Exploration of Metrics for Leg Length Discrepancy Using a Wearable Gait Analysis System
Abstract:
The purpose of this study was to explore effective metrics for differentiating levels ofleg length discrepancy (LLD) using a wearable device.
Design:
A wearable device for measuring ground reaction forces and kinetic features was developed in this study.
Participants:
Eight volunteers without previously diagnosed LLD walked along a 120.0 m walkway with a 2.5 cm and 3 cm foot spacer to simulate LLD.
Main Outcome Measures:
The p-values of thirteen kinetic and kinematic metrics between normal and LLD walking.
Results:
Difference in stance time duration, difference in heel reposition time, and ratio difference of loading effect showed statistical difference between normal walking and simulated LLD walking.
Conclusion:
The metrics with statistical difference may serve as effective indicators oflow levels ofLLD and be implemented into a point-of-care system for gait analysis.

Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
