Annals of Internal Medicine, 07/11/2011
Cherkin DC et al. – Massage therapy may be effective for treatment of chronic back pain, with benefits lasting at least 6 months. No clinically meaningful difference between relaxation and structural massage was observed in terms of relieving disability or symptoms.Methods
- Parallel–group randomized, controlled trial.
- 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.
- An integrated health care delivery system in the Seattle area.
- 401 persons 20 to 65 years of age with nonspecific chronic low back pain.
- Structural massage (n = 132), relaxation massage (n = 136), or usual care (n = 133).
- The massage groups had similar functional outcomes at 10 weeks.
- The adjusted mean RDQ score was 2.9 points (95% CI, 1.8 to 4.0 points) lower in the relaxation group and 2.5 points (CI, 1.4 to 3.5 points) lower in the structural massage group than in the usual care group, and adjusted mean symptom bothersomeness scores were 1.7 points (CI, 1.2 to 2.2 points) lower with relaxation massage and 1.4 points (CI, 0.8 to 1.9 points) lower with structural massage.
- The beneficial effects of relaxation massage on function (but not on symptom reduction) persisted at 52 weeks but were small.
