高压氧联合全身振动训练对膝关节交叉韧带损伤术后下肢肌力的影响

Effect of hyperbaric oxygen combined with whole body vibration training on lower limb muscle strength of patients after surgery on knee joint cruciate ligament injury

目的探讨高压氧(HBO)联合全身振动训练(WBV)对膝关节交叉韧带损伤术后下肢肌力的影响。方法选取在商丘市第一人民医院接受手术治疗的177例膝关节交叉韧带损伤患者作为研究对象,选取时间为2018年5月至2020年5月,按照随机数字表法分为联合组(HBO联合WBV)、HBO组、WBV组,每组59例,比较各组膝关节屈伸肌群峰力矩、Lysholm膝功能评分、视觉模拟评分(VAS)、轨迹误差(ATE)。结果重复测量方差分析显示,3组屈膝、伸膝峰力矩的时点效应、时点与组间的交互效应比较差异均有统计学意义(P<0.05),而组间效应比较差异无统计学意义(P>0.05)。3组Lysholm膝功能评分、VAS评分、ATE的时点效应、组间效应、时点与组间的交互效应比较,差异均有统计学意义(P<0.05);两两比较显示,干预前,3组屈膝、伸膝峰力矩比较差异无统计学意义(P>0.05);干预后,联合组的屈膝、伸膝峰力矩高于HBO组和WBV组(P<0.05)。术前,3组Lysholm膝功能评分、VAS评分、ATE比较,差异无统计学意义(P>0.05);术后1、3、12个月,联合组的Lysholm膝功能评分高于HBO组和WBV组,而ATE低于HBO组和WBV组(P<0.05);干预后1、2周,联合组的VAS评分低于HBO组和WBV组(P<0.05)。结论HBO联合WBV有利于改善膝关节交叉韧带损伤术后患者的下肢肌力。

Objective To investigate the effect of hyperbaric oxygen(HBO)combined with whole body vibration(WBV)training on lower limb muscle strength of patients after surgery on knee cruciate ligament injury.Methods A total of 177 patients with knee cruciate ligament injury who received surgery in the First People’s Hospital of Shangqiu from May 2018 to May 2020 were selected as research subjects.According to the random number table method,they were divided into HBO+WBV group,HBO group,and WBV group,with 59 cases in each group.The peak torques of knee flexion and extensor muscle group,Lysholm knee score,visual analogue scale(VAS)score,and absolute trajectory error(ATE)were compared among the groups.Results The repeated measures analysis of variance showed that the differences among time-point effects of peak torques of knee flexion and extensor muscle group in the three groups,and the differences between the time points and the between-group interaction effects of the three groups were all statistically significant(P<0.05),while the between-group effects among the three groups had no statistically significant difference(P>0.05).The differences among the three groups in terms of Lysholm knee score,VAS score,time-point effect of ATE,between-group effect,and the difference between time-points and between-group interaction effects were statistically significant(P<0.05).Post-hoc pairwise comparison showed that,before intervention,the three groups showed no significant difference in the peak torques of knee flexion and extensor muscle group(P>0.05);after intervention,the peak torques of knee flexion and extensor muscle group in the HBO+WBV group were higher than those of the HBO group and the WBV group(P<0.05);before surgery,the Lysholm knee scores,VAS scores,and ATEs of the three groups had no statistically significant difference(P>0.05);1,3,and 12 months after surgery,the Lysholm knee scores of the HBO+WBV group were higher than those of the other two groups,while the ATE of the HBO+WBV group was lower than those of the other two groups(P<0.05);1 and 2 weeks after the intervention,the VAS scores of the HBO+WBV group were lower than those of the other two groups(P<0.05).Conclusion HBO combined with WBV can improve the muscle strength of the lower limbs of patients after surgery on knee cruciate ligament injury.
