The inability to maintain balance under dual-task conditions is a common occurrence. Because impaired dual-task balance performance predicts adverse outcomes such as falls, and declines in both cognitive and physical function, interventions that improve dual-task balance performance are a critical health care need. Present work was performed on 90 young healthy volunteers, includes 56 females and 34 males, and they studied for change in their auditory reaction time (ART) and visual reaction time (VRT) with the concomitant use of mobile phones. Mean age of volunteers included in this work was 27.5 ± 5.75 years. Audio Visual Reaction Time Machine, RTM 608 was used to measure ART and VRT of subjects. Recording of the baseline reaction time while not using mobile phone, ART & VRT were measured when the subjects conversed on the mobile phone, in conventional hand held method and then later when they continued their conversation in the hands free mode. Obtained results showed that ART significantly increased from the baseline (p<0.01) in both hand held method and hands free mode i.e. 21.81% & 24.06% respectively. Both mental or cognitive disturbance due to multitasking and the subjects took remarkably longer time to take action to the auditory stimuli. The twin task recital, with both the modes of dialogue yielded no noteworthy disparity (p= 0.701), suggesting that the use of mobile phone per se, whether in hands free or hand held mode, equally impaired the auditory reaction time .
