Area of Science:

  • Biomechanics
  • Human Locomotion
  • Gait Analysis

Background:

  • Dynamic stability is crucial for human locomotion.
  • Objective measurement of dynamic stability is needed for performance evaluation across diverse environments.
  • Plantar pressure data offers a potential source for dynamic stability metrics.

Purpose of the Study:

  • To investigate the suitability of parameters from plantar pressure measurements for a dynamic stability model.
  • To identify reliable plantar pressure-derived metrics that reflect changes in gait stability.

Main Methods:

  • Collected in-shoe plantar pressure data using FScan system from 15 subjects.
  • Subjects performed four walking tasks of increasing instability.
  • Analyzed six specific parameters for reliability, sensitivity to instability, and relation to existing literature.

Lower-Limb Biomechanical Characteristics Associated with Unplanned Gait Termination Under Different Walking Speeds

Published on: August 25, 2020

Main Results:

  • Six parameters reliably calculated from plantar pressure data were identified.
  • These parameters demonstrated an increase with task-induced instability.
  • Identified parameters included CoF position (A/P and M/L), double support time, stance time, cell triggering frequency, and max lateral CoF position.

Conclusions:

  • Plantar pressure parameters are suitable inputs for dynamic gait stability models.
  • A combination of these parameters can form a reliable index of dynamic gait stability.
  • This approach enhances objective assessment of human locomotor performance.
