Analysis of influencing factors and construction of nomogram prediction model of postoperative kinesiophobia in patients undergoing total knee arthroplasty
Abstract
Objective: To explore the influencing factors of kinesiophobia and to establish a nomogram prediction model.
Methods: A retrospective observational study was conducted in 354 patients who underwent TKA in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from December 2019 to December 2022. Sociodemographic characteristics, anesthesia methods, Tampa Scale for Kinesiophobia (TSK), numeric rating scale (NRS), hospital for special surgery (HSS), activities of daily living (ADL), and self-rating anxiety scale (SAS) were reviewed and analyzed. Logistic regression analysis was used to identify the influencing factors of kinesiophobia, and a nomogram model was established based on the identified influencing factors and verified by consistency index (C-index), calibration curve, and receiver operating characteristic (ROC) curve.
Results: Incidence of kinesiophobia in patients who received TEAS combined with western medicine (dexmedetomidine and remifentanil) was significantly lower than that in patients who received western medicine alone. The logistic regression analysis showed that family monthly income level, HSS, ADL, and combined TEAS and western medicine approach were independent protective factors for kinesiophobia (all P<0.05). The degree of pain and anxiety were independent risk factors for kinesiophobia (both P<0.05). A nomogram model was constructed with C-index of 0.721 (0.658, 0.784), and the area under curve (AUC) was 0.748 (95 %CI: 0.685-0.807). The calibration curve also showed good consistency between actual observations and nomogram model predictions.
Conclusions: Family monthly income level, anesthesia methods, NRS, HSS, ADL, and SAS scores are influencing factors of kinesiophobia, and the nomogram model can be useful for predicting postoperative kinesiophobia.
