To explore the association between the exercise anticipation, function and self-efficacy in patients after knee surgeries over six months and to identify the predictors for rehabilitation.
This observational study used the cross-sectional survey method and was divided into two stages: (1) designing the experimental video materials and answer cards about exercise anticipation, and (2) analyzing the correlation of the level of exercise anticipation, knee function, modified gait efficacy scale (mGES), self-efficacy for rehabilitation outcome scale (SER), self-efficacy for exercise scale (SEE), time up and go task (TUG) and knee joint angle in walking. We used IBM SPSS modeler 18.0 software for establishing the Bayesian network data mining model, which can identify strong positive and negative associations.
A total of 110 patients were included in this study. Our research confirmed that the exercise anticipation score exhibited the significant correlation with SER (=0.552, <0.01), SEE (=0.457, <0.01), TUG (=-0.419, <0.01) and knee joint angle in walking (=-0.342, <0.01). There is only one parent node of exercise expectation, that is, rehabilitation self-efficacy, which shows that the rehabilitation self-efficacy of patients after knee surgery is directly related to their ability to judge exercise expectation. Meanwhile this study verified the model results, and the area under the ROC curve (AUC) is 0.572 (755/1320), indicating that the prediction performance is acceptable.
This preliminary study confirmed that improving the exercise anticipation and rehabilitation self-efficacy is an important method of enhancing the knee function in patients after knee surgeries over six months. In the future, the long-term effect of the exercise anticipation and self-efficacy should be researched.
探讨膝关节手术后6个月以上患者的运动预期、功能和自我效能之间的关联，并确定康复的预测因素。
本观察性研究采用横断面调查方法，分为两个阶段：（1）设计关于运动预期的实验视频材料和答题卡片；（2）分析运动预期水平、膝关节功能、改良步态效能量表（mGES）、康复结果自我效能量表（SER）、运动自我效能量表（SEE）、定时起立行走测试（TUG）以及步行时膝关节角度之间的相关性。我们使用IBM SPSS modeler 18.0软件建立贝叶斯网络数据挖掘模型，该模型可识别强正相关和负相关。
本研究共纳入110例患者。我们的研究证实，运动预期得分与SER（=0.552，<0.01）、SEE（=0.457，<0.01）、TUG（=-0.419，<0.01）以及步行时膝关节角度（=-0.342，<0.01）显著相关。运动预期只有一个父节点，即康复自我效能，这表明膝关节手术后患者的康复自我效能与他们判断运动预期的能力直接相关。同时本研究验证了模型结果，ROC曲线下面积（AUC）为0.572（755/1320），表明预测性能可接受。
这项初步研究证实，提高运动预期和康复自我效能是增强膝关节手术后6个月以上患者膝关节功能的重要方法。未来，应研究运动预期和自我效能的长期效果。
