Laser irradiation therapy in carpal tunnel syndrome

ABSTRACT

The study was carried out on 28 cases recommended for surgery. Sensory latency and sensory nerve conduction velocity were measured for the median nerve before and after every five sittings through a 20 sittings course of laser therapy. A decrease in the sensory latency values was observed for 64 percent of the individuals treated by laser irradiation. An optimal dose value of irradiation was observed after the fifth sitting of 20 minutes duration. An increase in sensory conduction velocity measurements was noticed for 68 percent of cases after the twentieth sitting. This study suggests that the laser irradiation partially relieves the nerve entrapment in more than 64 percent of patients, probably through its thermal and bio-stimulatory vasodilatation effect
