Usage of smartphones while performing dual tasks causes distraction. It has shown negative influence on standing postural balance and gait. This study aims to explore the influence of texting on mobility and proprioception in younger adults. Forty young adults participated in this study. Each participant was assessed for mobility using TUG test & Proprioception using Bosu Ball. A standard protocol of texting was prepared & the participant had to walk a distance of 3 meters first without texting and then with texting a standard protocol on his/her smartphone. Proprioception was assessed by evaluating the sway while the participant stood on a foam surface (Bosu Ball) first without texting and then with texting a standard protocol on his/her smart phone. The influence of texting on mobility and proprioception was highly significant (p<0.000). The results interpreted that there is difficulty in maintaining postural sway while standing on a foam surface with texting. Also, the results showed reduce mobility when the participant was texting on smartphone. In conclusion, there is a significant reduction in mobility and proprioception when an individual is performing a dual task of texting. This further affects the awareness of surroundings. To sum up, the purpose of this study is to correlate dual task with smartphone to proprioception and mobility which is satisfied successfully.
