Electrodes are applied near to the ankle where the tibial/sural nerve is located. Pangi valley is divided into the Saichu, Hudan Bhatori and Sural Bhatori valleys. This usually is the great auricular nerve or sural nerve. However, conduction velocity of the Sural nerve is not associated with age. Nerve conduction studies can be used to delineate sural nerve lesions. It gives the aural communicating nerve which joins the sural nerve in the midcalf. Sometimes inflammatory or vasculitic diseases will selectively involve the sural nerve. "Sural" means related to the calf. Sural nerve damage is usually part of a more generalised peripheral neuropathy. The sural nerve is rather superficial, which makes it more accessible to surgeons. A commonly used nerve for autotransplantation is the sural nerve in the upper leg. Sural nerve (innervating the lateral portion of the foot)4. The sural nerve is a sensory nerve in the calf region (sura) of the leg. Sural nerve (SN) stimulation results in a reflex that is both phase and intensity dependent. The lateral sural cutaneous nerve originates from the common peroneal nerve.
