A 2010 meta analysis reviewed a number of published studies to determine the strength of scientific evidence regarding the effectiveness of manual treatment for both musculoskeletal (MSK) and non-musculoskeletal (non-MSK) conditions.
Lead author Dr. Gert Bronfort reviewed 49 relevant systematic reviews and 16 evidence-based clinical guidelines and concluded that he and the other authors of the analysis found SMT/mobilization to be effective in adults for the following: acute, subacute, and chronic low back pain; migraine and cervicogenic headache; cervicogenic dizziness; and several extremity joint conditions. Interestingly, Dr. Bronfort and his team noted thoracic manipulation/mobilization as effective for acute and subacute neck pain, but the evidence available at the time was inconclusive for cervical manipulation/mobilization alone for neck pain of any duration.
The evidence was also inconclusive for SMT/mobilization for mid back pain, sciatica, tension-type headache, coccydynia, temporomandibular joint disorders, fibromyalgia, premenstrual syndrome, and pneumonia in older adults. Additionally, they found SMT/mobilization was not effective for asthma, dysmenorrhea (when compared to sham SMT), or stage 1 hypertension when added to an antihypertensive diet. In children, the evidence was inconclusive regarding the effectiveness of SMT/mobilization for otitis media and enuresis, and they also noted SMT/mobilization was not effective for infantile colic and asthma when compared with sham SMT.
In a 2014 follow-up study, lead author Dr. Christine Clar confirmed most of the previously “inconclusive” or “moderate” evidence ratings of the 2010 evidence report. However, the availability of new research motivated Dr. Clar to note moderate evidence for these conditions: manipulation/mobilization (with exercise) for rotator cuff disorders, spinal mobilization for cervicogenic headache, and mobilization for miscellaneous headache.
These two meta-analyses are significantly helpful for those considering chiropractic care for specific conditions. Reviews like this are planned for the future, and the list of conditions that respond well to chiropractic care should expand as areas that need further study are determined and more research is published.
