Cover Story: This pilot study explored how diaphragmatic function influences iliopsoas muscle activity in individuals with chronic ankle instability (CAI). Eleven participants performed maximal isometric hip flexion under different breath-holding conditions. Surface electromyography revealed that iliopsoas activity on the affected side was significantly lower during end-inspiration, while other hip flexors showed no differences. These findings suggest that impaired diaphragmatic function may suppress iliopsoas activation and disrupt lumbopelvic coordination. Integrating breathing control and core stability training may thus enhance neuromuscular rehabilitation in CAI. View this paper
