〔Abstract〕 Objective To summarize the best evidence of postoperative rehabilitation exercise in patients with pelvic fracture,and to explore the value of evidence. Methods A total of 148 patients with pelvic fracture admitted to the First People's Hospital of Shangqiu from December 2018 to December 2020 were selected as the research objects, and they were divided into a control group and an observation group by random number table method, with 74 cases in each group. Patients in the control group were given routine nursing, and patients in the observation group were given the best evidence of postoperative rehabilitation exercise based on the routine nursing, and the rehabilitation exercise compliance, rehabilitation effect and complications of patients in the two groups were observed and compared. Results After intervention, the compliance rate of rehabilitation exercise in the observation group was significantly higher than that in the control group, with statistical significance (P < 0.05). The total incidence of complications in observation group was significantly lower than that in the control group, the difference was statistically significant (P < 0.05). The effective rate of rehabilitation in the observation group was significantly higher than that in the control group, the difference was statistically significant (P < 0.05). Conclusion The best evidence summary intervention of postoperative rehabilitation exercise is applied to the nursing of patients with pelvic fracture, which can significantly improve the compliance and rehabilitation efficiency of patients with rehabilitation exercise, reduce the incidence of complications.
