Grab two heavy dumbbells (remember, heavy is relative) that you can hold for around 30 seconds (it may take trial and error to find your ideal weight). Active flexion can start from day one post-surgery. Hip shoulder separation is related to trunk velocity and ultimately pitch velocity.27 Therefore, training interventions to improve pelvic-trunk axial dissociation may increase maximal trunk rotation velocity.27. Surface electromygraphic analysis of the lower trapezius muscle during exercises performed below ninety degrees of shoulder elevation in healthy subjects. During the pitching motion the infraspinatus reaches its peak MVC during late cocking (74%).2 This exercise increased EMG activity over 21% MVC between 60-90 of shoulder flexion, allowing for a safe option for infraspinatus strengthening without placing the shoulder in an impingement position.24. The posterior deltoid reaches levels of 93% MVC during this exercise.5, This exercise was chosen to address both lower trapezius and posterior deltoid strengthening.

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.
