简要总结
The tongue plays a central role in essential oral functions, including swallowing, speech, and upper airway control. Its coordinated interaction with the respiratory system is particularly relevant in clinical conditions such as obstructive sleep apnea and dysphagia. While respiratory muscle training is increasingly used in these contexts, its effects on the neural control of tongue function remain poorly understood.
This randomized cross-over pilot study aimed to investigate the acute effects of inspiratory (IMT) and expiratory (EMT) muscle training on tongue corticomotor excitability using transcranial magnetic stimulation. These results will provide novel insight into the neurophysiological mechanisms linking respiratory interventions and oral motor control.

结局指标
主要结局
Motor-evoked potentials
时间窗: Measured two times: immediately before the training session (baseline) and immediately after completion of the training session (approximately 45 minutes after baseline)
The amplitude of tongue-related motor-evoked potentials are assessed using transcranial magnetic stimulation over the tongue motor cortex.
次要结局
- Maximum Inspiratory and Expiratory Pressure(Measured two times: immediately before the training session (baseline) and immediately after completion of the training session (approximately 45 minutes after baseline))
- Tongue elevation peak pressure(Measured two times: immediately before the training session (baseline) and immediately after completion of the training session (approximately 45 minutes after baseline))
