Healing occurs in an orderly fashion. Each stage of healing needs to be treated differently in order to increase the strength of the muscle. Physical therapists can help guide through these stages, help healing to occur correctly, and decrease the chance of other injuries occurring while the muscle is weak and vulnerable. When the muscle heals, it has to scar over just like a cut on your skin. If this scar tissue does not lie down properly, it can change the way that muscle works forever. A physical therapist can help to decrease this scar tissue and make sure it does not damage your movements.
