In this paper, we question how these finding build upon the original work by Sherrington, who proposed that the flexor reflex is the basic building block of flexion during swing phase. One of the basic modules involves the flexion of the leg during swing and it was shown that this module is already present in neonates ( Dominici et al., 2011). Recently there has been a growing interest in the modular organization of leg movements, in particular those related to locomotion. 3Department of Mechanical Engineering, KU Leuven, Heverlee, Belgium.2Department of Research, Sint Maartenskliniek, Nijmegen, Netherlands.1Department of Kinesiology, KU Leuven, Heverlee, Belgium.
