RESUMO
Cupping Therapy (CT) is an ancient method and currently used in the treatment of a broad range of medical conditions. Nonetheless the mechanism of action of (CT) is not fully understood. This review aimed to identify possible mechanisms of action of (CT) from modern medicine perspective and offer possible explanations of its effects. English literature in PubMed, Cochrane Library and Google Scholar was searched using key words. Only 223 articles identified, 149 records screened, and 74 articles excluded for irrelevancy. Only 75 full-text articles were assessed for eligibility, included studies in this review were 64. Six theories have been suggested to explain the effects produced by cupping therapy. Pain reduction and changes in biomechanical properties of the skin could be explained by "Pain-Gate Theory", "Diffuse Noxious Inhibitory Controls" and "Reflex zone theory". Muscle relaxation, changes in local tissue structures and increase in blood circulation might be explained by "Nitric Oxide theory". Immunological effects and hormonal adjustments might be attributed to "Activation of immune system theory". Releasing of toxins and removal of wastes and heavy metals might be explained by "Blood Detoxification Theory". These theories may overlap or work interchangeably to produce various therapeutic effects in specific ailments and diseases. Apparently, no single theory exists to explain the whole effects of cupping. Further researches are needed to support or refute the aforesaid theories, and also develop innovative conceptualizations of (CT) in future.
RESUMO
BACKGROUND: One of the licensing requirements for cupping providers in Saudi Arabia is to attend a compulsory training course that lasts 5 days for non-physicians and 4 days for physicians, irrespective of any previous experience in cupping therapy. The course is conducted by the National Center of Complementary and Alternative Medicine (NCCAM/MOH). As a part of course auditing, the current study aimed to evaluate knowledge retention among licensed cupping providers 1-3 years after passing the official cupping course. METHODS: Licensed cupping providers were invited to attend a continuing medical education activity. Sixty-two attended the continuing medical education activity. Before the event, participants were asked to answer 35 multiple-choice questions taken from the same data bank as the pretest and posttest of the course. The test scores were linked and compared with the pre- and posttest of the training course. RESULTS: A paired t test showed significant differences between the pre- and posttest knowledge scores (mean difference: 224.6 ± 86, p = 0.0001) and between the posttest and follow-up knowledge scores (mean difference: -115.26 ± 103.9, p = 0.0001). The follow-up score was still significantly higher than the pretest score, with a mean difference of 112 (95% CI: 83.66-140.34, p = 0.0001). There was no significant effect of category (physician vs. non-physician) on knowledge retention after controlling for the postcourse score. Gender, the total duration of experience, and total years of experience in cupping did not affect knowledge score retention between the physicians and the non-physicians. CONCLUSION: The official cupping training course of the NCCAM/MOH achieved reasonable knowledge retention. To achieve long-term knowledge retention, refresher training/courses and continuous professional development will be required.
