Relationships between magnitude of handedness and bilateral asymmetry of shoulder muscle activation during a unilateral overhead fatiguing task in right-handed individuals

Key Points

• As shoulder muscle activation increases, handedness plays a significant role in bilateral asymmetry.
• The maximum activation measured was observed during a fatiguing unilateral overhead task.
• Observational analysis determined muscle response variation across tasks in right-handed individuals.
• Results suggest a need for tailored rehabilitation strategies based on handedness and muscle activation patterns.
