title: Effect of tongue strength training using the Iowa Oral Performance Instrument in stroke patients with dysphagia.
abstract: [Purpose] The aim of this study was to evaluate the effectiveness of a structured program of resistance training for the tongue in order to improve swallowing function in stroke patients with dysphagia. [Subjects and Methods] Twenty-seven stroke patients with dysphagia were randomly divided into two groups. The experimental group participated in a resistance-training program involving a 1-repetition maximum, with an intensity of 80%, along with 50 repetitions per day each for the anterior and posterior regions of the tongue. Both groups received conventional therapy for dysphagia for 30 min per day, 5 times per week, for 6 weeks. [Results] The experimental group showed statistically significant improvements in both, the anterior and posterior regions of the tongue. In contrast, the control group showed significant improvements only in the anterior region of the tongue. In the videofluoroscopic dysphagia scale evaluation, improvement was noted at both, the oral and pharyngeal stages in the experimental group, whereas significant improvements were only noted in the oral stage and total score in the control group. [Conclusion] Our study confirmed that tongue resistance training is an effective intervention for stroke patients with dysphagia, offering improved tongue muscle strength and overall improvement in swallowing.
