Background: Aim of the study determine the effect of mobile phone on hand pain and muscle
strength.
Materials and methods: The measurements were taken from hand dynamometer for handgrip
strength and manual muscle tester for thumb muscle strength. The means of the right and left
handgrip strength, thumb muscle strength were measured.
Results: There was a statistically significant difference in height and weight measurements between genders (p<0.05). We found as using of mobile phone increased, hand strength increased.
However, the highest value of thumb muscle strength on the right and left sides was observed to
be over 8 hours. There was a high relation between gender and muscle strength measurements
(p<0.05; r=0.700). Also, 22.58% of mobile phone users complained about pain described in thumb
base.
Conclusion: This study revealed that the duration of mobile phone use affects on grip and thumb
flexion muscle strength.
