Efficacy of transcutaneous auricular vagus nerve stimulation in treating patients with post-stroke motor disorders: a prospective study

taVNS is an effective and safe adjunctive therapy for post-stroke motor recovery. It enhances neuroelectrophysiological function, improves motor and daily living abilities, and favorably modulates biomarkers of neural injury and repair. The consistent correlations among functional, neurophysiological, and biochemical outcomes highlight an integrated recovery pathway, supporting the integration of taVNS into standard neurorehabilitation protocols.
