Electrostimulation of the neck portion corresponding to the thyroarytenoid-lateral cricoarytenoid (TA-LCA) complex for the treatment of spasmodic dysphonia (SD) and voice tremor (VT)

Introduction A 2013 review by Miller et al. reported electrostimulation has been assessed as a potential therapeutic tool for different types of laryngeal dystonia, including spasmodic dysphonia (SD) and voice tremor (VT), for about 40 years. The main problems, namely the characterization of the stimulation protocol and definition of outcome measures used as pass/fail criteria for the respective studies, were exacerbated by the lack of standardized diagnostic and therapeutic protocols for these conditions. We have developed a surface electrostimulation protocol applicable by SD and VT patients for daily home sessions.
