Reducing the foot trajectory variabilities during walking through vibratory stimulation of the plantar surface of the foot

Abstract Variabilities or fluctuations in foot clearance are considered as a risk factor for falls during walking in older adults. The present study aimed to investigate whether the foot trajectory variability can be reduced by applying vibratory stimulation to the foot's plantar surface during...
