Purpose : The purpose of this study figures out how the biofeedback exercise combined with a Shaker exercise and a jaw-opening exercise affects the suprahyoid muscle activation of stroke with a swallowing disorder.
Methods : The study period was from June, 2018 to September, 2018, to 45 patients who were suitable for selection criteria. Participants were divided into three groups: a visuoauditory biofeedback group (VABG), and a visual biofeedback group (VBG), and a self-exercise group (SG). The three groups were divided into the Shaker exercise and the jaw-opening exercise, and the biofeedback training by themselves. Three groups performed an intervention three times a day, five times a week, and four weeks long. Also, suprahyoid muscle activity was measured with a pre-test, a post-test and a follow-up test.
Results : To know the suprahyoid muscle activity after the intervention, there were statistically significant differences between the pre-test and the post-intervention(p< .01). All three groups showed the improvement with the mean comparing followed by VABG, VBG and SG. Comparing between the post- test and the follow-up test, all three groups showed the reduction of suprahyoid muscle activity with the mean comparing, followed VABG, VBG and SG.
Conclusion : It found that it was more effective when providing a double-sensory biofeedback than when training with a single-sensory biofeedback. Therefore, it is necessary to provide a multi-sensory input when applying the biofeedback in rehabilitation of the swallowing disorder.
