Overview

Cross-sectional study observes distinct foot pressure links to knee kinematics across classification methods in pronated feet, indicating navicular drop better captures dynamic movement.

Key Points

  • To investigate the association between foot pressure distribution and lower-extremity kinematic variables during a single-leg squat in individuals with and without pronated feet using two different classification methods.
  • Assessed 30 participants performing single-leg squats on their dominant leg, classifying foot posture as pronated or normal using the Foot Posture Index (FPI ≥ +6) and navicular drop test (ND ≥ 10 mm).
  • Recorded foot pressure distribution across four forefoot regions with a pressure platform and measured two-dimensional kinematic variables using Pearson correlation coefficients.
  • In the ND-classified pronated group, hallux pressure correlated positively with knee-inward distance (r = 0.529, p = 0.024) and tibia tilt angle (r = 0.513, p = 0.029), whereas no significant correlations occurred in the FPI pronated group.
  • In normal-foot groups, central forefoot pressure demonstrated a significant positive correlation with dynamic knee valgus angle under both FPI- and ND-based classifications.
