Thoracic Outlet Syndrome

​TOS or thoracic outlet syndrome typically presents with diffuse arm numbness and tingling often following a path down the inside or medial aspect of the arm.  This will often extend into the 3rd and 4th digits of the hand and is often aggravated by activities involving overhead movements.  TOS is most commonly due to compression of the brachial plexus and/or axillary and subclavian arteries at different locations of the shoulder and/or arm.  These compressions may be caused by overuse of the shoulder and arm, presence of a cervical rib that is determined by x-ray visualization, traumatic injury, muscular inflammation and incorrect posture. 

​Common muscle groups involved in thoracic outlet cases include the scalenes, pectorals, and muscles within the costoclavicular and subcoracoid areas.  Chiropractic care can approach TOS focusing on postural and movement pattern training, muscular rehabilitation that focuses on strengthening weakened or inhibited muscles, stretching of tight and over-worked muscles, adjusting regions of the cervical and thoracic spine, and trigger point therapy.
