Carpal Tunnel Syndrome is the most common nerve entrapment disorder. As the term “nerve entrapment” implies, these disorders happen when a nerve is trapped or compressed between body tissues creating inflammation and impairment of the nerve.
Anatomy
The carpal tunnel is situated in the underside of the wrist and is a passageway in which the median nerve travels through on its way to innervate the hand and fingers. In addition to the median nerve, the carpal tunnel includes 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. Wrist bones form the bottom and sides of the tunnel, while the top is shaped by the transverse carpal ligament, a strong band of connective tissue. The carpal tunnel is a densely-packed space about the size of an index finger. The flexor tendons, arteries and median nerve are intended 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 because of an improper use of the carpal bones, the median nerve can become compressed or entrapped within the carpal tunnel. At first, carpal tunnel symptoms generally include, pain, numbness, pins and needles, and tinging in the fingers and hand, particularly 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 lumpish or weak, and fatigue easily. Eventually, grasping small objects using the thumb and fingers can be gravely affected and, without treatment, can result in complete debilitation 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 contribute to carpal tunnel Syndrome, often the actual root cannot be found. Nevertheless, those who work with equipment that vibrates and/or perform their jobs in extreme temperatures often develop carpal tunnel symptoms. Even household activities as simple as repetitive wringing clothes by hand can help cause this syndrome. 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. I as, an Orlando chiropractor have 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. Your chiropractor may suggest that you wear a splint or support, particularly at night, to help retain the wrist in a neutral position to decompress the carpal tunnel. Your Orlando Chiropractor will also give you specific exercises to stretch and/or strengthen muscles of the forearm and hand.
