This single-center, randomized, assessor-blinded study evaluated low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with sensory arousal nursing versus routine nursing in 160 patients with acute ischemic stroke, dysphagia, and feeding-related upper-limb dysfunction. Over 2 weeks, the combined intervention was associated with a greater improvement in Standardized Swallowing Assessment scores: the between-group difference in change was -3.9 points (95% CI, -5.8 to -2.0; p < 0.001). Differences also favored the combined intervention on oral intake and penetration-aspiration scale scores, but the findings do not establish clinically important swallowing benefit or reduced pneumonia risk.
Key findings
- The between-group difference in Standardized Swallowing Assessment change was -3.9 points (95% CI, -5.8 to -2.0; p < 0.001).
- Functional Oral Intake Scale change differed by 0.8 levels between groups (95% CI, 0.4 to 1.2; p < 0.001).
- Among participants with paired instrumental assessments, Penetration-Aspiration Scale change differed by -0.9 points (95% CI, -1.5 to -0.3; p = 0.004).
- Aspiration pneumonia occurred in 5/80 versus 11/80 participants (p = 0.118); no serious rTMS-related adverse events were reported.
Why it matters
The study provides randomized evidence that a coordinated rehabilitation protocol combining rTMS and sensory arousal nursing can produce short-term differences in swallowing-related scale scores after acute ischemic stroke. However, scale changes alone do not establish a clinically important benefit, and the pneumonia comparison did not demonstrate a statistically significant difference. The results help frame the potential and uncertainty of this combined approach.
What to keep in mind
The study was single-center with 2 weeks of follow-up. It evaluated a combined intervention, so the individual effects of rTMS and sensory arousal nursing cannot be determined; instrumental assessment results were available only for a subset.
