To assess and characterize the correlation between shoulder pathologies and sleep disturbances.
Participants enrolled into this case-control study were divided into two groups: patients with an established clinical diagnosis of active shoulder pathology (study group), and patients without any shoulder pathology (control group). All patients completed the Insomnia Severity Index (ISI) questionnaire, in addition to questions related to participant demographics, health status, medication, and other known insomnia risk factors.
A total of 98 patients were included (46 in the study group and 52 controls). Mean ISI score was significantly higher (indicating more severe insomnia) in the study group versus control group (t[96] = -9.67), even after correcting for confounders (t[53.1] = -8.61). Additionally, in patients with shoulder pathology, those with comorbidities experienced more sleep disturbances than those without comorbidities (β = 0.36). Lastly, the shoulder pathology group was at a higher risk of having sleep disturbances compared with controls (relative risk 4.86, 95% confidence interval 2.24, 10.55).
Sleep disturbances are more common among patients with shoulder pathologies. Comorbidities and a shorter duration of pathology may predict more severe sleep disturbances.
评估和描述肩部病变与睡眠障碍之间的相关性。
本病例对照研究纳入的参与者分为两组：有明确临床诊断的活跃肩部病变患者（研究组）和无任何肩部病变的患者（对照组）。所有患者均完成了失眠严重程度指数（ISI）问卷，此外还回答了与参与者人口统计学、健康状况、用药情况和其他已知的失眠危险因素相关的问题。
共纳入 98 例患者（研究组 46 例，对照组 52 例）。即使在调整混杂因素后（t[53.1] = -8.61），研究组的平均 ISI 评分仍明显高于对照组（t[96] = -9.67），表明失眠更严重。此外，在患有肩部病变的患者中，合并症患者的睡眠障碍比无合并症患者更严重（β=0.36）。最后，与对照组相比，肩部病变组发生睡眠障碍的风险更高（相对风险 4.86，95%置信区间 2.24，10.55）。
肩部病变患者更常出现睡眠障碍。合并症和较短的病变持续时间可能预示着更严重的睡眠障碍。
