Motor Imagery of Yips-Affected Pitching Enhances Corticospinal Excitability in Baseball Players with Yips

Purpose: Yips is a psycho-neuromuscular impediment disrupting the execution of sports skills. It remains unclear how the modulation of descending motor pathway activity differs between conditions with and without yips symptoms. This is attributable to (1) the difficulty in elicit...

Facilitating the supplementary motor area activity reduces variability of ball arrival position in accurate ball throwing performance

Maintaining high accuracy during rapid, dynamic movements is a significant challenge for the central nervous system. The supplementary motor area (SMA) is a key cortical region for orchestrating motor commands and regulating movement variability, yet its causal contribution to ma...
