Your wrist has eight bones called the carpal bones. Through the wrist run 9 muscle tendons, 3 nerves, arteries and veins. They are held in place by a strong ligamentous band called the retinaculum.
Repetitive motion activities such as working with a computer, key punch, tools, etc can cause an inflammation of the retinaculum and in turn cause pain, tingling, numbness and a weakness in the hand, a condition known as Carpal Tunnel Syndrome.
The condition responds well to a diversified extremity adjusting technique, cold laser therapy, ultrasound and interferential.
