Prevalence of sleep disturbance in patients with cervical radiculopathy and an analysis of risk factors: a cross-sectional study.

OBJECTIVE

Previous research has shown that many patients with musculoskeletal diseases suffer from sleep disturbances. However, the sleep quality of patients with cervical radiculopathy (CR) has yet to be fully investigated. This study aims to investigate the prevalence and status of sleep disturbances in patients with CR and identify the mechanisms and risk factors associated with this condition.

METHODS

We conducted a cross-sectional study of patients diagnosed with CR. The Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were used to evaluate the sleep quality of patients and determine whether patients experience sleep disturbances. In addition, we analyzed the clinical and radiological risk factors of sleep disturbance and determined the key risk factors related to sleep disturbance by multivariable analysis.

RESULTS

According to specific inclusion and exclusion criteria, 186 patients with CR were finally included, with a mean age of 59.1 ± 14.3 years, of which 113 (60.8%) were female. Sleep disturbance was defined as a PSQI score ≥ 6 and was identified in 56.5% of patients (105/186). By performing multivariate analysis, we determined that sleep disturbance was closely related to the female gender, a higher Beck Depression Inventory (BDI) score, a reduction in cervical mobility, an increase in C2-C7 sagittal vertical axis (C2-C7 SVA), and severe asymmetry of the paravertebral muscle at C5 and C6 levels.

CONCLUSION

In this study, we identified the high prevalence and potential high-risk factors of sleep disturbance in patients with CR. Clinicians should closely evaluate and monitor such patients and consider appropriate treatment strategies.
