title: Repetitive Peripheral Magnetic Stimulation With Intensive Swallowing Rehabilitation for Poststroke Dysphagia: An Open-Label Case Series.
abstract: OBJECTIVE
  The purpose of this pilot study was to determine the safety and feasibility of a six-day protocol of in-hospital repetitive peripheral magnetic stimulation combined with intensive swallowing rehabilitation (rPMS-ISR) for poststroke dysphagia.
  
  
  METHODS
  The subjects were eight patients with dysphagia caused by bilateral cerebral infarction (age: 62-70; time from onset of stroke: 27-39 months). rPMS was applied to the suprahyoid muscles, at strength set at 90% of the minimal intensity that elicited pain with a parabolic coil. One train of stimuli comprised 20 Hz for 3 sec followed by 27-sec rest. A single session included delivery of repetitive 20 trains of stimuli over 10 min, followed by 20 min of swallowing rehabilitation. Each patient received this combination treatment twice daily, morning and afternoon, over six consecutive days. Swallowing function was evaluated before and after intervention.
  
  
  RESULTS
  rPMS-ISR induced significant improvement in swallowing ability, laryngeal elevation delay time, penetration aspiration scale, and swallowing quality of life (p < 0.01), but had no significant effect on the functional oral intake scale.
  
  
  CONCLUSIONS
  The six-day in-hospital RPMS-ISR protocol seems safe and feasible for poststroke patients with dysphagia. The combination protocol improved swallowing function. Further larger studies are needed to confirm its efficacy.
