Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of three manual coccydynia treatments: a pilot study.
A prospective pilot study with independent assessment and a 2-year follow-up period was conducted. ⋯ There is a need for a placebo-controlled study to establish conclusively whether manual treatments are effective. This placebo must be an external treatment. A sample size of 190 patients would be required for 80% confidence in detecting a difference.

Randomized Controlled Trial Clinical Trial
Should we give detailed advice and information booklets to patients with back pain? A randomized controlled factorial trial of a self-management booklet and doctor advice to take exercise for back pain.
Randomized controlled factorial trial. ⋯ Doctors can increase satisfaction and moderately improve functional outcomes in the period immediately after the consultation when back pain is worst, by using very simple interventions: either by endorsing a self-management booklet or by giving advice to take exercise. Previous studies suggest that simple advice and the same written information provide reinforcement. This study supports evidence that it may not be helpful to provide a detailed information booklet and advice together, where the amounts or formats of information differ.
