This book draws together recent results and ideas from most of the leading UK researchers into back pain. The emphasis is on disorders of the lumbar spine, their pathogenesis, diagnosis and treatment. This is in contrast to most books on the spine which either concentrate on the normal spine or deal with a specialised approach such as surgery. By drawing together contributions from a wide range of clinical and scientific backgrounds, including alternative therapies such as osteopathy and chiropractice, the problem of low back pain is shown to be complex and multifactorial.
