  1. Statistical analyses of the control and valgus groups were performed using Welch’s t-test. Age is presented as the mean (range). RFA, NNHT, BMI, ankle activity score, and muscle strength are presented as means ± standard deviation and 95% confidence intervals
  2. RFA, rearfoot angle; NNHT, normalized navicular height truncated; BMI, body mass index
