Area of Science:

Biomechanics
Orthopedic Engineering

Background:

Brace migration is a significant challenge that can compromise the therapeutic effectiveness of orthopedic devices.
Traditional evaluation methods, such as walking experiments, are often insufficient for precisely quantifying brace migration.
Understanding and predicting brace migration is crucial for improving treatment outcomes and device design.

Purpose of the Study:

To develop and validate an interaction model capable of predicting brace migration.
To investigate the influence of different mechanical mechanisms on the extent of brace migration.
To establish a more accurate method for evaluating therapeutic efficacy by addressing brace migration.

Main Methods:

Development of a novel interaction model incorporating instantaneous center of rotation (ICR) misalignment.
Validation of the predictive model through controlled walking experiments.
Comparative analysis of brace migration between four-linkage (FL) and spur gear (SG) mechanisms.

Main Results:

The developed interaction model demonstrated strong positive correlations in predicting migration for both four-linkage (r=0.952) and spur gear (r=0.898) mechanisms.
The model achieved low root mean squared errors (RMSE) of 0.53 mm for FL and 1.35 mm for SG.
The four-linkage mechanism exhibited significantly lower brace migration compared to the spur gear mechanism (p < 0.05).

Conclusions:

The interaction model provides an accurate prediction of brace migration.
The choice of mechanical mechanism significantly influences the degree of brace migration.
This predictive model offers a valuable tool for optimizing brace design and enhancing therapeutic efficacy.
