虚拟现实平衡训练对前交叉韧带重建术后膝关节功能的影响

Effect of virtual reality balance training on knee joint function after anteriorcruciate ligament reconstruction

目的探讨虚拟现实(VR)平衡训练联合常规康复对前交叉韧带(ACL)重建术后患者本体感觉和膝关节功能恢复的影响。方法将100例ACL重建术后患者随机分为对照组与观察组,每组50例。对照组采用常规康复,观察组在常规康复基础上实施VR平衡训练。治疗前后,观察并比较2组患者的本体感觉功能(膝关节角度重现差值、被动活动察觉阈值)和膝关节功能[国际膝关节评分委员会(IKDC)评分、Lysholm评分]。结果治疗后,2组膝关节角度重现差值、被动活动察觉阈值均低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05)。治疗后,观察组Lysholin评分、IKDC评分依次为(76.23±6.49)、(69.12±9.46)分,分别高于对照组的(71.41±7.23)、(65.22±9.47)分,差异有统计学意义(P<0.05)。结论VR平衡训练能够改善ALC重建术后患者本体感觉功能,并促进膝关节功能恢复。

Objective To investigate the effects of virtual reality(VR)balance training combined with routine rehabilitation on postoperative proprioception and knee joint function recovery in patients with anterior cruciate ligament(ACL)reconstruction.Methods A total of 100 patients after ACL reconstruction were randomly divided into control group(n=50)and observation group(n=50).The control group received routine rehabilitation,and the observation group received VR balance training on the basis of routine rehabilitation.Proprioceptive function(knee angle reappearance difference,detection threshold of passive activity)and knee function[International Knee Scoring Committee(IKDC)score,Lysholm score]before and after treatment were observed and compared between the two groups.Results After treatment,the knee angle reconstruction difference and passive activity detection threshold of the two groups were lower compared with those before treatment,and were lower in the observation group than those in the control group(P<0.05).After treatment,the Lysholin score and IKDC score in the observation group were(76.23±6.49)and(69.12±9.46),respectively,which were significantly higher than(71.41±7.23)and(65.22±9.47)in the control group,and the differences were statistically significant(P<0.05).Conclusion VR balance training can improve proprioceptive function of patients after ALC reconstruction and promote the recovery of knee joint function.
