| Objective: The purpose of this paper is to investigate the effect of flossband training on knee function in patients after anterior cruciate ligament(ACL)reconstruction by collecting data on Lysholm score,thigh circumference,VAS pain score(visual analogue score(VAS)),knee joint mobility,quadriceps medial head thickness and quadriceps muscle strength before and after training,To analyse the effect of flossband training on the function of the knee joint in patients after ACL reconstruction,and to provide more efficient rehabilitation training for patients after ACL reconstruction,so as to help them get rid of the troubles caused by ACL injury as soon as possible and return to society and work as soon as possible.Methods: Thirty-six male patients who underwent ACL reconstruction at the Affiliated Sports Hospital of Chengdu Sports Institute were recruited and randomly divided into an experimental group(n=18)and a control group(n=18).2 groups of subjects underwent the intervention three times a week for a total of 8 weeks,with each intervention lasting 90 minutes.In the experimental group,the flossband training was added at 2 weeks postoperatively along with the conventional rehabilitation treatment,while the control group underwent conventional rehabilitation treatment only.The following indexes were collected at 2 weeks,6 weeks and 10 weeks postoperatively: Lysholm score,thigh circumference,VAS pain score,knee joint mobility,medial quadriceps head thickness,and quadriceps muscle strength at 6weeks and 10 weeks postoperatively,respectively.Statistical analysis was performed using SPSS 22.0 software,and paired-sample t-test was used to compare the differences in the indicators before and after the intervention,and independent-sample t-test was used to compare the differences in the indicators between the two groups,with the significance level p set at 0.05.Results:(1)Thigh circumference: intra-group comparison: compared to 2 weeks postoperatively,there was no statistical difference between the experimental and control groups at 6 weeks postoperatively(p > 0.05);at 10 weeks postoperatively,there was a significant increase in thigh circumference between the two groups with a significant difference(p < 0.05);and at 10 weeks postoperatively compared to 6weeks postoperatively,there was a significant difference in the experimental group(p< 0.05),while there was no statistical difference in the control group(p > 0.05).Comparison between groups: at 2 and 6 weeks postoperatively,there was no significant difference in thigh circumference between the experimental group and the control group(p > 0.05),and at 10 weeks postoperatively,the thigh circumference of the experimental group was significantly better than that of the control group(p <0.05).(2)Knee joint mobility: intra-group comparison: compared with 2 weeks postoperatively,there was a significant improvement in joint mobility between the control group and the experimental group at 6 weeks and 10 weeks postoperatively,with a significant difference(p < 0.05).Compared with 6 weeks postoperatively and10 weeks postoperatively,there was a significant improvement in joint mobility in both groups,and it was statistically significant(p < 0.05).Comparison between groups: at 2 weeks postoperatively,there was no significant difference in joint mobility between the two groups(p > 0.05).At 6 and 10 weeks postoperatively,the knee mobility in the experimental group was significantly higher than that in the control group and was statistically significant(p < 0.05).(3)Quadriceps muscle strength: intra-group comparison: compared with 6 weeks postoperatively,the peak knee extension moment was statistically significant in both the experimental and control groups at 10 weeks postoperatively(p < 0.05).Comparison between groups: At 6 weeks postoperatively,the peak knee extension moment in the experimental group was not significantly higher than that in the control group,and there was no statistical difference(p>0.05).At 10 weeks postoperatively,the peak knee extension moment in the experimental group was significantly higher than that in the control group,which was statistically different(p < 0.05).(4)Medial head thickness of quadriceps: Within-group results: there was no significant difference in the thickness of the medial head of the quadriceps in the control group at 2 weeks postoperatively,6 weeks postoperatively,and 10 weeks postoperatively when compared with each other(p > 0.05).There was no statistically significant difference in the thickness of the medial head of the quadriceps muscle in the experimental group at 6 weeks postoperatively compared to 2 weeks postoperatively(p > 0.05)and a significant difference at 10 weeks postoperatively(p< 0.05),while there was no statistically significant difference at 10 weeks postoperatively compared to 6 weeks postoperatively(p > 0.05).Results between groups: there was no statistical difference in the thickness of the medial head of the quadriceps muscle between the experimental and control groups at 2 weeks and 6weeks postoperatively(p>0.05),and at 10 weeks postoperatively,the thickness of the medial head of the quadriceps muscle in the experimental group was statistically significantly higher than that in the control group(p<0.05).(5)Knee function scores:(1)VAS pain scores: intra-group results: compared with 2weeks postoperatively,the VAS scores of the experimental and control groups were significantly lower at 6 weeks postoperatively,with statistically significant differences(p < 0.05).At 10 weeks postoperatively,VAS scores were significantly lower than those at 2 weeks postoperatively and 6 weeks postoperatively,with statistically significant differences(p < 0.05).Comparison between groups: VAS scores were not statistically significant in the experimental and control groups at 2 weeks postoperatively and 10 weeks postoperatively(p > 0.05).However,the VAS scores in the experimental group were significantly lower than those in the control group at 6weeks postoperatively,which was statistically significant(p < 0.05).(2)Lysholm scores: intra-group comparison: compared to 2 weeks postoperatively,Lysholm scores were significantly higher in the experimental and control groups at 6 and 10 weeks postoperatively,and were statistically different(p < 0.05).At 10 weeks postoperatively compared to 6 weeks postoperatively,Lysholm scores were significantly higher in both groups with a statistical difference(p < 0.05).Comparison between groups: at 2 weeks postoperatively,there was no significant difference in Lysholm scores between the experimental and control groups(p > 0.05).At 6 and 10 weeks postoperatively,the Lysholm scores of the experimental group were significantly higher than those of the control group,and the data were statistically different(p < 0.05).Conclusion:(1)flossband training combined with conventional rehabilitation can effectively improve thigh circumference,medial quadriceps head thickness,and quadriceps muscle strength after ACL reconstruction,and its improvement effect is significantly better than that of the conventional rehabilitation group.(2)flossband training combined with conventional rehabilitation can more rapidly improve knee function and joint mobility after ACL reconstruction,and its effect is better than that of conventional rehabilitation group,which can shorten the rehabilitation process and improve patients’ quality of life. |
