The Correlation between Shoulder Pathologies and Sleep Disturbances
2Faculty of Medicine, Technion, Israel
Background:
In this study, we sought to assess and characterize the correlation between shoulder pathologies and sleep disturbances.
Patients and Methods:
106 participants were divided into two groups. All participants completed the ISI (Insomnia Severity Index) questionnaire, in addition to questions related to participant demographics, health status, medication, and other known insomnia risk factors.
Results:
Patients with shoulder pathologies accumulated more points in the questionnaire than control group (M=18.33, SD±7.1 vs M=6.20, SD±5.56, respectively). The shoulder pathology group suffered more from severe insomnia in the ISI questionnaire (t(104=-9.88 P<0.001), even after correcting for cofounders (t(56.4)=-8.25 P<0.001). In addition, the shorter the duration of shoulder pathology, the more severe we found the insomnia to be (b=-0.38, p<0.05). Patients with shoulder pathology along with other comorbidities suffered from more sleep disturbances than those who had a shoulder pathology without comorbidities (b=0.30, p<0.05). Lastly, the shoulder pathology group was at a higher risk of having sleep disturbances as compared to the control group (RR=2.3, CI=1.6-3.3).
Discussion:
Sleep disturbances are more common among patients suffering from shoulder pathologies. A shorter duration of pathology and comorbidities may predict more severe sleep disturbances.
