Clinical notes

Xiāoliào is a significant local point for treating pain and stiffness in the shoulder, scapula, and neck region. Its location in the supraspinous fossa makes it effective for conditions involving the supraspinatus muscle, such as rotator cuff impingement or strain. Although the classical texts provided focus on the term 'xiāoshuò' as a pathological process of heat consuming the body, the point itself is primarily used in modern practice for musculoskeletal issues of the upper back and shoulder.
