A muscle that is very tight remains in a contracted position, even when at rest. Circulation to the muscle is then reduced, and as a result, the muscle loses elasticity. Gradually, the muscle becomes fixed in a shortened position. Full range of motion will no longer be possible. Reversal of this condition is highly unlikely unless the muscle fibers are released by an experienced practitioner. Rest will not change the pain and restriction of severely contracted muscles. Skilled hands can relieve the discomfort and dysfunction of constricted muscle fibers. The body worker is a detective, putting together pieces of a puzzle to rebuild proper posture , movement, and alignment.
