Background: Evaluating responsiveness and calculating minimally important change (MIC) for the Persian-versionof the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire following physiotherapy in patients with lateralelbow tendinopathy (LET).Methods: 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 changescale (GRoC). The receiver operating characteristic (ROC) curve and correlation analysis were used for evaluating theresponsiveness. The MIC was determined by determining a desirable cutoff on the ROC curve.Results: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 subscalerevealed 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 pointsfor total PRTEE, pain subscale, and function subscale, respectively.Conclusion: The Persian-version of the PRTEE questionnaire has acceptable responsiveness and can measurechanges in patients with LET following physiotherapy. We advocate using the PRTEE questionnaire in both clinicalsettings and research.Level of evidence: IV
