An investigation of sleep profiles in individuals with idiopathic scoliosis

OBJECTIVE: Sleep behaviors have not been well investigated in individuals with idiopathic scoliosis (IS). This study aimed to investigate sleep quality and daytime sleepiness in individuals with IS and investigate the relationship between sleep parameters and curve magnitude, trunk deformity severity, pain, and emotional status in adolescents with IS. MATERIAL AND METHODS: Ninety-one participants between the ages of 10 and 19 years with IS were included. Sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI), and daytime sleepiness was assessed with Epworth sleepiness scale (ESS). Pain was assessed using the short-form McGill pain questionnaire; the presence or severity of depressive feelings was evaluated using the Beck depression scale. RESULTS: The majority of the participants (64.8%) had poor sleep quality, while daytime sleepiness was within normal limits in most participants (85.7%).The frequency of participants without pain (52.7%) was similar to participants with pain (47.3%). The prevalence of participants with depressed mood was 35.2%. Participants with poor sleep quality were more likely to have a higher sensorial index (p<0.001), higher total pain scores (p=0.001), and less lumbar axial rotation (p=0.046). Higher pain (r=0.391), depression scores (r=0.234), and lower lumbar axial trunk rotation (r=-0.317) were associated with increased daytime sleepiness. CONCLUSION: We observed poor sleep quality and an association with pain in patients with IS. Curve magnitude had no adverse effect on sleep quality or daytime sleepiness. Therefore, the sleep profile and its association with pain should be considered during the rehabilitation process in patients with IS.
