Double-blind study of the efficacy of laser therapy

The results of lasertherapy with infrared laser radiation in treatment of patients with locomotory system diseases associated with pain and limited mobility are discussed. The patients were divided into two groups. One group obtained lasertherapy. Average duration of the treatment was two weeks in everyday sessions which were 10 minutes long. The average dose of applied laser radiation was 2J/cm2. The second group underwent also lasertherapy but the laser diode was in non-operating mode. However, both patient as will as the therapeutists did not know that the laser does not operate as usual. The positive result regarding the mobility in 79.4 percent of patients were observed and regarding pain in 90.3 percent for the group treated by operating laser. In the control group the corresponding results were 59.3 percent and 62.5 percent.
