Effects of Augmented Reality based Dual-Task Proprioceptive Training on Postural Stability, Positioning Sensation and Cognition
This study compared augmented reality (AR)-based proprioception training to traditional therapy to determine if the two tasks together were effective in improving postural stability, proprioception, and cognition. Forty-five healthy adults in their 20s were randomized into three groups: AR-based DT, AR-based proprioceptive exercise, and therapist-supervised exercise. Paired t-test and independent t-test were used to determine the within and between group effects, and the three groups were subjected to one-way ANOVA and Bonferroni's post hoc analysis. For postural stability, stability index and postural stability improved post-intervention in all groups (p<.05), with no differences between groups (p>.05). positioning sensation improved in all groups (p<.05), with no difference between groups (p>.05). Cognitive parameters showed significant differences in recognition and calculation in all groups after the intervention (p<.05), and no significant differences in ordering (p<.05). Thus, AR-based interventions have shown similar effects to therapists, improving cognitive performance on both tasks, and can be selected in some cases.
