Hand-Held Dynamometer Assessment: E-Sports Grip-Asymmetry Index as a Predictor of Wrist Pain
- Conditions
- Wrist Injuries
- Registration Number
- NCT06978426
- Lead Sponsor
- Ahram Canadian University
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Grip-Asymmetry Index (GAI) Measured once at study enrollment The Grip-Asymmetry Index is calculated as (Dominant hand grip strength - Non-dominant hand grip strength) / Dominant hand grip strength × 100%. Grip strength is measured in kilograms using a calibrated Jamar hand-held dynamometer following standardized testing protocols. Higher GAI values indicate greater asymmetry between dominant and non-dominant hands.
- Secondary Outcome Measures
Name Time Method Maximal grip force in dominant hand Measured once at study enrollment Maximum grip strength measured in kilograms using a calibrated Jamar hand-held dynamometer following standardized testing protocols
Maximal grip force in non-dominant hand Measured once at study enrollment Maximum grip strength measured in kilograms using a calibrated Jamar hand-held dynamometer following standardized testing protocols
Wrist pain intensity during gaming Assessed at study enrollment, reflecting current pain experience during gaming activities Self-reported wrist pain measured using a Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (worst pain imaginable) during typical gaming sessions
Weekly gaming hours Assessed at study enrollment, reflecting average from the past month Self-reported average number of hours spent gaming per week
