Feasibility of repetitive peripheral magnetic stimulation for dysphagia with reduced hyoid elevation: a report of two cases. Jpn J Compr Rehabil Sci 2019; 10: 42-46.Objective: This study aimed to investigate the feasibility of peripheral magnetic stimulation for dysphagia with reduced hyoid elevation.Methods: Two patients with dysphagia with reduced hyoid elevation received two to three sets of magnetic stimulation, each comprising thirty treatments lasting 2 s. This repetitive peripheral magnetic stimulation (rPMS) was performed for at least five days per week for a period of six weeks.Results: Both patients underwent rPMS for six weeks without any complications. After rPMS, the 82-year-old male patient with disuse syndrome after aspiration pneumonia (Case 1) showed improved muscle strength and hyoid elevation distance. The 47-year-old male patient with dermatomyositis (Case 2) demonstrated improved muscle strength and fatigue after rPMS; in addition, his neck stiffness was alleviated, which led to the alleviation of fatigue during meals.Conclusion: Our results suggest that rPMS is a feasible and novel option for the treatment of reduced hyoid elevation.
