Thoracic Outlet Syndrome

Quite a number of our patients that we see present with a numb and tingly feeling into their hand and fingers especially when typing, driving, or reaching overhead. Often times this can be caused by something called “Thoracic Outlet Syndrome” or “TOS” for short. TOS is characterized as neurovascular entrapment which means that there is compression occurring upon that neurovascular bundle which subsequently causes the numbness and tingling. There are a few primary places that TOS is caused. The compression can be caused by the scalenus anticus muscle or a cervical rib which is indicated by Adson orthopedic test. Another compression point is between the clavicle and 1st rib indicated by Eden orthopedic test and compression by the pectoralis minor or the coracoid process indicated by Wright test. Typically treatment for this syndrome includes a combination of adjustments to relief any interference to the involved areas, postural correction, trigger point therapy, and strengthening of the trapezius and rhomboid muscles (Differential Diagnosis for the Chiropractor-Souza). Often times, this syndrome is caused from poor neck posture that can be due to poor work environment or home environment ergonomics.
