The purpose of this study is to demonstrate the effects of low power laser irradiation on the superficial radial sensory nerve conduction. Both forearm of twenty three healthy adults were irradiated helium-neon and infrared laser by Helium-Neon 12 Combi Scanner(Felas co.). Average intensity was 23mW, irradiance was 23 mW/cm² and fluence was 0.69 J/cm²-13.8 J/cm². No significant changes were noted among pre-laser test, during laser test(1 min, 5 min, 10 min) and post-laser test(after 5 min, 60 min) in the superficial radial sensory nerve conduction (latency, amplitude, duration). We concluded that applied intensity of helium-neon and infrared laser irradiation in our laboratory wasn't alter conduction of superficial radial sensory nerve conduction study in normal adults.
