Background and Aims: Recently, the effects of modern rehabilitation equipment, especially virtual balance practice, has attracted the attention of clinical researchers. The purpose of the current study was to investigate the effect of virtual balance practice on the dynamic and static balance of athletes after knee joints reconstruction of the anterior cruciate ligament.
Materials and Methods: In the present clinical trial study, 30 patients were selected purposefully and randomly divided into two groups of control (n=15) and experimental (n=15). The experimental group performed rehabilitation practice prescribed by sports medicine specialists and virtual balance practice for 15 weeks, and the control group performed only equilibrium rehabilitation during this period. Before and after the interventions, the static balance and dynamic balance were evaluated using a Stabilometery device and Star Scursion Balance Test (SSBT), respectively. Data were analyzed using SPSS, version 22, running paired and independent sample t-test at a significance level of P=0.05.
Results: Comparison of static and dynamic balance indices that both groups had a significant statistical difference between pre-test and post-test in static (total COP sways, mediolateral COP sways, Anterio posterior Sways) and dynamic balance tests (p < 0.05). Moreover, pre-test to post-test mean differences for static balance values had significantly decreased (p < 0.01), but it increased for the dynamic balance (p < 0.01) compared with the control group.
Conclusion: According to the results, virtual balance exercises can be used as a challenging exercise that involves various stresses on several laps on ligation, musculoskeletal structures around the joints, and improves the balance and reduces knee ligament injuries, especially the anterior cruciate ligament.
