8. The Superficial Back Arm Line

     The Superficial Back Arm Line is the fascial connection from spine to fingers.  It controls arm movements behind our lateral midline (ex. A backhand tennis shot) but, for the most part, limits and contains the work of the Superficial FRONT Arm Line.  The SBAL also maintains control during abduction (lifting away from the body's midline) of the shoulder and arm; this can cause the line to get overworked when the rib cage or spine moves out of alignment with the shoulder girdle.
