Description
Mi and colleagues tested whether mouth and throat exercises change how the brain controls the tongue, work relevant to therapy used alongside sleep apnoea treatment. Twenty-two healthy adults, average age about 24, completed three sessions in the 2026 crossover study: breathing training, tongue training, and a no-training control. The team used magnetic pulses over the scalp to probe the tongue's motor area in the brain, plus a hand muscle as a comparison, and measured mouth pressures and airflow.
Tongue training clearly raised the brain's response from the tongue, with both response size and the responding area growing significantly. Breathing training and the control session did not. The hand muscle stayed unchanged under every condition, showing the effect was specific to the trained muscle. Pressures, airflow, and shape-recognition by mouth showed no differences. The authors read the change as an early adjustment in motor control rather than settled rewiring.
