Perception and use of complementary and alternative medicine for low back pain

To determine the prevalence of complementary and alternative medicine (CAM) use in patients with low back pain (LBP) and to identify its correlation with demographic factors, clinical condition and psychosocial factors.

A cross-sectional study was conducted with 278 LBP patients. Use of CAM, demographic parameters and disease duration were determined. Self-reported health status and self-rated scales assessed the effect of disease on quality of life and emotional well-being, respectively. Satisfaction with orthopaedic care and belief partiality towards CAM were assessed.

In all, 72.3% patients sought CAM treatment. The most common choice of CAM was traditional Chinese medicine (TCM; n = 166), followed by massage therapy ( n = 114) and chiropractic treatment ( n = 45). Within TCM, acupuncture was the most popular treatment for LBP ( n = 127). Only 32.5% patients informed their doctors of their CAM use. In univariate analyses, factors positively associated with CAM use included duration of LBP (odds ratio (OR) = 1.45, 95% confidence interval (CI): 1.06-1.97), use of CAM in close social circles (OR = 1.98, 95% CI: 1.15-3.43) and summary score for belief partiality towards CAM (OR = 1.18, 95% CI: 1.13-1.23). Variables negatively and significantly associated with status of CAM use include age (OR = 0.97, 95% CI: 0.95-0.99) and summary score for satisfaction with orthopaedic care (OR = 0.93, 95% CI: 0.88-0.99).

CAM use in patients with LBP is prevalent and largely unknown to their doctors. Personal beliefs and their satisfaction with conventional medical treatment both play a part in their decisions to use CAM. Future studies may aim at understanding the effect of CAM on patient adherence to conventional medical treatment and patients' perception of well-being and pain.
