*The 1st test was conducted at the beginning of this research (192 patients), the 2nd test was conducted 1 week later to calculate the test-retest reliability (ICC) of the HAGOS-C (192 patients), and the 3rd test was conducted 6 months later to calculate the responsiveness (ES, SRM) of the HAGOS-C (158 patients)
