RESUMEN
Objective:To evaluate the influence of wearable devices on rehabilitation effect of patients after knee arthroplasty by using Meta-analysis method.Methods:Computer retrieval was performed on China National Knowledge internet(CNKI),Wanfang database,China science and technology journal database(VIP),PubMed and Cochrane Library databases to search the randomized controlled trials(RCTs)of applying wearable devices in the rehabilitation management of patients after knee arthroplasty during the period between March 2010 and July 2022.Two researchers independently screened literatures,evaluated quality and extracted documents according to the inclusion and exclusion criteria in this research.The Stata12.2 software was used to conduct Meta-analysis on the qualified literature.The Hospital for Special Surgery(HSS)knee function score,knee range of motion(ROM),Western Ontario and McMaster Universities Arthritis Index(WOMAC)score,Timed Up and Go Test(TUGT)assessment,postoperative steps and Visual Analogue Scale(VAS)score were selected as outcome indicators.Results:A total of 8 literatures were included finally in the meta-analysis.The 8 studies of 8 literatures involved 718 patients who underwent knee arthroplasty,of which included 359 cases who adopted wearable devices to conduct rehabilitation intervention after surgery in the observation group and 359 cases who adopted routine discharge rehabilitation guidance in the control group.Compared with the control group,the postoperative rehabilitation intervention with wearable device of observation group could improve ROM score(SMD=0.64,95%CI:0.13～1.15,P<0.05),TUGT score(SMD=-0.39,95%CI:-0.75～-0.03,P<0.05),WOMAC score(SMD=1.37,95%CI:0.92-1.82,P<0.05)and postoperative steps(SMD=0.56,95%CI:0.13～0.98,P<0.05).However,the differences of HSS score(SMD=0.22,95%CI:-0.64～1.07,P>0.05)and VAS score(SMD=0.18,95%CI:-1.10～0.75,P>0.05)between two groups were not significant.Conclusion:The application of wearable devices in rehabilitation of postoperative patients who undergo knee arthroplasty can significantly improve the ROM,TUGT assessment,WOMAC score and the postoperative steps of patients,and can improve the knee joint function of patients,and can promote the rehabilitation of knee function of patients after knee arthroplasty.
