Muscle surgery has many purposes.  Muscles are rich in blood vessels and so muscles are sometimes moved by surgeons to damaged areas to bring in blood supply.

All too often we hear about things being too strong or too weak. Yet, the walking and function of very strong people and frankly weak people differs very little. Most normal function does not call upon great reserves of strength. Muscle power can be missing by 2/3 ^rds and not show up as a disability depending on what that person requires occupationally.

Therefore, most muscle surgery is about balance and control. In disorders of the nervous system, the reflexes that muscles elicit when tugged on or signaled to act determine many of the features of the disability. Work-arounds to limit those reactions are many.
