ABSTRACT
The use of smartphone has increased amongst all ages and it use during walking causes serious injuries. Understanding the motor control processes of gait while using a smartphone seems to be of high practical relevance. The aim of this study was to analyze the gait velocity while using a smartphone in young adults. Fifteen healthy young adults (age= 21.27±3.03 years, mean±SD) were recruited. The gait velocity was assessed in two conditions: walking at a normal pace and velocity (single motor task) and walking while texting on smartphone (motor dual-task), using the Qualisys® Motion Capture System. Compared to walking without using a smartphone, the subjects walked at slower velocity when using a smartphone (p<0.05). In conclusion, the use of smartphone has a negative impact on gait velocity, suggesting the risk of falls and injuries in young adults, also, can be an indicator of more evident gait changes in old age.
