Abstract

Brace migration undermines therapeutic efficacy, which is traditionally evaluated through walking experiments. This study developed an interaction model that considered the instantaneous center of rotation (ICR) misalignment to predict migration. The model was validated by walking experiment. Results show a strong positive correlation for four-linkage (FL) (r = 0.952, p < 0.01, root mean squared error (RMSE) = 0.53 mm) and spur gear (SG) (r = 0.898, p < 0.01, RMSE = 1.35 mm) mechanisms. The FL exhibits lower migration than SG (p < 0.05). In conclusion, the interaction model accurately predicts migration, emphasizing the influence of mechanism on migration.

预测支架迁移的互动模型，并通过行走实验进行验证。

支具移位会影响疗效，而传统的疗效评估是通过行走实验进行的。本研究建立了一个交互模型，该模型考虑了瞬时旋转中心（ICR）错位来预测移位。该模型通过行走实验进行了验证。结果表明，四连杆（FL）具有很强的正相关性（r = 0.952, p r = 0.898, p p
