Electrical stimulation of the femoral nerve can help people who have lost control over their legs to stand or walk. We must better understand the nerve anatomy to design better nerve cuff electrodes. We traced nerve fascicles from branches of human femoral nerves to create fascicle maps. Femoral nerve branches were consistently represented as individual fascicles or distinct groups of fascicles in the femoral nerve. Femoral nerves were relatively flat. Intraoperative measurements in six subjects were consistent with cadaver results. Selective stimulation of individual muscles is therefore possible with a single nerve cuff electrode and may improve standing function.
