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-yearold
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.
