A double-blind controlled test was performed to determine the analgesic effect of semiconductor laser irradiation (30mW, Ga-Al-As semiconductor laser) on various types of low back pain.In the laser irradiated group, the improvement rate (including extremely effective and effective cases) of spontaneous pain was 61%, tenderness 61.8%, and locomotion pain 64% with an overall improvement rate of 73.5%. Significant differences from the control group were thus found in all types of pain (P<0.01).No significant difference was found in the Lasegue sign and Deep Tendon Reflex (DTR) between the laser irradiated group and the control group and no organic change was found in the laser irradiated tissues.Also, no significant difference was found between the laser irradiated group and control group blood test items with no side effect or degenerative changes. This confirmed that the laser irradiation was harmless to human tissues. The effectiveness and safety of the semiconductor low energy laser have been established. The authors therefore believe that the laser irradiation will be quite useful in treating low back pain in the future.
