controlled study, the investigators will compare the physiological and functional improvements post surgery compared with the controls who received surgery alone. Because electrical stimulation is reasonably well-tolerated and the treatment only takes an hour, it is a potentially feasible clinical tool for patients with severe nerve injury.
Cubital tunnel syndrome is the second most common compression neuropathy. In severe cases, functional recovery, even with surgery, is often poor. Therefore, alternative adjunct treatments capable of increasing the speed of nerve regeneration are much needed.
