Restoration of sleep is reported to be strongly associated with better physical, cognitive and psychological well-being. Sleep quality is often found to be compromised in individuals with LBP, specifically in chronic LBP. As chronic LBP is found to be associated with decreased functional ability, depression, anxiety and quality of life, disturbance in sleep is also strongly associated with these symptoms. These symptoms have also been shown to influence pain perception. However, a majority of the studies do not delineate the causal relationship between sleep quality and its impact on chronic LBP; although one study reports sleep disturbance is a risk factor for LBP in adolescent girls. Only one review have discussed the relationship of sleep and chronic LBP, and no review to date has examined the interrelationship of sleep quality, function, pain intensity, psychological factors, and quality of life in individuals with LBP. As poor sleep quality is a major concern among patients with chronic LBP, exploring its impact on pain, function and quality of life is critical to enable researchers in formulating guidelines for patient care and improving our knowledge of sleep disturbance in earlier stages of LBP. Hence, this article explores the impact of sleep quality on individuals with LBP in terms of perception of pain intensity, functional ability, anxiety, depression and quality of life.
