Abbreviations: CHJP, chronic hip joint pain; BMI, body mass index; UCLA, University of California Los Angeles Activity Score; ROM, range of motion; ER ROM90°, external rotation ROM with hip flexed to 90°; IR ROM90°, internal rotation ROM with hip flexed to 90°; ER ROM0°, external rotation ROM with hip in neutral flexion/extension 0°; IR ROM0°, internal rotation ROM with hip in neutral flexion/extension 0°; deg, degrees
Values are mean ± SD.
Independent sample t-tests were used.
UCLA: participants are asked to rate their activity level over the previous 6 months. 1=wholly inactive, dependent on others; 10= regularly participates in impact sports such as jogging, tennis, skiing, acrobatics, ballet, heavy labor, or backpacking.
Values are median (range)
Mann-Whitney U Test was performed. One control participant did not complete UCLA.
