The different approaches for electric stimulation in peripheral nerve damage. (A) Implantation of electrodes over the severed end of the axons. (B) Implantation of an electrically conductive nerve conduit over the nerve stumps. (C) Noninvasive stimulation by skin patch electrodes over the target muscle and the proximal end of the damage nerve. (D) Needle electrodes on target muscle and proximal end of the damaged nerve.
