Carpal Tunnel Relief 'Is Exercise the Solution?
Carpal tunnel Syndrome (CTS) is one of many musculoskeletal injuries listed under the broader terms of Repetitive Strain Injury (RSI) or Cumulative Trauma Disorder (CTD). A number of other injuries listed under these terms, but that are not exclusively caused by a repetitive strain injury or cumulative trauma disorder, include Guyon's Syndrome, Tendonitis, Cubital Tunnel Syndrome, Epicondylitis and Trigger Finger.
Carpal tunnel syndrome and other types of repetitive strain injuries are most often caused by excessive overuse of a muscle or group of muscles in a unidirectional (One way) movement pattern. Examples would include typing, wringing a washcloth and using a computer mouse. All of the movement patterns involve motion against resistance in one direction 'flexion. This one-way motion does not actually have to involve "repetitive" movements as the term "repetitive strain injury" implies, as it is just as common for an individual to become afflicted with a repetitive strain injury while performing activities that involve no movement of the hands at all. Examples of this would include holding onto a steering wheel, gripping a pen or a tool such as a hammer all day. With these types of activities, no repetitive type motion is involved at all, but instead, "static flexion" is utilized, which involves the overuse of these muscles, but in a manner that is stationary.
Since Repetitive strain injuries are most often caused by unidirectional movement patterns, the best way to counteract each specific overused motion is the implementation of an exercise program that involves resistance exercises for the opposing muscle or group of muscles that is being overused. An example training program for carpal tunnel syndrome would include resistance exercises for the muscles that open (extension) the hands in order to counteract the overuse of the muscles that close the hands (flexion). This principal of "balancing" muscles groups so that there is a more natural equality of strength between muscles that surround a specific joint, whether it is the wrist, elbow, shoulder or neck, is basic common sense and integrated into training programs by the top practitioners and therapists in the industry today.
Here are a few examples of practitioner responses regarding the implementation of restoring balance between muscle groups in order to prevent and rehabilitate repetitive strain injuries including Carpal tunnel syndrome.
"Muscle balance must be restored with specific exercises. Otherwise, the already strong and overused muscles get stronger, and the weak and underused muscles remain weak. Individuals get good at using the overused muscles and must be trained specifically to recruit and strengthen the weak underused muscles." Philip E. Higgs, M.D. and Susan E. Mackinnon, M.D. Department of Surgery, Washington University School of Medicine, St. Louis, Missouri. Annu. Rev. Med. 1995. 46:1-16
"If certain muscle groups are underused, opposing muscle groups will be overused. Muscles in either a lengthened or shortened position will be at a mechanical disadvantage and weak. The overused group will hypertrophy, and the underused group will continue to be weak. This combination produces a self perpetuating condition that maintains the abnormal posture and muscle imbalance." Philip E. Higgs, M.D. and Susan E. Mackinnon, M.D. Department of Surgery, Washington University School of Medicine, St. Louis, Missouri. Annu. Rev. Med. 1995. 46:1-16
A strong example of how important it is to properly balance muscle groups is seen in the following statement regarding the balancing of the in the hands and forearms.
"All of the extrinsic hand muscles become involved in a power grip, in proportion to the strength of the grip."........ "Strong agonist-antagonist interactions are needed between the flexors and extensors of the hand and fingers to produce forceful hand-grip. Powerful flexion of the distal phalanges requires strong activity also of the finger extensors." Janet G. Travell, M.D. and David G. Simons, M.D. Myofascial Pain and Dysfunction-The Trigger Point Manual. Volume1 Upper Extremities, Ch:35, pg. 501. Copyright 1983.
Performing corrective exercises in order to prevent and rehabilitate carpal tunnel syndrome and repetitive strain injuries is of the utmost importance. In 95% of most cases, there is no need for invasive techniques like cortisone injections or surgery in order to eliminate carpal tunnel or other repetitive strain injuries. It is one thing if you have an actual structural anomaly that needs to be corrected, but since most cases of carpal tunnel and repetitive strain occur in later years, it is quite obvious that a physical anomaly does not exist as this would be experienced by the individual in their younger years. Instead a structural or joint imbalance exists that has developed due to long-term overuse or sudden trauma due to overuse, and is a result of overly strong muscles pulling one direction while the opposing weak muscles try unsuccessfully to counteract and pull the other direction.
Muscle imbalances can be corrected with simple exercises. Below is a chart showing the activity that can cause the muscle imbalance and which muscles need to be stretched and which ones need to be strengthened in order to eliminate the symptoms associated with carpal tunnel syndrome. By performing an active exercise program that focuses on keeping muscles balanced, individuals can stay healthy and pain-free!
Be sure to be aware of any pain that is experienced 'while' performing exercises. If pain is experienced while performing exercises, stop immediately. Post exercise soreness is normal. Always be sure to consult a physician before beginning an exercise program.
