Relationship Between Sleep, Pain, and Disability in Patients With Spinal Pathology

Abstract Objective To characterize sleep and its relationship with disability and pain in patients with spine pathology. Design A survey study. Setting A university-based hospital spine clinic. Participants Subjects (N=121) with mixed-etiology spine pathology. Interventions Not applicable. Main Outcome Measures Self-reported disability (Oswestry Disability Index [ODI]), back and leg pain intensity, the effect of back or leg pain on function, and sleep (Pittsburgh Sleep Quality Index [PSQI]) assessments were completed. Results Severe disability was evident with a mean ODI ± SD of 54.9±14, with mean pain intensities ± SD of 50±30mm and 54±27mm of 100mm for the leg and back, respectively. The mean PSQI ± SD was 10.4±5.3, with 87% of participants scoring greater than the sleep-disordered threshold of 5. PSQI was correlated to ODI ( r =.53, P
