The Effect of Mobile Phone on Hand Pain and Muscle Strength

Background: Aim of the study determine the duration of mobile phone use on handgrip strength and thumb flexion muscle strength.
Materials and method: The measurements were taken from hand dynamometer for handgrip strength and manual muscle tester for thumb flexion muscle strength. The means of the right and left handgrip strength, thumb flexion 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). 
Conclusion: This study revealed that the duration of mobile phone use has an effect on grip and thumb flexion muscle strength.
