Understanding how shoulder movement affects pitching in baseball players

Cortical Processing of Proprioception Related to Pitching Performance in Baseball Players With Glenohumeral Internal Rotation Deficit

National Taiwan University Hospital · NCT06704529

This study is testing how shoulder movement affects pitching performance in baseball players with a specific shoulder issue to see if it impacts how fast and accurately they can throw the ball.

What this trial studies

This study investigates the relationship between cortical activity and proprioceptive acuity in baseball players who have a glenohumeral internal rotation deficit (GIRD). It aims to assess how these factors correlate with pitching performance by measuring ball velocity and accuracy. Proprioception will be evaluated through active joint reposition sense of the shoulder, while cortical activity will be recorded using electroencephalography (EEG). The findings could provide insights into the central nervous system's role in proprioception and its impact on athletic performance.

Who should consider this trial

Good fit: Ideal candidates are active baseball players with at least one year of experience who train or compete for a minimum of three hours per week.

Not a fit: Patients with current upper extremity pain or a history of significant upper extremity injuries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of how proprioception affects pitching performance, potentially leading to improved training and rehabilitation strategies for baseball players.

How similar studies have performed: While the specific approach of this study may be novel, similar studies have shown that understanding proprioception can significantly impact athletic performance.
