Dual-tasking is common in daily life. One normally needs to maintain postural control while performing one or more other concurrent tasks such as walking while talking. When two tasks are being performed simultaneously, performance of one or both can be impaired; if together they require attention that exceeds an individual’s capacity. Dual-task methods have been successfully applied to the measurement of postural control.The study of relation between cognitive overload and upper limb motor task, and their respective effects on postural sway in quiet standing can be used to train phases of postural stability. Young adults between ages 18 and 35 who were able to count; excluding the subjects with recent lower limb pathologies, neurological or vestibular conditions were taken. Arbitrarily, 100 subjects were taken, and the sampling was convenient sampling. The subject stood on the force plate of the balance system with feet on either side of the midline of the force plate. For the first 10 seconds, the subject was asked to look straight and maintain balance. For the next 10 seconds, subject was asked to hold a glass full of water in his/her hands and maintain. For the next 10 seconds, subject was asked to count back by 3s from 100 (100, 97, 94, etc.). Three trials were taken for each task. The sway velocity was measured each time by the force plate censors. One way ANOVA showed that there was statistically significant difference in postural sway while performing cognitive task as compared to quiet standing (p<0.01); and cognitive task as compared to motor task (p<0.001). However, there was no statistically significant difference in postural sway between quiet standing and motor dual task (p>0.05). Hence it was concluded that increasing attentional demand by implementing a cognitive task had a greater influence on postural sway as compared to motor dual task and quiet standing.
