A recent study appearing in the October 3, 2006 issue of Sleep Medicine looked at 26 subjects with obstructive sleep apnea. The subjects were randomly placed into three groups. One group received acupuncture. One group received “sham” acupuncture, which is superficial needling at points that are not acupuncture points. A third group did not receive treatment. The group receiving the acupuncture had improvements in the apnea-hyponea index and in the apnea index (50.5% and 79% respectively). They also had a decrease in the number of respiratory events (43%); the control group had a 53% increase in respiratory events.
