^* Mean comparison from baseline;

^# SPPB score range 0–12, higher score indicates better mobility;

^& faster speed indicates better mobility;

^$ faster time indicates better mobility;

^± FES-1 score range 7–28, low score indicates no concern, maximum score of 28 indicates severe concern about falling;

^€AQOL-4D score range 12–48, lower score indicates better HRQoL.
