Prospective study shows taVNS enhances recovery in patients with post-stroke motor disorders, suggesting a new intervention approach.

To assess the therapeutic effects of transcutaneous auricular vagus nerve stimulation on functional recovery in post-stroke motor disorders.
Randomized controlled trial involving 139 patients with post-stroke motor disorders.
Participants assigned to taVNS or conventional rehabilitation groups.
Comprehensive assessments conducted at baseline and after a 4-week intervention.
Outcome measures included neurophysiological parameters, clinical evaluations, and serum biomarkers.
The taVNS group showed significantly shorter motor evoked potential latency and higher amplitude post-intervention.
Improvements observed in clinical scores (ARAT, FMA-UE, MBI) were significantly greater in the taVNS group.
Increased brain-derived neurotrophic factor levels and decreased S100-β levels in the taVNS group compared to the rehabilitation group.
Significant correlations found between functional scores and biomarker levels, indicating integrated recovery.
