Clinical measurement.
To cross-culturally adapt the Shoulder Pain and Disability Index (SPADI) into Brazilian Portuguese and to test the measurement properties of the Brazilian Portuguese versions of the SPADI, the short form of the Disabilities of the Arm, Shoulder and Hand, the Patient-Specific Functional Scale, a numeric pain rating scale, and the Global Perceived Effect scale in patients with shoulder disorders.
Most instruments for shoulder disorders were developed in English. For their use in Brazil, translation into Brazilian Portuguese, cross-cultural adaptation, and testing of measurement properties of these instruments are required.
The SPADI was translated and cross-culturally adapted according to current guidelines. Measurement properties of internal consistency, reproducibility, construct validity, ceiling and floor effects, and responsiveness of all instruments were tested in 100 patients with shoulder disorders. The patients filled out the questionnaires on 3 occasions: at baseline, 24 to 48 hours after baseline, and 4 weeks after baseline.
The instruments showed adequate internal consistency (Cronbach alpha between .78 and .93) and a good level of agreement, as reflected by low standard errors of measurement and minimal detectable change. The reliability (intraclass correlation coefficients) of the instruments varied from 0.82 to 0.96. Most instruments presented good levels of construct validity. All instruments showed acceptable levels of internal and external responsiveness.
The Portuguese Brazilian versions of the SPADI; the short form of the Disabilities of the Arm, Shoulder and Hand; a numeric pain rating scale; the Patient-Specific Functional Scale; and the Global Perceived Effect scale are reproducible, valid, and responsive instruments for assessing patients with shoulder disorders.
临床测量。
将肩痛和残疾指数（SPADI）跨文化适应为巴西葡萄牙语，并测试 SPADI 巴西葡萄牙语版本、上肢功能障碍、肩手残疾问卷简表、患者特定功能量表、数字疼痛评分量表和整体感知疗效量表在肩部疾病患者中的测量性能。
大多数肩部疾病的工具都是用英语开发的。为了在巴西使用，需要将这些工具翻译成巴西葡萄牙语、进行跨文化适应，并测试这些工具的测量性能。
根据当前指南翻译和跨文化适应 SPADI。在 100 名肩部疾病患者中测试所有工具的内部一致性、可重复性、结构有效性、天花板和地板效应以及反应性的测量性能。患者在基线、基线后 24 至 48 小时和基线后 4 周填写问卷 3 次。
这些工具显示出足够的内部一致性（Cronbach alpha 在.78 到.93 之间）和良好的一致性水平，反映在测量误差小和最小可检测变化低。工具的可靠性（组内相关系数）从 0.82 到 0.96 不等。大多数工具都表现出良好的结构有效性水平。所有工具都表现出可接受的内部和外部反应性水平。
SPADI 的葡萄牙语巴西版本；上肢功能障碍、肩手残疾问卷简表；数字疼痛评分量表；患者特定功能量表；以及整体感知疗效量表是一种可重复、有效且敏感的评估肩部疾病患者的工具。
