Study designs of evaluations included in the review
The included studies were clinical trials on the use of homeopathy for reducing DOMS in human volunteers, which contained a control group receiving placebo. The trials were conducted under double-blind conditions.
Specific interventions included in the review
Placebo versus Rhus toxicodendron (D2 to D8), Rhus toxicodendron D4, Arnica (D2 to D8), Arnica montana D30, Arnica montana 30C plus Rhus toxicodendron, and Arnica montana 30C plus Rhus toxicodendron plus sarcolactic acid 30C. These were taken for one day prior to exercise, for 6 to 7 days post-exercise, or for one day prior to exercise then continued after exercise until cessation of soreness.
Participants included in the review
The participants were healthy volunteers who underwent some form of exercise to induce DOMS.
Outcomes assessed in the review
The outcomes assessed were: soreness intensity (rating scale) and duration; maximal isometric muscle strength; blood tests and serum creatine kinase concentrations; mean muscle soreness during 5 post-exercise days; the number of symptom-free days; maximum soreness score; the number of days to no soreness; and the number of days of no medication.
How were decisions on the relevance of primary studies made?
