Summary
This study presents a reliable clinical method for measuring foot and ankle kinematics during walking. The developed technique accurately assesses normal foot motion, aiding in the comparison of pathological foot conditions.
Area of Science:
- Biomechanics
- Orthopedics
- Clinical Measurement
Background:
- Accurate kinematic measurement of foot function is crucial for diagnosing and managing various foot deformities.
- Existing methods may lack the precision or clinical applicability needed for comprehensive foot assessment.
Purpose of the Study:
- To develop and validate a novel kinematic measurement method for the foot and ankle.
- To establish a reliable clinical tool for assessing foot function in both healthy and pathological conditions.
- To provide a reference for normal foot motion patterns.
Main Methods:
- Modeling the ankle as two hinge joints using anatomical axes derived from projection angles.
- Defining descriptive angles between anatomical landmarks for the midfoot and forefoot.
- Utilizing 17 markers on the lower leg and foot, tracked during walking gait in 10 healthy adults.
Main Results:
- Established a reliable method for reproducible kinematic measurements of the foot and ankle.
- Determined normal foot motion patterns during walking.
- Developed functional angles for improved clinical application of kinematic data.
Conclusions:
- The developed kinematic measurement method is reliable and clinically viable.
- The method provides a robust basis for assessing foot function and comparing pathological deviations.
- This technique enhances the clinical application of foot kinematic data.
