In a recent study on tension headache, researchers did ten sessions of laser acupuncture three times per week on one group and a similar placebo (dummy laser) treatment on another. The results revealed laser acupuncture to significantly relieve the symptoms of the real laser acupuncture group, while the placebo group did not improve as much.
