Introduction: Grip and pinch strength are the most important factors affecting the performance of hand and evaluating them as an indicator of activity, illness and performance is important. The aim of this study is to survey the relationship between the use of smart phones with the grip and pinch strength and the pain in students.
Methods: 350 students (212 female and 138 male) entered the study. The grip and pinch strength including tip, key and palmer pinch of dominant hand was measured 3 times with hydraulic dynamometer and Pinch Gauge. The pain in areas of the upper extremity (shoulder, elbow, forearm, wrist, fingers, thumb and neck) was evaluated with Visual Analog Scale (VAS). Data analysis was performed using SPSS 21 statistical software.
Results: Smartphone use and pain in the thumb, neck, arm, forearm, wrist and fingers relation was not statistically significant (P>0.05). Smartphone use and grip and pinch strength did not show statistically difference as well (P>0.05).
Conclusion: Although result of this study show no relation between smart phone use and grip, pinch and pain in upper limb and neck, but according to previous studies, using the Smartphone will cause muscle fatigue. Also duration of Smartphone use is determinant.
