Summary
This study assessed the reliability of the modified Oxford foot model for shod walking and running. Results show good between-day and within-session reliability, supporting its use in clinical gait analysis.
Area of Science:
- Biomechanics
- Gait Analysis
- Orthopedics
Background:
- Measuring foot kinematics during gait is crucial.
- The Oxford foot model is widely used for walking and running analysis.
- Previous reliability studies primarily focused on barefoot conditions.
Purpose of the Study:
- To determine the between-day and within-session reliability of the modified Oxford foot model.
- To calculate the minimum detectable difference for key kinematic variables.
- To evaluate the model's utility during shod walking and running.
Main Methods:
- Three-dimensional gait analysis was performed on healthy adult male runners.
- Participants completed five trials each of walking and running.
- Data were collected on two separate days (at least 5 days apart) to assess reliability.
Main Results:
- Within-session reliability was generally higher than between-day reliability.
- Relative kinematic variables demonstrated greater reliability than absolute variables.
- Between-day reliability for shod conditions was comparable to previously reported barefoot data.
Conclusions:
- The modified Oxford foot model exhibits good reliability for both shod walking and running.
- These findings extend the application of the Oxford foot model to include footwear.
- The established reliability data will help interpret meaningful changes in shod gait studies.
