Background and aim: The importance of cognitive resources was shown in dual task studies of postural control. However, there was no definite evidence on how verbal instructions influence the allocation of attention to postural control. Therefore, the objective of this study is to explore the effect of verbal instructions on postural performance.
Materials and Methods: this Cross-sectional study was performed in 20 young adults (23.95 ± 3.31). Parallel standing/ hard surface, parallel standing/ foam surface, tandem standing/ hard surface were used as postural tasks and the choice reaction time task were conducted as cognitive task. Dual- task performance was measured under three different instructions including to pay attention to cognitive task, to postural task, and equal attention to both tasks.
Results: Comparing the performance of postural tasks under three different instructions were conducted by One-way ANOVA and showed in parallel standing on hard surface (p=0.831), parallel standing on foam (p=0.433), tandem standing on hard surface (p=0.912) for path length of COP and instructions in parallel standing on hard surface (p=0.308), parallel standing on foam (p=0.414), tandem standing on hard surface (p=0.867) for mean velocity were not significant. Postural performance in single and dual task conditions was significant only in parallel standing/ foam surface (p=0.046).
Conclusion: various instructions could not influence the amount of attention allocated to automatic postural tasks.
