: The "Exercise-Induced Leg Pain" questionnaire was developed (in German) for the evaluation of the severity of symptoms and sports ability in individuals with exercise-induced leg pain. The purpose of the present study was to translate and cross-culturally adapt this questionnaire into French and to study the reliability and validity of this French-language version.: The translation and cross-cultural adaptation of the original "Exercise-Induced Leg Pain" was performed according to established guidelines. The translation part was carried out in six stages: (i) two initial translations from German to French; (ii) synthesis of the two translations; (iii) backward translations; (iv) comparison between the backward translations and the original questionnaire by an expert committee; (v) pretest; and (vi) approval of the final version of the French-language "Exercise-Induced Leg Pain" questionnaire. To validate this questionnaire, 84 subjects were recruited (28 pathological patients with a confirmed diagnosis of chronic leg pain, 28 asymptomatic sport students, and 28 healthy control athletes). The discriminative power of the questionnaire was tested, as well as its reliability (internal consistency and test-retest reliability after a 7-10-day interval), construct validity and floor/ceiling effects. The French version of the "Exercise-Induced Leg Pain" questionnaire was generated without any major difficulties. The ability of the questionnaire to discriminate between the three groups of subjects was demonstrated with a total score of 61.0 ± 18.5 for the pathologic group; 93.9 ± 7.57 for the asymptomatic group and 94.1 ± 9.79 for the control group. A high internal consistency (Cronbach's alpha of 0.93) and an excellent test-retest reliability [intraclass coefficient correlation: 0.98 (95% confidence interval: 0.97-0.99, < 0.001)] indicated that the "Exercise-Induced Leg Pain" is reliable. The questionnaire also demonstrated good construct validity against different subscales of the Short Form-36 questionnaire, a generic quality of life questionnaire, with more than 87% of the prespecified hypotheses confirmed. Finally, no floor effects or ceiling effects were observed. The French version of the « Exercise-Induced Leg Pain » was successfully translated and cross-culturally adapted. The questionnaire is consistent, valid and reliable for evaluating French-speaking patients with chronic exercise-induced leg pain.Implications for rehabilitationThe "Exercise-Induced Leg Pain" questionnaire aims to assess the severity of symptoms that impact the function and sports ability of patients with exercise-induced leg pain;The French version of the « Exercise-Induced Leg Pain » was successfully translated and cross-culturally adapted. The questionnaire is consistent, valid and reliable for evaluating French-speaking patients with chronic exercise-induced leg pain.
: “运动引起的腿部疼痛”问卷是为评估运动引起的腿部疼痛患者的症状严重程度和运动能力而开发的（德语版）。本研究的目的是将该问卷翻译成法语，并研究其法语版本的信度和效度。: 该问卷的德译法翻译和文化调适遵循既定指南进行。翻译部分分六个阶段进行：（i）从德语到法语的两次初始翻译；（ii）两次翻译的综合；（iii）回译；（iv）由专家委员会对回译与原始问卷进行比较；（v）预测试；以及（vi）最终确定法语版“运动引起的腿部疼痛”问卷。为验证该问卷，共招募了 84 名受试者（28 名慢性腿部疼痛确诊患者、28 名无症状运动学生和 28 名健康对照组运动员）。测试了问卷的辨别力，以及信度（内部一致性和 7-10 天间隔后的重测信度）、结构效度和下限/上限效应。法语版“运动引起的腿部疼痛”问卷的生成没有遇到任何重大困难。问卷能够区分三组受试者，总分分别为病理性组 61.0±18.5；无症状组 93.9±7.57；对照组 94.1±9.79。高内部一致性（Cronbach's alpha 为 0.93）和极好的重测信度[组内相关系数相关性：0.98（95%置信区间：0.97-0.99， < 0.001)]表明“运动引起的腿部疼痛”是可靠的。该问卷与短格式 36 问卷（一种通用生活质量问卷）的不同子量表也具有良好的结构效度，超过 87%的预设假设得到验证。最后，没有发现下限或上限效应。法语版的“运动引起的腿部疼痛”问卷成功地被翻译和跨文化调适。问卷对于评估讲法语的慢性运动引起的腿部疼痛患者是一致、有效且可靠的。对康复的启示该“运动引起的腿部疼痛”问卷旨在评估影响运动引起的腿部疼痛患者功能和运动能力的症状严重程度；法语版的“运动引起的腿部疼痛”问卷成功地被翻译和跨文化调适。问卷对于评估讲法语的慢性运动引起的腿部疼痛患者是一致、有效且可靠的。
