CARPAL TUNNEL SYNDROME: A REVIEW

This research reviews carpal tunnel syndrome. Carpal tunnel syndrome in a medical context is a nerve entrapment disorder (Carpi, 1989). The tendons connecting the fingers to arm muscles pass through a small opening in the wrist, and they are surrounded by synovial sheaths. The synovial sheaths are thin, fluid-filled sacs, which swell when the tendons are overused. The swelling squeezes the median nerve against the wrist bone, or carpal ligament. The wrist is a freely movable joint in which the carpal bones glide across one another. Movement of the bonds is restricted by ligaments. The median nerve provides sensation to the entire hand, and pressure on the nerve causes pain. Presenting symptoms include paresthesias and weakness in the territory of the median nerve (Rakel, 1991). Carpal tunnel syndrome includes symptoms of pain, numbness, and weakness in the muscles that are enervated by branches of the median nerve (American Medical Association, 1989). Early complications of carpal tunnel syndrome include chronic peritoneal dialysis and hemodialysis (Bickness, 1991).

Diagnosis of carpal tunnel syndrome may occur through a variety of procedures. The measurement of differences in sensory conduction and velocity between different sensory branches and segments of the median and ulnar nerves is one such procedure (Joynt, 1989). Measurement o

environment. It must continually change and adapt to the environment. Open systems require information input, negative feedback, and a coding process. Without negative feedback, a system's steady state vanishes, its boundaries disappear, and the system dies. A person is an individual behavioral system. For individuals, the external environment includes all forces (objects, events, and situations) which are capable of impinging on the individual. For individuals, the internal environment involves the psychological and physical characteristics of the individual which permit and facilitate reaction and adjustment to external forces, which include the family system. Behavioral system balance within a family is a manifestation of successful adjustments and adaptations, even though observed behavior may not appear to be consistent with accepted cultural or biologic norms for healthy behavior. Living systems can and do operate at varying levels of effectiveness and efficiency, but, to be able to operate at all, some minimum level of balance, both internally and externally, must be maintained. A behavioral system possess sufficient flexibility to react effectively to usual variations in the forces acting upon it, and it possess
