Since these studies showed that as little as one hour of electrical stimulation was effective in accelerating nerve regeneration, it opens the possibility of applying this to humans. The intervention is safe and of minimal discomfort. Furthermore, the use of electrical stimulation as a clinical treatment modality is already well accepted. In a recent study, the investigators applied this to patients with severe median nerve compressive injury in the carpal tunnel following surgery. The procedure was well tolerated with no adverse event observed in any of the 21 subjects after 1 year of follow up. In fact, compared to the control subjects who received surgery alone, those in the treatment groups showed quicker resolution of their symptoms and more vigorous motor nerve regeneration.
