Objective To explore the independent influencing factors of kinesiophobia in patients after total knee arthroplasty and analyze the effect of rehabilitation training under the information-motivation-behavioral skills (IMB) model.
Methods A total of 385 patients undergoing primary unilateral total knee arthroplasty were selected, and the independent influencing factors of kinesiophobia in these patients after total knee arthroplasty were analyzed. Eighty-nine patients with kinesiophobia were divided into control group (n=44) and observation group (n=45) according to random number table method. The control group received routine rehabilitation intervention, while the observation group received rehabilitation intervention under the IMB model. The application effect of rehabilitation intervention under the IMB model in patients with kinesiophobia after total knee arthroplasty was analyzed.
Results Multivariate Logistic regression analysis showed that the analgesic effect, adverse reactions to anesthetics, preoperative anxiety level, preoperative depression level, postoperative self-efficacy, and postoperative family care level were all independent influencing factors of kinesiophobia in patients after total knee arthroplasty (P<0.05). Compared with before intervention, at 1 month and 3 months after intervention, the Tampa Scale of Kinesiophobia (TSK) scores and Numerical Rating Scale (NRS) scores of both groups decreased, while the Knee Society Score (KSS) and rehabilitation exercise compliance scores increased (P<0.05). Compared with the control group, at 1 month and 3 months after intervention, the TSK scores and NRS scores of the observation group were significantly lower, while the KSS and rehabilitation exercise compliance scores were significantly higher (P<0.05).
Conclusion There are multiple influencing factors for kinesiophobia in patients after total knee arthroplasty. Clinically, the implementation of rehabilitation training program under the IMB model is conducive to changing postoperative rehabilitation behaviors, improving kinesiophobia and pain levels after total knee arthroplasty, and enhancing knee function and rehabilitation training compliance.
