Carpal Tunnel Syndrome

 Carpal Tunnel Syndrome

Carpal Tunnel Syndrome is the most commonly referenced Repetitive Motion Injury – a category of conditions that represent the fastest growing segment of injuries in American society today. Many factors have been blamed on this recent epidemic including increased computer usage, poor ergonomics, and improper medical treatment that is focused on masking symptoms rather than on prevention or correction.The term “carpal tunnel” refers to a tunnel formed by bones of the wrist through which nerves and tendons pass as they travel from the forearm to the hand. Although irritation of the nerves at the carpal tunnel is a common cause of this condition, there are usually other factors. “Trapped” nerves at the spine (usually the neck), pectoralis minor muscle of the chest, rotator cuff muscles of the shoulder and forearm muscles are commonly involved with this condition.

Repetitive “rubbing” of sensitive soft-tissues or chronic muscle tightness will initiate an injury cascade that will eventually lead to significant dysfunction and pain. Both of these situations deprive the soft-tissues of much needed oxygen due to a decrease in full muscle contraction and complete relaxation. This reduces the “pumping” action that normally occurs within healthy muscle tissue. A decrease in tissue oxygenation triggers fibroblastic activity – the primary mechanism involved in the formation of scar tissue. As the scar tissue builds, the tendons passing through the carpal tunnel thicken. This thickening decreases the amount of space available in the tunnel for the nerves. Eventually, the competition for space within the tunnel will lead to a compression of the nerves triggering the typical carpal tunnel symptoms. In other words, carpal tunnel syndrome can develop over months or years before the first symptom is ever experienced!

Treatment for Carpal Tunnel

A combined approach of corrective chiropractic adjustments and deep tissue muscle work is often the most effective approach.

Scar tissue adhesions located within and between soft-tissues are best removed using a muscle therapy. Deep tissue muscle treatments are an interactive process involving both doctor and patient.  Patients often notice improvement in their levels of pain, flexibility and strength within seconds following the treatment.

A chiropractor will begin by addressing the source of the problem. A chronic joint dysfunction of the neck, shoulder, elbow or wrist can force the muscles of the forearm to become “overworked”. This constant abuse can initiate the inflammatory cascade mentioned above that can eventually end with carpal tunnel syndrome. Chiropractic adjustments commonly correct these dysfunctions allowing the supporting musculature to return to a healthy, balanced state. Treatment of the muscle alone will likely provide only temporary benefit as the dysfunctional joint will merely cause the muscles to become unbalanced again over time. Likewise, ignoring the muscles and only treating the joints will often produce mediocre results as the muscles pull the joints back into dysfunction.

Is Surgery Effective at Treating Carpal Tunnel Syndrome?

Surgical procedures have been developed over the years to “release” the pressure on the nerves at the carpal tunnel by permanently severing the ligament that holds the tunnel together.

Unfortunately, these procedures are rarely successful over the long term and almost never address the cause of the nerve irritation. Common sense would tell us that it is unlikely that the carpal tunnel would simply “shrink” without warning. Therefore, increasing the size of the tunnel will only provide temporary benefit especially if the tendons within the tunnel continue to thicken. Also, post-surgical scar tissue can also interfere with proper wrist and nerve function contributing to more pressure on the nerve.
