SD = Standard Deviation; FPPA=frontal plane projection angle; N=newtons; VAS= visual analog scale

^*P-value: change during intervention phase compared to change during control phase (statistically significant at 0.05 alpha level)

^†values reported as % of leg length

^#Prior to analysis, data were log transformed to follow the multivariate normal distribution.
