In 30 seconds
This randomized controlled trial evaluated the efficacy of Pharyngeal Balloon Muscle Resistance Treatment (PBMRT) in 60 post-stroke patients with dysphagia. The intervention group showed significantly lower Fiberoptic Endoscopic Dysphagia Severity Scale (FEDSS) scores and higher Mann Assessment of Swallowing Ability (MASA) scores compared to the control group, indicating improved swallowing function.
Key findings
- PBMRT group had significantly lower FEDSS scores (W=305.50, p=0.029) than the control group.
- The intervention group achieved significantly higher MASA scores (t=2.23, p=0.030).
- Functional Oral Intake Scale (FOIS) levels were significantly higher in the PBMRT group (W=603.50, p=0.008).
- sEMG analysis showed significantly higher mean and peak amplitudes during swallowing tasks in the PBMRT group.
Why it matters
Dysphagia is a common complication after stroke, leading to serious health issues. This study suggests that PBMRT may enhance swallowing function, potentially improving patient outcomes and quality of life.
What to keep in mind
The study had a modest sample size and short intervention duration, with no long-term follow-up.
