Cross-cultural adaptation and validation of the simplified Chinese version of the Exercise-Induced Leg Pain Questionnaire (EILP).

This study translated and cross-culturally adapted Exercise-Induced Leg Pain Questionnaire into a Simplified Chinese version, and evaluated its reliability and validity in individuals with exercise-induced leg pain.Moderate to substantial correlations between the Simplified Chinese version of the Exercise-Induced Leg Pain Questionnaire and VAS, UCLA, as well as physical subscales of SF-36 were observed.Exploratory factor analysis revealed that the 3-factor loading explained 74.736% of the total variance [Kaiser­Mayer­Olkin (KMO) = 0.672, C² = 665.34, p < 0.001].Simplified Chinese version of the Exercise-Induced Leg Pain Questionnaire was demonstrated to have acceptable simplicity, good reliability, and validity in individuals with exercise-induced leg pain, which could be recommended for patients in Chinese mainland.
