It belongs to the superficial flexors of the forearm, together with pronator teres, flexor carpi radialis, flexor carpi ulnaris and palmaris longus. The healing stages of tendons include three phases[15][16]: Therapists need to have knowledge about the anatomy, the pulleys, tendon injury zones and the tendon healing stages as this will inform the treatment approach. Come back to the start position by doing all of the above backwards. At the bottom, repeat the sequence again Stretching: Programs that are too long, need extra equipment or various weights, offer a potential roadblock to compliance. Early pioneers broke down the EMG activity of each muscle during each pitching phase, which led to the development of the original gold standard of arm care programs: the Throwers Ten. Rarely, carpal tunnel syndrome can be caused by an aberrant muscle belly arising from the tendon of flexor digitorum superficialis that compresses the median nerve. Although not all arm care programs have gone through the rigors of studying their effectiveness in the field, these studies by Sakata et al.8,9 highlight the potential impact of using arm care interventions. This anatomical variation in the muscle insertion can complicate diagnoses of injury to the smallest digit.
