the Effect different type of dual task balance training on balance and cognitive function of older adults

The purpose of this research is to investigate the effectiveness of different training methods of dual task on balance and cognitive function in the elderly. The participants in this study were 36 elderly individuals aged 65 years and older, who met the research's entry criteria. The selected individuals were divided into three groups of 12 people each based on the pre-test Berg balance scores. The research groups included dual task balance training with fixed and variable priority and a control group. The Berg balance test was used to assess functional balance in the elderly, and the Serial reaction time test was used to assess cognitive function. Data analysis was conducted using covariance analysis and the Bonferroni post hoc test. The results of the data analysis showed that in the balance test, there was no significant difference between the control group and the dual task group with fixed and variable priority (P≥0.05). In addition, the serial reaction time test results showed that the dual task groups performed significantly better than the control group (P≤0.05), And the variable priority dual-task group had a significantly lower reaction time than the fixed priority dual-task training group (P≤0.05). The results of this research demonstrated that dual task training, particularly with variable priority, resulted in faster information processing in the elderly. Therefore, it appears that, in addition to the theory of limited attention capacity, other mechanisms such as the allocated attention ability can effectively impact balance and cognitive performance
