Study Design Clinical measurement study. Background Ankle sprain is a common condition. Therefore, translated, culturally adapted, and clinimetrically tested instruments for measuring the ankle are needed. Objectives To translate and cross-culturally adapt the Sports Athlete Foot and Ankle Score (SAFAS) and the global rating of change (GROC) into Brazilian Portuguese. This study also aimed to test the measurement properties of the SAFAS, the GROC, and the existing Brazilian-Portuguese versions of the numeric pain-rating scale (NPRS) and the ankle-hindfoot scale of the American Orthopaedic Foot and Ankle Society (AOFAS) in a group with ankle sprain. Methods The SAFAS and GROC instruments were cross-culturally adapted into Brazilian Portuguese and pretested in this population (n = 18). The measurement properties of the SAFAS, GROC, NPRS, and AOFAS (internal consistency, ceiling and floor effects, construct validity, reproducibility, and responsiveness) were tested in a test-retest design in patients with ankle sprain at baseline (n = 63) and at follow-up periods of 48 to 72 hours (n = 53) and 4 weeks (n = 43) after baseline. Results The SAFAS, GROC, NPRS, and AOFAS yielded considerable internal consistency (Cronbach alpha ranging from .76 to .97), moderate reliability (intraclass correlation coefficient model 2,1 ranging from 0.59 to 0.80), and dubious agreement (percentage of the standard error of measurement ranging from 13% to 22.43%). The highest correlations on construct validity were observed among the 4 SAFAS subscales (Pearson r = 0.75 to 0.86, P<.01), but statistically significant values appeared in the intercorrelation of instruments. There were no observed floor or ceiling effects in any of the instruments. All of their scores of change showed moderate correlation with the GROC (r = -0.48 to 0.30, P<.05) and could be classified as responsive. Conclusion The Brazilian-Portuguese versions of the SAFAS, GROC, NPRS, and AOFAS had acceptable measurement properties in high-performing athletes. J Orthop Sports Phys Ther 2016;46(12):1042-1050.

临床测量研究。背景：踝关节扭伤是一种常见病症。因此，需要经过翻译、文化调适和计量测试的踝关节测量工具。目的：将 Sports Athlete Foot and Ankle Score（SAFAS）和整体变化评级（GROC）翻译成巴西葡萄牙语，并检验其在踝关节扭伤患者中的测量性能。本研究还旨在检验巴西葡萄牙语版数字疼痛评分量表（NPRS）和美国矫形足踝协会踝关节-后足量表（AOFAS）的测量性能。方法：对 SAFAS 和 GROC 进行文化调适并预测试（n = 18）。采用测试-再测试设计，在基线时（n = 63）和基线后 48 至 72 小时（n = 53）和 4 周（n = 43）时，对 SAFAS、GROC、NPRS 和 AOFAS 的测量性能（内部一致性、天花板和地板效应、结构有效性、可重复性和反应性）进行了测试。结果：SAFAS、GROC、NPRS 和 AOFAS 具有较高的内部一致性（Cronbach α 值范围为.76 至.97），中等可靠性（模型 2，1 的组内相关系数范围为 0.59 至 0.80）和可疑的一致性（测量误差的标准百分比范围为 13%至 22.43%）。在结构有效性方面，SAFAS 的 4 个分量表之间的相关性最高（Pearson r = 0.75 至 0.86，P<.01），但在各仪器的相互关联中，观察到统计学上显著的值。在任何仪器中均未观察到地板或天花板效应。各仪器的变化评分与 GROC 均呈中度相关（r = -0.48 至 0.30，P<.05），且可归类为有反应性。结论：SAFAS、GROC、NPRS 和 AOFAS 的巴西葡萄牙语版本在高表现运动员中具有可接受的测量性能。J Orthop Sports Phys Ther 2016;46(12):1042-1050。2016 年 11 月 8 日在线发表。doi：10.2519/jospt.2016.6218.
