Electrical stimulation of the distal sciatic nerve can help people who have lost control over their legs to stand or walk. We need to better understand the nerve anatomy to design better nerve electrodes. Nerve fascicles from branches of human sciatic nerves were traced to create fascicle maps. Sciatic nerve branches were consistently represented as individual fascicles or distinct groups of fascicles in the sciatic nerve. Sciatic nerves were relatively elliptical. Selective stimulation of functional muscle groups is therefore possible with a single nerve cuff electrode and may improve ankle control for standing and walking functions.
