Abstract:

Objective To explore the effect of composite electromagnetic stimulation combined with chin tuck against resistance (CTAR) on post-stroke dysphagia.

Methods From January, 2021 to December, 2023, 156 post-stroke patients with pharyngeal dysphagia in the First People's Hospital of Yibin were randomly divided into CTAR group (n = 51), neuromuscular electrical stimulation (NMES)+repetitive transcranial magnetic stimulation (rTMS) group (n= 52) and combination group (n = 53). On the basis of routine swallowing function training, they received CTAR, NMES+rTMS and NMES+rTMS+CTAR, respectively, for four weeks. They were assessed with Functional Oral Intake Scale (FOIS), Standardized Swallowing Assessment (SSA), Swallowing-Quality of Life (SWAL-QOL), Rosenbek Penetration Aspiration Scale (PAS), video fluoroscopic swallowing study (VFSS) (including the score of VFSS, pharyngeal transit time, and upward and forward displacement of hyoid bone), average surface electromyography (AMEG) of submental and hyoid muscles, before and after treatment.

Results The inter-group effect, intra-group effect and interaction effect were significant in SSA, SWAL-QOL and AMEG of the two muscles (F > 6.611, P < 0.001). The inter-group effect and interaction effect were significant in FOIS, VFSS, pharyngeal transit time, upward displacement of hyoid bone and forward displacement of hyoid bone (F > 3.451, P < 0.05). Pairwise comparison results showed that pharyngeal transit time was shorter in the combination group than in NMES+rTMS group (P = 0.048), forward displacement of hyoid bone was more in the combination group than in CTAR group (P = 0.002), and AMEG was higher in the combination group than in CTAR group and NMES+rTMS group (P < 0.001). There was significant difference in the score of PAS among three groups (Hc = 8.282, P= 0.016), and it was the best in the combination group.

Conclusion The combination of NMES+rTMS and CTAR is superior to single electromagnetic stimulation or CTAR in the treatment of post-stroke sysphagia.
