Purpose: To determine whether differences in pinch strength exist between internet gaming addicts and non-addicts. Methods: Thirty university students participated in this study and were classified according to the severity guidelines of the Young's Internet Addiction Test. Fifteen participants with addiction were selected as the experimental group and 15 non-addicts were selected as the control group. Both groups were evaluated for pinch strength using a Preston pinch gauge. The participants performed all pinch-strength tests in a seated position, as recommended by the American Society of Hand Therapists. Both hands were divided into dominant and non-dominant hands according to pinch strength. The results were analyzed using an independent t-test. Results: Results indicated that key and tripod pinch strengths were significantly different between the dominant and non-dominant hands between the two groups. Conclusion: This results show that the potential risk of musculoskeletal diseases can be predicted in advance based on pinch-strength test results.
