Kinetic data analysis evidenced decreased knee maximum extensor moment during early stance KMmax (from 0.38 to 0.12; t(7) = 3.1, p <.05) and increased maximum flexor moment in late stance KMmin (from -0.3 to -0.5; t(7) = 3.3, p <.05). The hip power generation in pre-swing phase HP3 (from 1.5 to 1.1; t(7) = 3.3, p <.05) decreased as well.
