Abstract
Using a mobile phone while doing another activity is a common dual-task activity in our daily lives. This study examined the effect of texting on the postural stability of young adults. Twenty college students were asked to perform static and dynamic postural stability tasks. Traditional COP and multivariate multiscale entropy (MMSE) were used to assess the static postural stability and the Star Excursion Balance Test (SEBT) was used to assess the dynamic postural stability. Results showed that (1) texting impaired postural stability, (2) the complexity index did not change much although the task conditions changed, and (3) performing texting is perceived to be more difficult.
Highlights
Using a mobile phone while doing another activity is a common example of dual-task activities that we often do just about anywhere
In the case of dynamic postural stability, reaching distance of the Star Excursion Balance Test (SEBT) was shorter during a texting condition
Total excursion, mean displacement velocity, and sway area were used to analyze the results based on traditional center of pressure (COP)
Summary
Using a mobile phone while doing another activity is a common example of dual-task activities that we often do just about anywhere. A study by Schwebel et al [6] found that listening to music and texting are more distracting than talking on the phone, because texting involves reading and typing: an activity which is more cognitively demanding than talking, while listening to music is a constant auditory disturbance [6]. These previous studies examined the distracting effect of using mobile phones. They only analyzed the behavioral effect of using mobile phones that may cause accidents
