Home health physical therapy can treat a wide range of conditions and injuries. After an injury or surgery procedure, it's common that the affected body part is immobile for a long period of time during the healing process. A key part of physical therapy is ensuring that we safely begin using the injured areas of the body so that we can regain full range of motion. As time passes and without professional help from a physical therapist, there's potential to never regain full range of motion in affected limbs and body parts.
