Lee JH, Kim SB, Lee KW, Lee SJ, Lee JU - Ann Rehabil Med (2015)

Bottom Line: This study was designed as a matched comparative study.Group A showed significant improvement compared to group B in the DOSS score immediately and 4 weeks after rTMS.There were no significant differences in the changes of FDS and PAS scores between groups A and B immediately and 4 weeks after rTMS. rTMS over a hot spot for the suprahyoid muscle caused more improvement in swallowing function when compared to that over the interconnected site.

ABSTRACT

Objective: To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) according to the stimulation site in subacute stroke patients with dysphagia.

Methods: This study was designed as a matched comparative study. Twenty-four patients who had dysphagia after ischemic stroke were recruited, and they were divided into two groups after matching for age and stroke lesion. The patients in group A received rTMS over the brain cortex where motor evoked potential (MEP) was obtained from the suprahyoid muscle. Group B received rTMS over the brain cortex where MEP was obtained from the abductor pollicis brevis muscle. rTMS was performed at 110% of MEP threshold, 10 Hz frequency for 10 seconds, and then repeated every minute for 10 minutes. Dysphagia status was measured by the Functional Dysphagia Scale (FDS), the Penetration-Aspiration Scale (PAS), and the Dysphagia Outcome and Severity Scale (DOSS) using the results of a videofluoroscopic swallowing study. These evaluations were measured before, immediately, and 4 weeks after rTMS.

Results: Group A showed significant improvement compared to group B in the DOSS score immediately and 4 weeks after rTMS. There were no significant differences in the changes of FDS and PAS scores between groups A and B immediately and 4 weeks after rTMS.

Conclusion: rTMS over a hot spot for the suprahyoid muscle caused more improvement in swallowing function when compared to that over the interconnected site.

Treatment effects in (A) FDS, (B) PAS, and (C) DOSS scores. Group A showed significantly bigger increase in DOSS scores than group B both immediately after and 4 weeks after rTMS. ΔFDS, ΔPAS, ΔDOSS, amounts of changes from before rTMS. FDS, Functional Dysphagia Scale; PAS, Penetration-Aspiration Scale; DOSS, Dysphagia Outcome and Severity Scale; rTMS, repetitive transcranial magnetic stimulation; group A, rTMS over the cortex representing the suprahyoid muscle; group B, rTMS over the cortex representing the abductor pollicis brevis. *p<0.05.

Mentions: When the treatment effects from baseline to immediately after rTMS were compared between the two groups, there were no statistically significant differences in the degree of improvement in FDS or PAS scores; however, group A showed a statistically significant improvement in the DOSS score. Similarly, when the treatment effects from baseline to 4 weeks after rTMS were compared between the two groups, there were no statistically significant differences in the degree of improvement in FDS or PAS scores; however, group A showed a statistically significant improvement in the DOSS score (Fig. 4).
