Abstract:

Objective To investigate the effect of virtual reality balance training on knee proprioception after anterior cruciate ligament reconstruction (ACLR).Methods From January, 2016 to December, 2018, 72 patients after ACLR were randomly divided into control group (n = 36) and observation group (n = 36). On the basis of routine rehabilitation, they received routine balance training and balance training with virtual reality, respectively, for eight weeks. Before and after training, the center of pressure (COP) time stability, the COP speed (COPS) of closed eyes, the COPS of one leg, the knee joint reaction time, the center of pressure area (COPA) and the active joint angle recurrence deviation were measured.Results After training, the COP time stability, the COPS of closed eyes, the COPS of one leg, knee joint reaction time, COPA and active joint angle recurrence deviation improved in both groups (|t|>5.611,P < 0.001); and the COP time stability, the COPS of closed eyes, the COPS of one leg, the knee joint reaction time and active joint angle recurrence deviation were better in the observation group than in the control group (| t| > 3.232, P < 0.01), however, no significant difference was found in COPA between two groups ( t = 1.054, P = 0.296).Conclusion Virtual reality balance training can improve the proprioception of knee joint after ACLR, which is better than routine balance training.
