Carpal tunnel syndrome (CTS) is the most expensive of all work-related injuries. Over his or her lifetime, a carpal tunnel patient loses about $30,000 in medical bills and time absent from work. CTS typically occurs in adults, with women 3 times more likely to develop it than men.

The dominant hand is usually affected first, and the pain is typically severe. CTS is especially common in assembly-line workers in manufacturing, sewing, finishing, cleaning and similar industries.
What is CTS?

CTS is a problem of the median nerve, which runs from the forearm into the hand. CTS occurs when the median nerve gets compressed in the carpal tunnel—a narrow tunnel at the wrist—made up of bones and soft tissues, such as nerves, tendons, ligaments, and blood vessels. The compression may result in pain, weakness, and/or numbness in the hand and wrist, which radiates up into the forearm. CTS is the most common of the “entrapment neuropathies”—compression or trauma of the body’s nerves in the hands or feet.
What are the Symptoms?

Burning, tingling, itching, and/or numbness in the palm of the hand and thumb, index, and middle fingers are most common. Some people with CTS say that their fingers feel useless and swollen, even though little or no swelling is apparent. Since many people sleep with flexed wrists, the symptoms often first appear while sleeping. As symptoms worsen, they may feel tingling during the day. In addition, weakened grip strength may make it difficult to form a fist or grasp small objects. Some people develop wasting of the muscles at the base of the thumb. Some are unable to distinguish hot from cold by touch.
Why Does CTS Develop?

Carpal tunnel syndrome is often the result of a combination of factors that increase pressure on the median nerve and tendons in the carpal tunnel, rather than a problem with the nerve itself. Most likely the disorder is due to a congenital predisposition - the carpal tunnel is simply smaller in some people than in others. Other contributing factors include trauma or injury to the wrist that cause swelling, such as sprain or fracture; overactivity of the pituitary gland; hypothyroidism; rheumatoid arthritis; mechanical problems in the wrist joint; work stress; repeated use of vibrating hand tools; fluid retention during pregnancy or menopause; or the development of a cyst or tumor in the canal. In some cases no cause can be identified.
What is the Treatment for CTS?

Initial therapy includes:
• Resting the affected hand and wrist
• Avoiding activities that may worsen symptoms
• Immobilizing the wrist in a splint to avoid further damage from twisting or bending
• Applying cool packs to help reduce swelling from inflammations

Some medications can help with pain control and inflammation. Studies have shown that vitamin B6 supplements may relieve CTS symptoms.

Chiropractic joint manipulation and mobilization of the wrist and hand, stretching and strengthening exercises, soft-tissue mobilization techniques, and even yoga can be helpful. Generally, low force chiropractic adjusting, combined with some simple wrist muscle stretching and strengthening will make huge strides toward pain reduction. Scientists are also investigating other therapies, such as acupuncture, that may help prevent and treat this disorder.

Occasionally, patients whose symptoms fail to respond to conservative care may require surgery. The surgeon releases the ligament covering the carpal tunnel. The majority of patients recover completely after treatment, and the recurrence rate is low. Proper posture and movement as instructed by your doctor of chiropractic can help prevent CTS recurrences.
