Bilateral Gait Asymmetry Exists Despite Similar Foot Morphology in Runners

Designers should acknowledge that even individuals with anatomically similar left and right feet can exhibit distinct biomechanical patterns during movement.

Physical Activity and Health · 2023

01

Key Findings

  • 01No significant differences were found in foot morphological characteristics (dimensions, hallux valgus angle, navicular drop) between the left and right feet.
  • 02Significant differences were observed in running kinematics between the left and right limbs, including peak foot eversion, peak knee flexion, and peak hip adduction.

Application

Design takeaway

When designing products or systems that interact with the human body during dynamic activities, assume asymmetry unless proven otherwise, and consider individual limb performance.

How to apply

When developing custom-fit athletic gear, use motion capture or detailed gait analysis for each limb to inform design adjustments.

Project actions

  • 01When researching user movement, consider analyzing both left and right sides of the body separately.
  • 02If your design interacts with a user's limbs, think about how asymmetry might affect its function.

Method & Evidence

AimTo investigate if there are differences in foot morphology and running gait patterns between the left and right limbs of recreational runners.
MethodObservational study with quantitative analysis
ProcedureResearchers measured foot dimensions and angles (hallux valgus, navicular drop) for both feet of participants. They then analyzed bilateral running kinematics using 2D video analysis to capture movements of the foot, knee, and hip.

Strengths & Limitations

Strengths

  • +Investigated both morphology and kinematics.
  • +Analyzed both left and right limbs for each participant.

Limitations

The study was conducted on recreational runners, so findings might differ for professional athletes or individuals with specific injuries. The 2D analysis is a simplification of complex 3D motion.

Reliability & validity

The use of standardized measurements for morphology and established video analysis techniques for kinematics contributes to the study's reliability. The focus on asymptomatic runners enhances the validity of findings related to typical gait patterns.

Think critically

If morphology is similar but gait is different, what other factors (neuromuscular control, previous injuries, habit) might be influencing this asymmetry?

05

Design Principles

"Design for individual variability, even within a single user's bilateral symmetry."

This finding is crucial for designing adaptive or personalized equipment, such as footwear, orthotics, or even athletic training programs. Ignoring potential between-limb differences could lead to suboptimal performance or increased injury risk.

06

What This Means for Your Design

Even if your left and right feet look the same, how you run on them might be different. Designers need to remember this when making things like shoes.

Paragraph starter

Research indicates that significant differences in running kinematics can exist between a runner's left and right limbs, even when their foot morphology is similar. This highlights the importance of considering bilateral asymmetry in the design of athletic equipment and training protocols, as a one-size-fits-all approach based on perceived symmetry may not be optimal.
