Carpal Tunnel Syndrome


Carpal Tunnel Syndrome (CTS) results from impingement of the Median Nerve, which runs from the neck, down the arm, then through bones in the wrist (carpal tunnel), to supply the hand and thumb. Irritation to this nerve often results in numbness, tingling, and pain in the hand and thumb, loss of grip strength in the hand and thumb, and pain / numbness radiating from the neck and arm.

How Upper Cervical Care Relates to Carpal Tunnel Syndrome

In a review of medically confirmed carpal tunnel syndrome cases, it was discovered that the majority of patients examined also had concurrent problems with the cervical spine.1 Because nerve roots from the cervical spine form the median nerve in the arm, it has been suggested that cervical problems can contribute to the onset of CTS.2-18 Many of these patients do not respond to conservative and/or surgical treatment directed solely at the wrist. Because cervical nerve irritation and/or compression renders the lower nerves in the wrist more susceptible to injury, it is essential to properly correct the cervical problem first if the wrist condition is to fully resolve.

The purpose of upper cervical care is to correct cervical spine mechanics that are irritating spinal cord tracts and nerve roots that extend to the wrist. A similar phenomenon can occur with Thoracic Outlet Syndrome (TOS) and cervical radiculopathy (tingling, pain down the arms). While many carpal tunnel sufferers recall specific traumas such as head injuries, auto accidents or falls, which could have injured their cervical spines, some do not. An evaluation is necessary in each individual's case to assess whether an upper cervical injury is present and whether benefit from upper cervical care can be achieved.
