In treating sports injuries, one of the major distinctions to general TCM (Traditional Chinese Medicine) diagnosis, theory & treatment is the addition of using motor points. According to Matt Callison, L.Ac. from the Motor Point Index (MPI), a motor point is a small dime-sized area in every muscle where the nerve enters the muscle belly. Acute trauma, repetitive stress, and overuse can cause muscle dysfunction, damage to soft and connective tissue, and muscle imbalance. When the body is not working in balance, the body becomes more vulnerable to re-injury and chronic pain. By stimulating the motor points, a signal is sent to the brain to either strengthen a weak muscle or relax a contracted one. Using motor points for orthopedic disorders can increase strength, flexibility, and range of motion.
