Table 1: The characteristics of participants at baseline (Mean(SD)).
WBV: whole body vibration group; CON: control group; CSA: cross-sectional area; VM; vastus medialis; TUG: Timed up-and-go test; 5STS: Fiverepetition sit-to-stand test; 10MWT: 10-meter walking test. The p values were for between group comparisons.
