A Novel Approach to Severe Chronic Neurogenic Dysphagia Using Pharyngeal Sensory Electrical Stimulation.
Xue Zhang, Xiaolu Wang, Zulin Dou and 1 others
PMID 36194834WHAT IT FOUND
A single patient with severe post-surgical dysphagia who could not eat orally after 7 months of standard therapy began oral intake after 39 sessions of pharyngeal sensory electrical stimulation.
This is one case, not proof the treatment works for others.
Key findings
01The patient could take 200 mL of porridge orally after 39 sessions of pharyngeal sensory electrical stimulation.
02Swallowing function scores improved significantly after the stimulation treatment.
03Improvement continued after the stimulation stopped, but routine rehabilitation also continued.

What it does not show
This is a single case report without a control group, so it cannot establish that PSES caused the improvement. The patient continued receiving routine rehabilitation (tongue exercises, balloon dilation, therapeutic feeding) during and after PSES, making it impossible to separate the effect of PSES from these concurrent treatments. The authors state that the lack of improvement after 7 months of routine therapy and subsequent improvement after PSES suggests PSES was the main driver, but this is an inference from a single case. Long-term outcomes beyond 120 days are not reported.

The easy way to misread this
Do not assume PSES alone caused the recovery. The patient continued receiving tongue exercises, balloon dilation, and therapeutic feeding throughout the treatment and after PSES stopped. The contribution of any single component cannot be separated.
