Mechanically induced stumbling during human treadmill walking

Abstract: A new method to study the reactions to unexpected mechanical perturbations during human walking on a treadmill is presented.Perturbations consisted of an obstruction of the forward swinging foot during the early swing phase. These were caused by obstacles which were dropped on the treadmill in front of the subject The timing o f the perturbation was controlled by an electromagnet which released the obstacle at a preprogrammed delay after left or right heel strike. This kind of perturbation evoked stumbling rea… Show more

“…The strategies observed on a treadmill were similar to those found on the ground, as has been reported by several authors (Schillings et al 1996;Owings et al 2001;Forner Cordero et al 2003). Despite their mechanical differences, the human balance control mechanisms remained basically the same.…”

“…Experimental work over the last two decades has shown three main groups of recovery strategies to a stumble, either on the floor (Eng et al 1994) or on a treadmill (Dietz et al 1986(Dietz et al , 1987Schillings et al 1996;Forner Cordero et al 2003): elevating, lowering, and delayed lowering. The elevating strategy, which tries to proceed with the perturbed step, was executed as a response to a perturbation during early swing.…”

“…Because the main features of motoneuron activation during these functionally important reflexes seem similar in fictive and real locomotion (Quevedo et al 2005), these results also provide a framework for understanding the synaptic events in motoneurons that result in lifting the foot over an obstacle to avoid tripping in intact preparations. Similarities between the stumbling reaction described here and in humans (Lam et al 2003;Schillings et al 1996;Zehr et al1997) include the increase in ongoing flexor activity, and when using an electrical stimulus train in adults, inhibitory effects in TA as well as a facilitation of ankle extensor EMG (Zehr et al 1997).…”

“…In de proeven die in Nijmegen werden uitgevoerd wordt echt gestruikeld doordat de proefpersonen een plankje dat op de loopband wordt geplaatst, niet kunnen zien aankomen (bijvoorbeeld doordat het zicht op het plankje is afgeschermd, zie Schillings et al 1996;. Struikelingen worden uitgelokt met de meetopstelling zoals getoond in de figuur.…”
