| Research Abstract |
The evaluation of respiratory muscle strength is of clinical importance for pulmonary rehabilitation in the patient with chronic respiratory disease and neuromusclar disease. In this study, we measured nasal expiratory pressure and expiratory muscle (transversus abdominis muscle : TA) and upper airway muscle (genioglossus : GG) EMG activities using fine wire electrodes during reverse sniff, a maneuver akin to "blowing your nose". TA and GG EMG activities increased with stepwise increments in nasal expiratory pressure during reverse sniff (R-SNEP) significantly.
We conclude that R-SNEP corresponds to the activity of the expiratory muscle and that this simple maneuver is useful for assessment of expiratory muscle strength. Also, upper airway muscle (GG) contributes for producing R-SNEP.
