Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This cross-sectional study investigates whether a simple Grip-Asymmetry Index (GAI) can predict self-reported wrist pain in professional e-sports athletes. Professional gamers (aged 18-30) who play at least 35 hours per week will be assessed using a Jamar dynamometer to measure maximal grip force in both hands. The study will compare GAI between two groups: those with wrist pain (≥3/10 on Visual Analog Scale during play) and those without pain. A GAI cutoff value for predicting wrist pain risk will be established through ROC analysis, with additional factors such as gaming hours, BMI, and sex incorporated into a multivariable logistic regression model.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pain Group

Professional e-sports athletes reporting wrist pain ≥3/10 on VAS during play

Pain Group

Intervention Type OTHER

Professional e-sports athletes who report wrist pain rated at 3 or higher on a 10-point Visual Analog Scale during gaming activities. These participants play video games professionally for at least 35 hours per week, are between 18-30 years old, and have no history of neurologic or rheumatic disease.

No-Pain Group

Professional e-sports athletes reporting minimal to no wrist pain (\<3/10 on VAS during play)

No-Pain Group

Intervention Type OTHER

Professional e-sports athletes who report minimal to no wrist pain (less than 3 on a 10-point Visual Analog Scale) during gaming activities. These participants play video games professionally for at least 35 hours per week, are between 18-30 years old, and have no history of neurologic or rheumatic disease.
