Upper extremity osteopathy

The flexibility of the upper extremity results in a wide range of movements across the shoulder, elbow, and wrist joints, which often leads to excessive and directionally awkward stress. The upper extremity is attached to the torso through multiple muscular attachments and one bony attachment (the sternoclavicular joint). Therefore, osteopathic examination and treatment are often first directed at the cervical and thoracic spine. Dysfunction can be present in any of the cardinal directions of each joint, as well as the radial head of the humerus. Osteopathic treatment in this region mostly consists of articulatory techniques, muscle energy, and high-velocity low-amplitude.
