Research Abstract

The suprahyoid muscles raise the hyoid bone during swallowing and depress the mandible during mastication and speech. The present study aims to 1) develop the new muscle strengthening exercise for suprahyoid muscles using mouth opening movement and 2) investigate the effects of the mouth opening exercise for dysphagia patients. Compared to before starting the exercise, significant improvements were observed in the extent of anterior direction of the hyoid bone six weeks after initiating the exercise. The mouth opening exercise may be recommended as the treatment for effectively strengthening the suprahyoid muscles for dysphagia.
