A regular stretching regime to keep muscles and tendons supple should be part of a young man's daily routine in order to help prevent the development of contractures. Contractures are a tightening of the muscle and tendons, which limit the full range of movement in a joint. They are inevitable if a regular stretching program is not part of a boy's daily regime. This tightness occurs because not all muscles lose strength at the same time or pace, and boys with DMD develop irregular postures to compensate for this uneven weakness. This CD walks you through different types of stretches for DMD.
