  1. Note: WHOQOL-BREF: A higher score indicates better health-related quality of life. SIPP-RS: A higher score indicates more self-reported impairments. IBM-FRS: A higher score indicates better functional status. 6MWD: A higher score indicates a longer distance in 6 min. MFM: A higher score indicates better motor function
