Electroacupuncture-Based Cerebral Electric Field Therapy for Unilateral Vocal Cord Paralysis with Secondary Dysphagia Post Upper Respiratory Infection.
Unilateral vocal fold paralysis secondary to peripheral nerve injury presents limited treatment options and inconsistent outcomes. This protocol describes an electroacupuncture-based cerebral electric field therapy designed to target neuroanatomically relevant pathways through combined scalp, posterior cervical, and anterior neck electroacupuncture. The procedure includes standardized point selection, stimulation parameters, and treatment sequencing, followed by objective functional assessment using laryngoscopy and videofluoroscopic swallowing study. In a representative case, the application of this protocol was associated with observable improvements in voice quality and swallowing function. Patients with unilateral vocal fold paralysis frequently experience hoarseness, dysphagia, aspiration, and reduced laryngeal sensation, leading to substantial functional limitations and decreased quality of life. This protocol demonstrates the feasibility of electroacupuncture-based cerebral electric field therapy as a structured intervention for unilateral vocal fold paralysis and provides a reproducible framework for future clinical exploration. Additional investigation may help clarify its potential role as a supportive therapeutic option. Future controlled studies may further evaluate its clinical effectiveness and applicability.
