Background: Recently, smartphones have become a ubiquitous fixture of people's everyday lives. Many pedestrians use smartphones while routinely walking. Injurious accidents due to falling can happen when walking while using a smartphone. Objective: To investigate the height of the toes during the swing phase in individuals for comparison between normal walking and walking while reading using a smartphone. Participants: Participants were recruited from among university student volunteers. The study participants were 16 healthy young adults, 9 males and 7 females. Methods: The three dimensional motion analysis system (Vicon Nexus) was used for kinematic evaluations. Reflective markers were attached to the whole body on the Vicon Plug-in Gait Model, and the sampling frequency was 100Hz. The individuals walked barefoot over an approximately fourmeter walking path in the laboratory, walking normally then walking while reading using a smartphone. Instructions were given to each subject that walking speed should be maintained at a normal pace and should not intentionally be changed. Results: The following results were obtained. 1) Walking speeds while reading using a smartphone were significantly slower than those of normal walking. The cadence of walking while reading using a smartphone was significantly less than that of normal walking. The stride of walking while reading using a smartphone was significantly shorter than that of normal walking. 2) When walking while reading using a smartphone, despite the upper extremities and the torso moving unsymmetrically, the lower extremities moved symmetrically. 3) The maximum height of the toes during the swing phase of walking while reading was significantly lower than that of normal walking. At the maximum height of the toes, the value of the hip flexion range of motion for walking while reading using a smartphone was significantly smaller than that for normal walking.
