Introduction

Carpal Tunnel Syndrome is the most common nerve entrapment disorder. As the name implies, these conditions come about when a nerve is trapped or constricted between other tissues of the body causing irritation and dysfunction of the nerve.

Anatomy

The carpal tunnel is embedded within the underside of the wrist. It is a tunnel, or passage, through which the Median nerve journeys on its way to energize and animate the hand and fingers. In addition to the median nerve, the carpal tunnel contains the nine tendons of the forearm muscles that are responsible for bending and flexing of the fingers and thumb. Also within the tunnel are arteries and lymphatic vessels that deliver circulation to the hand. The bottom and sides of this tunnel are formed by wrist bones and the top of the tunnel is covered by a heavy band of connective tissue called the transverse carpal ligament. The carpal tunnel is a thickly-packed space about the size of an index finger. The flexor tendons, arteries and median nerve are intended to glide without friction past each other during wrist and finger movement.

If the size of the tendon enlarges due to irritation or overuse, or if the carpal tunnel size shrinks because of  an improper use of the carpal bones, the median nerve can become squeezed or entrapped by the carpal tunnel. The early symptoms of carpal tunnel syndrome as a general rule include pain, numbness, paraesthesia (pins and needles) and tingling in the fingers and hands especially the thumb and adjacent two fingers.  These symptoms are especially noticeable in the night and often wake people from their sleep as the individual has to sit up in bed and shake-out and/or rub the hands in order decrease these unpleasant feelings.  In addition, activity can cause the hands to feel clumsy or weak, and fatigue easily. Over time, the ability to grasp small objects using the thumb and fingers can be affected dramatically and if left untreated, can lead to total dysfunction of the hand.

The following are general causes and corresponding conditions:

• repetitive and forceful grasping with the hands

• prolonged computer usage especially with poor wrist position

• activities that require repetitive bending of the wrist

• broken or dislocated bones in the wrist which produce swelling

• arthritis, especially the rheumatoid type

• thyroid gland imbalance

• sugar diabetes

• hormonal changes associated with menopause or pregnancy

Though any of the causes and conditions listed can be partly responsible for Carpal Tunnel Syndrome, often the actual root cannot be found. However, people who perform jobs that require use of vibration tools and machinery, and/or work in extreme temperatures are often subjected to this condition.  In addition, repetitive housework as seemingly inconsequential as wringing clothes by hand, can bring on carpal tunnel symptoms. However, the continuing increase in computer use is the most compelling explanation for the number of individuals who are suffering with Carpal Tunnel Syndrome today. This is becoming a major concern in the developed world where people of all ages are spending much of their time typing on a keyboard & clicking on a mouse.

Treatment

Competent diagnosis and treatment is vital to relieving the painful and debilitating symptoms of CTS. Your Ventura Chiropractor is highly skilled in the diagnosis and managment of CTS. Chiropractors are equipped to deal with this problem and can offer many sufferers with relief.  Treatment by chiropractor can include ultrasound or low level laser to help reduce inflammation, electro therapy to strengthen weak muscles of the forearm, soft tissue massage to stretch contracted tissues and, of course, adjustments of the dysfunctional joints of the wrist. You might be advised to wear a splint or support, especially at night, to help retain the wrist in a neutral position to decompress the carpal tunnel. Your Ventura Chiropractor will also give you specific exercises to stretch and/or strengthen muscles of the forearm and hand.
