Abstract

This study examined the effects that cell phone use has on gait and situation awareness. Subjects (n=18; 24.67±3.60 yrs) completed three five-minute treadmill walking conditions (self-selected speed): (1) CONTROL (walking only), (2) TALK (walking and talking), and (3) TEXT (walking and texting). The number of detected lights presented in the visual field was recorded, as were kinematic data of the feet. Using a one-way repeated measure ANOVA it was determined light detection (F (2,17) =39.777, p<0.001) and TCmin (F(2,17) =8.574, p=0.001) were different between conditions. Specifically, light detection decreased during TEXT (2.6±2.2 lights) versus TALK (5.8±0.05 lights, p<0.001) or CONTROL (5.9±0.05 lights, p<0.001); TCmin decreased during TALK (56.3±3.66 mm, p=0.002) and TEXT (56.1±4.481 mm, p=0.014) versus CONTROL (58.5±4.35 mm). It is concluded that a reduction in toe clearance and decreased light detection ability occurs while walking and using a cell phone.
