Determination of the step duration of gait initiation using a mechanical energy analysis

Timing Variability during Gait Initiation Is Increased in People with Alzheimer’s Disease Compared to Controls

“…An examination of mechanical energy production during gait initiation may help to explain why second and In an energy analysis of gait initiation steady-state walking was reported to be established after three steps [38] . The first step propels the body into a dynamic state.…”

“…Gait initiation was defined as the first three steps commencing from a standing start based on the number of steps necessary to reach steady-state walking [38] . The spatiotemporal variables analyzed included stride length, step width, stride time and double support time during gait initiation for each walk.…”

Reinforcement Learning of Stable Trajectory for Quasi-Passive Dynamic Walking of an Unstable Biped Robot

“…This two-stages learning reminds us of a developmental progression found at least in humans [Bernstein (1968); Newell & Vaillancourt (2001)] which increases the degree of freedoms as the learning proceeds; after a primitive control is achieved for a restricted system with a low dimensionality, frozen dimensionality is gradually released to realize more complex and smooth movements by the high-dimensional system. Furthermore, animals seem to employ different controllers in the initiation phase and in the maintenance phase for effect e.g., it has been known that three steps in average are required to initiate stationary walking in humans [Miller & Verstraete (1996)]. We consider the first stage of our approach could correspond to the initiation stage above.…”

The impact of different footwear characteristics, of a ballet flat pump, on centre of pressure progression and perceived comfort

“…The experimental set-up for cantilever bending tests (left) and a typical bending moment/angle curve (right). speed prior to data capture and prevent stepping onto the Plate [28]. The data collected were processed using computer programme written specifically for this study using Matlab (r2013a, Mathworks Inc., USA) to calculate the progression angle, contact time and velocity of the centre of pressure at the following times in gait [24]:…”
