Evaluating responsiveness and calculating minimally important change (MIC) for the Persian-version of the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire following physiotherapy in patients with lateral elbow tendinopathy (LET).
We enrolled 82 patients with LET to complete the PRTEE. After completing four weeks of physiotherapy, all patients were reevaluated by the PRTEE. The patients also rated their changes on a 7-point global rating of change scale (GRoC). The receiver operating characteristic (ROC) curve and correlation analysis were used for evaluating the responsiveness. The MIC was determined by determining a desirable cutoff on the ROC curve.
The results showed a moderate relationship (Spearman's correlation coefficient= 0.43-0.56) of total PRTEE, pain subscale, and function subscale with the GRoC scale. The total PRTEE, pain subscale, and function subscale revealed an area under the curve of 0.87, 0.82, and 0.83, respectively. We found the MICs 31.33, 14.5, and 15.5 points for total PRTEE, pain subscale, and function subscale, respectively.
The Persian-version of the PRTEE questionnaire has acceptable responsiveness and can measure changes in patients with LET following physiotherapy. We advocate using the PRTEE questionnaire in both clinical settings and research.
评估外侧肘肌腱病（LET）患者物理治疗后波斯语版患者自评网球肘评估（PRTEE）问卷的反应性并计算最小重要变化（MIC）。
我们纳入了82例LET患者以完成PRTEE评估。在完成四周的物理治疗后，所有患者均通过PRTEE进行重新评估。患者还根据7分整体变化评定量表（GRoC）对自身变化进行评分。采用受试者工作特征（ROC）曲线和相关性分析来评估反应性。通过确定ROC曲线上的理想截断点来确定MIC。
结果显示PRTEE总分、疼痛子量表和功能子量表与GRoC量表之间存在中等程度的相关性（Spearman相关系数 = 0.43 - 0.56）。PRTEE总分、疼痛子量表和功能子量表的曲线下面积分别为0.87、0.82和0.83。我们分别发现PRTEE总分、疼痛子量表和功能子量表的MIC为31.33分、14.5分和15.5分。
PRTEE问卷的波斯语版具有可接受的反应性，能够测量LET患者物理治疗后的变化。我们提倡在临床环境和研究中使用PRTEE问卷。
