Physical Therapy in Lowell for Shoulder
Welcome to TheraFit Physical Therapy's patient resource about quadrilateral space syndrome.
Quadrilateral space syndrome (QSS) happens when the axillary nerve is compressed, or injured in the back of the shoulder. Sometimes the symptoms are caused by the compression of an artery in the same area.
Quadrilateral space syndrome usually happens from overuse, especially with overhead sports like throwing and swimming. The syndrome can also be caused by an injury, like a shoulder dislocation.
