The latest volume of the Annals of Internal Medicine features a randomised controlled trial that compared the effectiveness of two types of massage for chronic low back pain. The trial found that massage may be effective with benefits lasting at least 6 months. Randomization was computer-generated, with centralized allocation concealment. Participants were blinded to massage type but not to assignment to massage versus usual care. Massage therapists were unblinded. The study personnel who assessed outcomes were blinded to treatment assignment. The abstract and the full article are available for free at:
