Relationship between sleep, pain, and disability in patients with spinal pathology.

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±30 mm and 54±27 mm 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<.001), and ODI without the sleep component (r=.47, P<.001). Six of the subscales of PSQI were all also significantly correlated to ODI (.25
