The human arm has three major nerves called the –Ulnar, Radial and Median nerves. These are well supported with flexor tendons and arteries and the wrist bones. The wrist bones are also called the ‘carpal bones’. The median nerve is allowed in to the wrist bones through a tough membrane called the ‘transverse carpal ligament’. The enclose space is thus termed as ‘the carpal tunnel’. The passage of this tunnel is relatively small and any blockage or any inflammation causes a severe pressure on the middle nerve –the median nerve. This is also called the entrapment of the nerve.
The condition largely entraps individuals in the age group of 30 to 60 years. It is five times more common in women than men. It affects ten percent of the population. The actual cause of the disease is unknown due to no specific response to the lab-tests. .The other conditions which are related to this disorder are pregnancy, premenstrual syndrome (PMS), Menopause, hypothyroidism, multiple myeloma, obesity, tuberculosis, and hypertension (high blood pressure). Any sort of injury or recurring wounds and injuries in the wrist area could also result in to the carpal tunnel syndrome. The carpel tunnel syndrome becomes more severe as one reaches his or her old age. These generally seem to attack medical complications like that of the arthritis, rheumatoid arthritis and severe diabetes also.
The Tingle’s sign: Pain experienced on tapping the median nerve on the wrist.
Phalen’s test: Numbness and weakness even the wrist is elongated for more than sixty seconds. The techniques of Electromyography and nerve conduction velocity are more specific and determined. The wrist X-rays are functional wrist scans to keep away any arthritis. The physician may sense the stress in the wrist. The electrical conduction of the nerve plexus is checked and the functioning of the tendons and ligaments. The medications and surgical methods are a cure of the disorder. The treatment would largely depend on the severity of the disorder. In majority of the cases which exhibit nil nervous response or partial paralysis surgical operations is a must. Otherwise, certain yoga exercises and self-help techniques are the cue.
