Chiropractic Effective for Hip Osteoarthritis
Some physical therapists and other health-care providers are firm believers in the efficacy of patient education as a means to reduce symptoms for various musculoskeletal diseases. Ongoing research has been conducted to investigate the actual effects that patient education has on symptoms.
In one such study, Danish researchers compared the effectiveness of patient education with chiropractic and patient education without chiropractic. The participants included patients with hip osteoarthritis. One group of patients were educated by a specially trained physical therapist; another group received the same education sessions in addition to manual therapy delivered by a chiropractor, including trigger point release therapy, muscular stretching, and joint manipulation. These two groups were also compared to a group receiving minimal control intervention, who performed simple home-based stretching exercises only.
Participants were treated for six weeks and rated their pain intensity following their specified interventions. Researchers also assessed participants for hip disability, pain outcomes, perceptions about their interventions, and whether or not hip replacement surgery was needed within a year.
The patient education group did not experience outcomes any better than the control group. But the patients who were educated in addition to being treated with chiropractic manual therapy had significant improvements compared to the other two groups. At six weeks, more than 76% of the chiropractic patients reported improvement compared to just 22% of the patient education group and 12% of the home-based stretching group. The chiropractic group was also significantly less likely to have hip replacement surgery within 12 months of the study. Only four in the chiropractic group needed an operation, in contrast with 12 patients in the patient education group and seven in the control group who needed surgery within the year.
Other research about hip osteoarthritis showed that chiropractic manual therapy alone provides effective treatment, and a follow-up study investigated the reason that chiropractic is so effective at easing hip pain.
