Low-back pain is one of the most common and costly musculoskeletal problems in modern society. About 80% of the population will experience low-back pain at some time in their lives. Many people with low-back pain seek the care of a chiropractor. For this review, chiropractic was defined as encompassing a combination of therapies such as spinal manipulation, massage, heat and cold therapies, electrotherapies, the use of mechanical devices, exercise programs, nutritional advice, orthotics, lifestyle modification and patient education. The review did not look at studies where chiropractic was defined as spinal manipulation alone as this has been reviewed elsewhere and is not necessarily reflective of actual clinical practice. Non-specific low-back pain indicates that no specific cause is detectable, such as infection, cancer, osteoporosis, rheumatoid arthritis, fracture, inflammatory process or radicular syndrome (pain, tingling or numbness spreading down the leg).Twelve randomised trials (including 2887 participants) assessing various combinations of chiropractic care for low-back pain were included in this review, but only three of these studies were considered to have a low risk of bias.
The review shows that while combined chiropractic interventions slightly improved pain and disability in the short term and pain in the medium term for acute and subacute low-back pain, there is currently no evidence to support or refute that combined chiropractic interventions provide a clinically meaningful advantage over other treatments for pain or disability in people with low-back pain. Any demonstrated differences were small and were only seen in studies with a high risk of bias. Future research is very likely to change the results and our confidence in them. Well conducted randomised trials are required that compare combined chiropractic interventions to other established therapies for low-back pain.
