Abstract: Objective To explore the effect of Cox interaction model of client health behavior on kinesiophobia patients with osteoporotic vertebral compression fracture after minimally invasive procedures.Methods 96 patients with kinesiophobia after percutaneous vertebroplasty and percutaneous kyphoplasty in our hospital from October 2020 to March 2021 were selected as observation group,among whom 50 patients admitted to hospital from October 2020 to December 2020 served in an observation group,and 46 patients admitted to the hospital from January 2021 to March 2021 were selected into a control group.The observation group was implemented with Cox interaction model of client health behavior,and the control group was implemented with the conventional nursing.The differences of two groups in the scores ofTampa Scale for Kinesiophobia(TSK-11),Visual Analogue Scale(VAS),Chronic Pian Self-efficacy Scale(CPSS),and Oswestry disability index(ODI)were compared before and after the intervention.In addition,the rehospitalization rate and reoperation rate were compared between the two groups 6 months after discharge.Results After the intervention,the scores of TSK-11,VAS and ODI in the observation group were lower than those in the control group,The total score of CPSS and the scores of self-efficacy for pain management(PSE) and self-efficacy for coping with symptoms(CSE)in the observation group were higher than those in the control group.The difference was statistically significant(P＜0.05).In addition,the rehospitalization rate and reoperation rate in the observation group were lower than those in the control group.Conclusion COX healthy behavior interaction model can reduce the level of kinetophobia and pain in patients with kinetophobia after minimally invasive OVCF surgery,and promote the functional recovery of patients.
