Rose, a TENS unit isn't designed to stimulate motor fibers, although it sometimes will a little bit if turned up high and placed just right. There are other units designed to stimulate motor nerves to get muscles going. Since you are getting a return of nerve function, I think a physical therapist could help you if you have insurance coverage for this. A therapist could evaluate you and set you up with an FES unit (Functional Electrical Stimulation) -- those are designed to stimulate motor function.
