A revealed the range of motion (joint angle) during 10 s balance on both static and moving platform condition. The ranges of motion were calculated as the maximum angle minus the minimum angle. B The angular velocity was calculated as the time-derivative of joint angle. The root mean squared angular velocity. Data are expressed as means ± SD. The data were analysed using independent t-tests for comparisons between CAI and HC groups. The “*” symbol indicates significant differences between the two groups (*p < 0.05). P-values and effect sizes (Cohen’s d) are shown.
