The purpose of the present study was to validate the Functional Shoulder Score (FSS), a new patient-reported outcome score specifically designed to evaluate patients with rotator cuff disorders.
One hundred and nineteen patients were assessed using two shoulder scoring systems [the FSS and the Constant-Murley Score (CMS)] at 3 weeks pre- and 6 months post-arthroscopic rotator cuff surgery. The reliability, validity, responsiveness and interpretability of the FSS were evaluated.
Reliability analysis (test-retest) showed an intraclass correlation coefficient value of 0.96 [95% confidence interval (CI) = 0.92 to 0.98]. Internal consistency analysis revealed a Cronbach's alpha coefficient of 0.93. The Pearson correlation coefficient FSS-CMS was 0.782 pre-operatively and 0.737 postoperatively (p < 0.0005). There was a statistically significant increase in FSS scores postoperatively, an effect size of 3.06 and standardized response mean of 2.80. The value for minimal detectable change was ±8.38 scale points (based on a 90% CI) and the minimal clinically important difference for improvement was 24.7 ± 5.4 points.
The FSS is a patient-reported outcome measure that can easily be incorporated into clinical practice, providing a quick, reliable, valid and practical measure for rotator cuff problems. The questionnaire is highly sensitive to clinical change.
本研究的目的是验证功能肩部评分（FSS），这是一种专门为评估肩袖损伤患者而设计的新的患者报告结局评分。
119例患者在关节镜下肩袖修复术前3周和术后6个月使用两种肩部评分系统[FSS和Constant-Murley评分（CMS）]进行评估。对FSS的可靠性、有效性、反应性和可解释性进行了评估。
可靠性分析（重测）显示组内相关系数值为0.96[95%置信区间（CI）=0.92至0.98]。内部一致性分析显示Cronbach's alpha系数为0.93。术前FSS与CMS之间的Pearson相关系数为0.782，术后为0.737（p<0.0005）。术后FSS评分有统计学显著增加效应量为3.06，标准化反应均值为2.80。最小可检测变化值为±8.38个量表点（基于90%CI），改善的最小临床重要差异为24.7±5.4分。
FSS是一种患者报告结局指标，可轻松纳入临床实践，为肩袖问题提供快速、可靠、有效且实用的测量方法。该问卷对临床变化高度敏感。
