N2  - Background : The usage of tablet or media tablet computers have become a viable consumer alternative to traditional notebook (laptop) and desktop computing modes. The light weight of the tablet makes it with the users everywhere and the users spend many hours using it. Objective: This study was conducted to investigate the effect of tablet misuse on muscle performance of wrist and elbow. Methods: The current study was conducted on 60 normal subjects. They were assigned randomly into three equal groups (A) non tablet users, (B) using tablet for two hours daily and (C) using tablet more than four hours daily with their mean ages were (23±2.63), (22.8±3.01) and (23.4±2.47) years respectively. Peak torque of wrist extensors and elbow flexors were measured for the three groups using Biodex system 3 isokinetic dynamometer. Results: The results of the study revealed that there was a statistical significance difference in the peak torque of the right wrist extensors between group (A) and group (C) and between group (B) and group (C) at 120{u00B0}/sec but at 180{u00B0}/sec there was a statistical significance difference between group (A) and group (C) and there was no a statistical significance difference between group (B) and group (C). For the left wrist at both velocities there was a statistical significance difference between group (A) and group (C) and there was no a statistical significance difference between group (B) and group (C). For the peak torque of right and left elbow flexors there was a statistical significance difference between group (A) and group (C) and between group (B) and group (C) at both velocities
