ClinConnect Summary

This clinical trial is studying whether a simple measurement called the Grip-Asymmetry Index (GAI) can help predict wrist pain in professional e-sports athletes. The researchers want to see if there’s a difference in grip strength between gamers who experience wrist pain and those who don’t. To do this, they will measure how strong each hand is using a device called a Jamar dynamometer. The trial aims to identify a specific GAI value that could indicate a higher risk for wrist pain, taking into account other factors like how many hours they game each week, their body weight, and gender.

To be eligible for the study, participants must be professional gamers aged 18 to 30 who play at least 35 hours a week. They will be placed in one of two groups: those who report wrist pain during gaming (rated 3 out of 10 or higher) and those who report little to no pain (rated less than 3). Participants will undergo grip strength testing and answer questions about their gaming habits and health. This study is currently recruiting participants, and it’s important to note that individuals with certain medical histories or recent injuries may not qualify.
