Carpal Tunnel Pain and Chiropractic Treatment
Introduction
Carpal Tunnel Syndrome falls into the category of neurological conditions referred to as nerve entrapment disorders and is clearly the most prevalent of these disorders. As the name infers, 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 travels on its way to energize and animate the hand and fingers. In addition to the median nerve, the carpal tunnel is comprised of the nine tendons of the forearm muscles that are responsible for bending and flexing of the fingers and thumb. There are also arteries and lymphatic vessels that supply circulation to the hand located within the tunnel. The bottom and sides of this tunnel are formed by wrist bones and the top of the tunnel is covered by a strong band of connective tissue called the transverse carpal ligament. The carpal tunnel is a densely-packed space about the size of an index finger. The flexor tendons, arteries and median nerve are designed to glide easily 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 dimenishes due to a mechanical dysfunction of the carpal bones, the median nerve can become constricted or entrapped by the carpal tunnel. The initial symptoms of carpal tunnel syndrome usually include pain, numbness, paraesthesia (pins and needles) and tingling in the fingers and hands especially the thumb and adjacent two fingers. The symptoms are markedly apparent at night, often awakening the sufferer from sleep and making it necessary for the person to “shake out” or rub the hands in an attempt to relieve the unpleasant sensations. In addition, activity can cause the hands to feel awkward or weak, and fatigue easily. Over time, the ability to hold small objects using the thumb and fingers can be affected dramatically and if left untreated, can lead to total dysfunction of the hand.
Some accepted causes and associated conditions are:
- 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 instrumental in contributing to the symptoms of 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
Proper diagnosis and management of this condition is essential in order to curtail the disabling symptoms associated with the advancement of CTS. Your Ventura Chiropractor has many years of experience in this area. Chiropractors are well-trained in treating CTS. In addition to chiropractic adjustments of the wrist joints, treatment by chiropractor may include inflammation reduction therapy such as ultrasound or low level laser. Electromusclestim can often help to strengthen the weak muscles of the forearm and soft tissue massage is effective in stretching contracted tissues. You might be advised to wear a splint or support, particularly at night, to aid in the decompression of the carpal tunnel. Your Ventura Chiropractor will also give you specific exercises to stretch and/or strengthen muscles of the forearm and hand.
