Abstract

To compare efficiency index by bimanual coordination in smartphone addictors & non-addictors

Cross sectional observational data was collected from Professional students in the age group 18–25 years who uses smartphone more than 6 months. Smartphone addiction was assessed using scale-SV questionnaire. Among them 50 smartphone non addictors & 50 addictors. Bimanual coordination of upperlimbs was done by using two hand coordination test apparatus with electric chronoscope & efficiency index was calculated.

A Mann Whitney U test was conducted to determine whether there was a difference in the score of addiction & nonaddiction. From this data it can be concluded that there was a significantly higher score in smartphone addictors compared to nonaddictors (U=0.500, n1=n2=50, P < 0.001) The effect of smartphone addiction on efficiency index assessed by bimanual coordination were compared using an independent t test. Mean of efficiency index in smart phone non addictors & addictors was 78.90+17.04 & 53.70+18.06 (t=-7.17 p<0.001), which is statistically significant.

Motor efficiency in upper limb assessed by bimanual coordination in young adults is significantly decreased in smart phone addictors compared to the non-addictors.
