The effects of osteopathic manipulative treatment on pain and disability in patients with chronic neck pain: A single-blinded randomized controlled trial.

The control group received no treatment at all, so the trial cannot show that OMT is better than another hands-on treatment, exercise, or usual care. There was no long-term follow-up, which the authors call a major limitation. What is reported is the state right after 3 to 4 sessions. Carryover effects were found in the main outcomes, so only the first phase of the cross-over was analysed. Half of each participant's data, and the cross-over comparison itself, went unused. Because of how visits were scheduled, the OMT group was re-assessed about 5 days later than the waiting group (5.2 weeks versus 4.4 weeks on average), so they had longer to improve. Participants were recruited by advertisement from the general population and were not necessarily seeking care for their neck pain. People who come to a clinic might respond differently. Randomisation happened before the baseline assessment, which pushed the dropout rate up to 23%. The authors say the other order would have given 14%. It was a single centre, and the trial was designed and powered to validate head-neck motor control tests, not to test these patient-reported outcomes. It could detect an effect size of 0.53 or larger, so smaller benefits would have been missed. The sample averaged just over 40 years old with pain lasting more than 8 years and was mostly female, so it says little about older patients or people with more recent injuries.

Do not read this as showing that osteopathic manipulation beats the manual therapy or exercise you already provide. The comparison was an untreated waiting period, the OMT group was assessed about 5 days later than the control group, and only 3 to 4 sessions were given with no long-term follow-up. The average gain was about 1 point of pain out of 11.
