Abstract

[Purpose] To examine the effects of a perceptual stimulus insole (PSI) to provide positional information at initial contact on foot dynamics during gait. [Subjects and Methods] The lower limbs of 15 healthy adults without a history of orthopedic disorders were examined. The participants walked under 4 different conditions to compare the dorsiflexion angle at initial and the height of the toes during the swing phase: a spherical seal as a simulated PSI was attached to the inner (Condition-1), outer (-2), or rear (-3) part of the back of the heel, or it was not attached (-4). [Results] The dorsiflexion angle was greater, and the position of the toes was higher under Conditions-2 and -3 compared with -4. [Conclusion] Active gait control according to the position of the PSI was observed, indicating that users planned and executed movements suitable for the task while distinguishing plantar sensations. The results support the applicability of this method as a new training approach for dynamic postural control.
