UK based researchers report in The Journal of Pain that a study of primary care patients who sought treatment for low back pain found that high pain intensity is predictive of future chronic pain, even after five years. This study is the first to show this connection over a long time period. Clinically, the study confirms that effective pain relief in the initial management of low back pain has implications for long term improvement. Patient beliefs that pain will persist a long time can also predict progression to clinically significant low back pain. Read a news report here.
