Summary
The Oxford Foot Model (OFM) demonstrates high reproducibility for assessing foot and ankle range of motion in healthy adults during functional tests like the Anterior and Lateral Step Down Tests.
Area of Science:
- Biomechanics
- Orthopedics
- Kinesiology
Background:
- Accurate assessment of foot and ankle biomechanics is crucial in clinical practice.
- The Oxford Foot Model (OFM) is a tool used for analyzing foot motion.
- Reproducibility of measurement tools is essential for reliable clinical data.
Purpose of the Study:
- To analyze the reproducibility of the Oxford Foot Model (OFM).
- To evaluate OFM performance in healthy adults during the Anterior Step Down Test (SDA) and Lateral Step Down Test (SDL).
Main Methods:
- Five healthy participants (10 limbs) were assessed across four sessions over two weeks.
- Two independent examiners conducted sessions to assess inter-examiner reliability.
- Intra-day and inter-session repeatability were measured using the Standard Error of Measurement (SEM).
Main Results:
- The Oxford Foot Model (OFM) showed high repeatability for both SDA and SDL tests.
- Intra-examiner SEM ranged from 0.44° to 2.43°.
- Inter-examiner SEM ranged from 0.55° to 2.01°.
Conclusions:
- The Oxford Foot Model (OFM) is a reproducible method for assessing the range of motion in healthy adults.
- OFM can be reliably used during functional tests such as the SDA and SDL.
