Baseline characteristics
pain, KOA
All dependent variables were normally distributed, as confirmed by the Shapiro–Wilk tests (p > 0.05). Chi–square tests showed no significant differences in sex (p = 0.816), unilateral or bilateral KOA (p = 0.901), Kellgren/Lawrence radiographic grade (p = 0.824), and side of the more affected leg (p = 0.842) between the two groups. Independent t-tests showed no significant differences in age (p = 0.323), height (p = 0.129), body mass (p = 0.451), body mass index (p = 0.928), leg length (p = 0.145) and pain score of more (p = 0.761) and less (p = 0.759) affected legs between the two groups (
