The effect of long-term poor sleep quality on risk of back-related disability and the modifying role of physical activity

Abstract Sleep problems and regular leisure time physical activity (LTPA) are interrelated and have contrasting effects on risk of back pain. However, no studies have investigated the influence of long-term poor sleep quality on risk of back-related disability, or if LTPA modifies this association....
