INTRODUCTION: The literature is unanimous in saying that shoulder pain, due to rotator cuff tear (RCT), may be mostly at night; to our knowledge, this statement is not supported by scientific evidence. Our aim was to investigate sleep quality and disturbances in patient with RCT and in a control group. MATERIALS AND METHODS: A case-control design study was used. We enrolled 324 consecutive patients (Group A) (156M-168F, mean age ± SD: 64.94 ± 6.97; range 47-74) who underwent arthroscopic rotator cuff repair. Tear size was determined intraoperatively. The control group (Group B) included 184 subjects (80M-104F, mean age ± SD = 63.34 ± 6.26; range 44-75) with no RCT. All participants were submitted to two standardized self-reported questionnaires evaluating sleep quality and disturbances: the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS). Data were submitted to statistics. RESULTS: We found no significant differences between the two groups according to both PSQI (Group A: 5.22 ± 2.59; Group B: 5.21 ± 2.39) and ESS (Group A: 2.59 ± 2.54; Group B: 5.76 ± 2.63), p > 0.05. Patients with small tears had average PSQI and ESS higher than patients with large and massive lesions (p < 0.005). Pearson's test showed that tear severity was negatively correlated with both sleep latency (r 2 = -0.35, β = 0.069, p < 0.005) and sleep disturbances (r 2 = -0.65, β = 0.053, p < 0.001). CONCLUSIONS: RCT is only one of the responsible causes for sleep disturbance in middle-aged and elderly subjects. Patients with small tears have a poorer sleep quality with respect to those with a more severe tear; particularly, they not only take more time to fall asleep, but also have a more disturbed sleep compared to patients with large and massive tears.

Abstract
INTRODUCTION: The literature is unanimous in saying that shoulder pain, due to rotator cuff tear (RCT), may be mostly at night; to our knowledge, this statement is not supported by scientific evidence. Our aim was to investigate sleep quality and disturbances in patient with RCT and in a control group. MATERIALS AND METHODS: A case-control design study was used. We enrolled 324 consecutive patients (Group A) (156M-168F, mean age ± SD: 64.94 ± 6.97; range 47-74) who underwent arthroscopic rotator cuff repair. Tear size was determined intraoperatively. The control group (Group B) included 184 subjects (80M-104F, mean age ± SD = 63.34 ± 6.26; range 44-75) with no RCT. All participants were submitted to two standardized self-reported questionnaires evaluating sleep quality and disturbances: the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS). Data were submitted to statistics. RESULTS: We found no significant differences between the two groups according to both PSQI (Group A: 5.22 ± 2.59; Group B: 5.21 ± 2.39) and ESS (Group A: 2.59 ± 2.54; Group B: 5.76 ± 2.63), p > 0.05. Patients with small tears had average PSQI and ESS higher than patients with large and massive lesions (p < 0.005). Pearson's test showed that tear severity was negatively correlated with both sleep latency (r 2 = -0.35, β = 0.069, p < 0.005) and sleep disturbances (r 2 = -0.65, β = 0.053, p < 0.001).
