Summary

Objective: To investigate the clinical efficacy of transcranial direct current stimulation (tDCS) combined with intraoral electrical stimulation in patients with dysphagia after pontine infarction. Methods: This prospective study enrolled a total of 90 patients with dysphagia due to pontine infarction from October 2022 to November 2024, and they were divided into three groups according to the treatment method: control group A, control group B, and experimental group C. Control group A was given intraoral induction electrical stimulation, control group B was given transcranial direct current stimulation (tDCS), and experimental group C was given tDCS combined with intraoral induction electrical stimulation. The three groups were compared in terms of efficacy, modified Waffield Drinking Water Test Score (MWST), Penetration-aspiration scale (PAS), Functional Oral Intake Scale (FOIS), Hyoid-Larynx Complex mobility, maximum amplitude of surface electromyography, and swallowing time.

Conditions

  • Pontine Infarction

Interventions

DEVICE

Intraoral induction electrical stimulation therapy

Intraoral induction electrical stimulation therapy (specific method\[13\]: hand-held electrode rods were used to stimulate the mandibular hyoid muscle, digastric muscle, anterior abdomen, and other muscles of the three groups. Parameter setting: the frequency is 80Hz, the wave width is 1ms, the intensity is set to the muscle contraction, each electrical stimulation is 3s, intermittent 10s, 20min/time, 1 time/day, 5 days/week, 4 weeks is limited.

DEVICE

tDCS treatment

tDCS treatment (specific method: microcurrent stimulator, stimulation electrode (3 cm×4 cm gelatin sponge), anodic stimulation site is the pharyngeal sensorimotor cortex area (between C3/T3 on the left\[14\], between C4/T4 on the right); the supraorbital area is the site of cathodic stimulation. The direct current intensity is 2.0 mA (20 min/time, 2 times/day) for two treatments (respectively, yin and yang alternating treatment), with an interval of at least 1 h, 5 days/week, and 4 weeks.

DEVICE

tDCS combined with intraoral induction electrical stimulation

tDCS combined with intraoral induction electrical stimulation. The patients were first treated with tDCS (the method is the same as that of the control group B) for 20 people twice a day and then given intraoral induction stimulation (the specific method is the same as that of the control group A) for 20 minutes, once a day, for 4 weeks.
