1. A method for implanting a device for restoring muscle function to a lumbar spine of a patient, the method comprising:
selecting a guide needle having a longitudinal axis and a distal tip;
selecting a lead having a distal region including one or more electrodes;
locating a first insertion site at a cranial edge of a transverse process of a target vertebrae of the lumbar spine;
inserting the distal tip of the guide needle percutaneously at the first insertion site;
locating a second insertion site along a midline of the target vertebrae; and
implanting the lead with a medial-to-lateral trajectory from the second insertion site toward the distal tip of guide needle such that the distal region is angled relative to the longitudinal axis of the guide needle and the one or more electrodes are disposed near or in contact with tissue associated with control of the lumbar spine,
wherein the medial-to-lateral trajectory traverses naturally occurring fascicle planes.
