To date, no studies have been done to look at the effect of pre-operative conditioning on sensory reinnervation of human peripheral nerves with ES. Given the promising nature of the animal data from Senger et al, and the well documented effectiveness of post-operative electrical stimulation of surgically repaired peripheral nerves, we designed this study to evaluate the effects of pre-operative conditioning with ES, as well as pre-operative and post-operative ES on digital nerve sensory recovery post transection and repair.
