The comparison of foot clearance in novice and experienced independent walking using statistical parametric mapping

Abstract

Methodology As part of a longitudinal study of gait development, 20 infants participated in two test sessions at walking milestones. Firstly, within 3 weeks of taking five independent steps (age 416±54 days) then again when they could walk in a confident stable manner (78±25 days later). For both sessions infants were instrumented with markers defining the feet, lower limbs and pelvis. Infants were encouraged to walk in a nursery style laboratory environment while kinematic data was collected (Qualisys, Sweden; 100 Hz). Vertical foot (1st and 5th metatarsal heads and heel) marker trajectories were tracked during this time and trajectories during swing were exported from Visual 3D (C-motion, USA). Five swing phase trajectories and their variability (SD) were compared for novice v experienced walking utilising paired sample SPM1D t-tests in Python (Pataky, 2016).
