| Objective:To explore the clinical effect of blood flow restriction training(BFRT)applied to early rehabilitation training of patients after anterior cruciate ligament reconstruction(ACLR),and provide reference for early rehabilitation nursing of patients with ACLR.Methods:Through literature review,expert consultation and pre-experiment,the intervention program of blood flow restriction training for patients with ACLR was developed.Using the actual sampling method,from January 2022 to December 2022,80 patients with ACLR who met the screening criteria in the orthopedics department of Nanchang Third Class Hospital were selected as subjects,and were divided into a study group and a control group according to the admission order,with 40 patients in each group.The control group received traditional rehabilitation treatment,and the experimental group added a BFRT intervention plan to the control group.The two groups of patients were evaluated with the Lysholm Knee Function Scale,Soft Skin Thigh Circumference Scale,Knee Movement Scale,Visual Analogue Pain Scale(VAS),and SF-36 Compact Health Scale before,4 weeks after,and 8 weeks after intervention,respectively.After 4 and 8 weeks of intervention,the compliance of rehabilitation exercise of patients in the two groups was evaluated by the Orthopedic Patients’ Functional Exercise Compliance Scale.SPSS22.0 was used for data analysis.Results:1.Comparison of general data of the two groups of patients:a total of 80 subjects were included in the study,3 cases(37 cases)in the test group and 2 cases(38 cases)in the control group,and 75 effective cases were finally obtained.The two groups of general data(demographic statistics,disease-related data)were compared and analyzed,and there was no statistical difference(P>0.05),which was comparable.2.Before the intervention,there was no statistical difference in Lysholm knee function score between the two groups(P=0.649);At different time points after the intervention,the knee function scores of the two groups were improved,and the scores of the patients in the experimental group were significantly higher than those in the control group,the difference was statistically significant(P<0.05).The changes of Lysholm knee function score of the two groups of patients at three time points before,4 weeks after and 8 weeks after the intervention were compared by repeated measurement analysis of variance.The results showed that there was a time effect(F=138.117,P<0.001)and an inter-group effect(F=39.457,P<0.001)between the two groups of patients at different time points,and there was an interaction effect between time and groups(F=16.801,P<0.001).The Lysholm knee function score of the two groups of patients at different time points was compared in pairs within the group.The results showed that the difference was statistically significant(P<0.05).3.Before the intervention,there was no statistical difference in the difference of thigh circumference between the two groups(P=0.310);At different time points after the intervention,the difference of thigh circumference in the experimental group was significantly lower than that in the control group(P<0.05).The changes of thigh circumference difference between the two groups at three time points before,4 weeks after and 8 weeks after the intervention were compared by repeated measurement analysis of variance.The results showed that there were time effects(F=72.000,P=0.008),inter-group effects(F=85.111,P<0.001)and interaction effects(F=13.755,P<0.001)in the comparison of thigh circumference difference between the two groups at different time points.The difference of thigh circumference between the two groups at different time points was compared and analyzed in pairs within the group,and there was statistical difference(P<0.05).4.Before the intervention,there was no statistical difference in the range of motion of the affected knee between the two groups(P=0.638);At different time points after the intervention,the joint activity of patients in the experimental group was significantly higher than that in the control group,showing a statistical difference(P<0.05).The changes of the affected knee joint activity of the two groups at three time points before the intervention,4 weeks after the intervention and 8 weeks after the intervention were compared by repeated measurement analysis of variance.The results showed that there were time effects(F=72.001,P<0.001),inter-group effects(F=55.244,P<0.001)and interaction effects(F=17.099,P<0.001)on the changes of the affected knee joint activity of the two groups at different time points.The range of motion of the affected knee joint of the two groups at different time points was compared in pairs within the group,and there was statistical difference(P<0.05).5.Before intervention,there was no statistical difference in VAS scores between the two groups(P>0.05);At different time points after the intervention,the VAS scores of patients in the experimental group were significantly lower than those in the control group,showing a statistical difference(P<0.05).The changes of VAS scores of patients in the two groups at three time points before,4 weeks after and 8 weeks after the intervention were compared by repeated measurement analysis of variance.The results showed that there were time effects(F=961.433,P<0.001),inter-group effects(F=76.643,P<0.001)and interaction effects(F=16.801,P<0.001)in the changes of VAS scores of patients in the two groups at different time points.The VAS scores of the two groups of patients at different time points were compared in pairs within the group,and there were statistical differences(P<0.05).6.Before intervention,there was no statistical difference in the total mean score of SF-36 between the two groups(P>0.05);At different time points after the intervention,the total mean score of SF-36 in the experimental group was significantly higher than that in the control group,showing a statistical difference(P<0.05).The total mean score of SF-36 in the two groups at three time points before,4 weeks after and 8 weeks after the intervention was compared with the total mean score of SF-36 by repeated measurement analysis of variance.The results showed that there were time effects(F=24.226,P<0.001),inter-group effects(F=45.325,P<0.001)and interaction effects 053,P<0.001)in the change of the total mean score of SF-36 in the two groups at different time points.The total mean score of SF-36 in the two groups at different time points was compared in pairs within the group,and there was statistical difference(P<0.05).7.At 4 and 8 weeks after intervention,there was no statistically significant difference in exercise compliance scores between the experimental group and the control group,and the scores were higher than those of the control group(P<0.05);The exercise compliance score of the control group patients decreased significantly over time,and there was a statistical difference between the pre and post comparisons(P=0.003)。Conclusion:1.BFRT can significantly improve the Lysholm knee function score of patients with ACLR in the early postoperative period,which is of great significance to improve the knee function in the early postoperative period.2.BFRT can effectively increase the range of motion of the knee joint at the early stage after the operation of ACLR,reduce the circumference difference of the thigh on the healthy side,reduce the postoperative pain of the patients,improve the quality of life of the patients after the operation and the compliance behavior of rehabilitation exercise,and can be used as a safe and effective intervention method in the early rehabilitation of the patients after the operation of ACLR. |
