The tibial nerve lies directly posterior to the artery. It divides into two branches after exiting the tarsal tunnel, forming the plantar nerves. The therapist attempts to identify the nerve by hooking around it (like with a guitar string). by using a pointed palpation technique perpendicular to the structure. The nerve rolls away underneath the palpating finger when it has been exactly located. It is not possible to precisely identify the vein using palpation.
