A system for restoring muscle function to the lumbar spine to treat low back pain is provided. The system may include one or more electrode leads coupled to an implantable pulse generator (IPG) and a tunneler system for subcutaneously implanting a proximal portion of the lead(s). The system may also include a handheld activator configured to transfer a stimulation command to the IPG, and an external programmer configured to transfer programming data to the IPG. The stimulation command directs the programmable controller to stimulate the tissue in accordance with the programming data. The system may include a software-based programming system run on a computer such that the treating physician may program and adjust stimulation parameters.
