The statistical analyses were performed by using SPSS for windows version 18.0, statistical software package. The value of p<0.05 was considered to indicate statistical significance. As the objective of this study was to find out the effects of PE, VR and BE on balance, cognitive function, muscle strength and fear of falling in the elderly. Two-way mixed ANOVA was used to test the variance differences among the four groups with post-hoc analysis as appropriately. Prior to utilization of statistical tests, descriptive statistics were performed and statistical assumptions were tested. Transformation will be performed if the data were not normally distributed. Appropriate statistical tests (parametric vs. non-parametric) were performed to determine the effects of different interventions in this study on balance, cognitive function, muscle strength and fear of falling in the elderly. Post-hoc power analysis was also performed.
