Thoracic Outlet Syndrome (TOS)

Thoracic outlet syndrome is a disruption of the normal function of the nerves leaving the cervical spine and innervating the upper extremities.  This is most often caused from an impingement of either the nerve itself, or its blood supply.  Often, the impingement site is located where the nerves pass through tight muscle groups (particularly the pectoralis minor and scalene muscles).  Active Release and adjusting the cervical spine can normalize muscle tension and relieve the impingement site.  A postural analysis and rehabilitation are needed to avoid reoccurrence.
