Abstract

Effect of smart phone using duration and gender on dynamic balance

Smart phones are constantly used for extended periods while looking at the visual display terminals this may causes musculoskeletal problems. So, the purpose of this study was to investigate effect of smart phone using duration and gender on dynamic balance.
Subjects: Sixty normal subjects included in this study their age ranged from 20 years to 35 years were divided into three groups, A not using smart phone, B using smart phone less than 4 h per day, C using smart phone more than 4 h per day.
Methods: Biodex Stability System was utilized to assess dynamic balance; 3 trials were performed from which the mean value was calculated.
Results: there is a significant decrease in all balance directions for group B and C (using smart phone) with favor reduction for group C (using smart phone more than 4 h per day) and there is a significant difference between male and female subjects as dynamic balance decreased more in female subjects more than male subjects.
Conclusion: Long duration of smart phone using affect negatively the balance ability especially in females, so we should develop preventive programs to alleviate its negative effects.
