Effects of Walking Speed on the Balance Control and Movement Stability

Instrumented treadmill allowing collecting ground reaction force during a large number of successive cycles make possible for the method to analyze motor control errors defined as movement variability. Since dynamic stability is closely related to variability, the observed variability during dynamic tasks can thus offers insight into neuromuscular control mechanisms. In the current study, an instrumented treadmill were developed providing vertical ground reaction force and centre of pressure (COP). Being synchronized together with a motion capture system, a complete kinematic and dynamic stability analysis were performed on 10 young subjects during treadmill walking to provide quantified biomechanical data of gait performance. Gait variables, joint angles as well as motion of the centere of mass (COM) and pelvis were calculated. The differences between eight speed conditions were analyzed using one-way ANOVA (12333
