Effect of helium-neon laser auriculotherapy on experimental pain threshold. 1990

C E King, and J A Clelland, and C J Knowles, and J R Jackson

This study was conducted to examine the effects of helium-neon laser auriculotherapy on experimental pain threshold. Eighty healthy female and male subjects, aged 18 to 39 years, were assigned randomly to one of two treatment groups. Subjects in the Experimental Group (n = 41) received laser stimulation, and subjects in the Control Group (n = 39) received sham stimulation to appropriate acupuncture points on the left ear. Experimental pain threshold at the ipsilateral wrist was determined with an electrical stimulus immediately before and after treatment. The mean change (posttreatment minus pretreatment) for the Experimental Group was greater than the mean change for the Control Group (p less than .05). The Experimental Group demonstrated a statistically significant (p less than .05) increase in mean pain threshold after treatment, but the Control Group did not. Results indicate that helium-neon laser auriculotherapy can increase experimental pain threshold and suggest a possible alternative for patients intolerant of transcutaneous electrical nerve stimulation.
