CI = confidence interval; SDTM = standard deviations of the torque moments; Nm = Newton meter; BMI = body mass index; kg/m2 = kilogram per square meter; PASE = Physical Activity Scale for the Elderly; MS = mean sensitivity; dB = decibel; logMAR = logarithm of the minimum angle of resolution.
*Multivariable model was adjusted for age, gender, number of falls in the past 12 months and PASE score.
