Background: Ankle-foot orthoses (AFOs) are often prescribed for people with stroke to address motor impairment. However, not all patients adhere to using their AFOs as prescribed. Predictors of AFO adherence are likely to constitute useful targets for interventions that aim to promote this behavior.

Objective: To identify the predictors of AFO adherence in people with stroke using an established theoretical framework, namely the Theory of Planned Behavior (TPB; Ajzen, 1991).

Study design: Prospective survey design.

Method: N = 49 people who had been prescribed an AFO after a stroke completed a TPB questionnaire. One month later, they completed another questionnaire that measured adherence to AFOs as prescribed by an orthotic practitioner. Predictors of intention and AFO-adherence behavior were identified using regression analyses.

Results: Adherence to AFOs was 63%. The TPB accounted for 61% of the variance in intentions and 43% of the variance in AFO-adherence behavior. Attitude and perceived behavioral control were predictors of intention, and intention was the sole predictor of behavior.

Conclusion: The TPB is a useful model for explaining adherence to AFOs in people with stroke. Interventions could be designed to increase intentions to use an AFO as prescribed by promoting positive attitudes towards, and perceived behavioral control of AFO adherence.

背景： 踝足矫形器（AFOs）常被开给中风患者以解决运动功能障碍。然而，并非所有患者都会按照处方使用他们的AFOs。预测AFO依从性的因素可能会构成有助于促进这种行为的干预措施的目标。

目的： 利用已确立的理论框架，即计划行为理论（TPB；Ajzen, 1991），来识别中风患者使用AFOs时依从性预测因素。

研究设计： 前瞻性调查设计。

方法： 49名在中风后被开具了AFO的患者完成了TPB问卷。一个月后，他们完成了一份测量依从性情况的问卷，该问卷评估的是他们在矫形师指导下使用AFO的情况。通过回归分析确定意图和AFO依从行为的预测因素。

结果： AFOs依从率为63%。TPB解释了意图变异性的61%，以及AFO依从性行为43%的变异。态度和感知的行为控制是意向的预测因子，而意图则是行为的唯一预测因子。

结论： 计划行为理论是一个有用的模型，用于解释中风患者使用AFOs时的依从情况。可以通过促进对AFO依从性的积极态度和感知的行为控制来增加处方使用AFO的意图，并设计干预措施以实现这一目标。
