Abstract

Abstract



Purpose

The aim of the present study was to study the effect of virtual reality exercises on fear of re-injury and movement pattern modification in people with ACL injury of the knee joint.

Methods

The statistical population of this research was all girls with ACL injury in Tehran city with an age range of 18-25 years. Before and after the fear of re-injury training protocol, Tempa's fear of re-injury questionnaire and landing error scoring system test were used to evaluate movement pattern correction. The training protocol was carried out for six weeks in the experimental group. In order to check the intra-group difference, paired t-test was used, and to check the difference between groups, analysis of covariance test was used at the error level of 0.05 using SPSS software.

Results

The results of the paired t-test showed that in the experimental group before and after participating in the virtual reality training course, in the variable of fear of re-injury (P=0.001, t=7.632) and modification of the movement pattern (P=0.001) , t=3.506) there was a significant difference, but no significant difference was observed in the control group (P<0.05).

Conclusion

In general, the results of this study show the importance of using virtual reality exercises in improving the jump-landing pattern and reducing the fear of re-injury in female athletes with ACL injuries.
