Enhanced Recovery of Post-Thyrodectomy Vocal Function Through Electrical Muscle Stimulation: A Physiotherapy Case Report

Abstract

Abstract Background: This case report investigates the effectiveness of Neuromuscular Electrical Stimulation (NMES) in the rehabilitation of vocal cord dysfunction following thyroidectomy. The surgical removal of the thyroid gland often results in complications such as recurrent laryngeal nerve injury, leading to vocal cord paralysis. This report focuses on a 14-year-old female patient who experienced significant voice impairment post-thyroidectomy. Objective: The study aims to evaluate the efficacy of NMES combined with soft tissue mobilization and task-specific vocal exercises in restoring vocal function. Methods: The intervention involved eight weeks of physiotherapy, with NMES applied to stimulate the vocal cord muscles, complemented by soft tissue mobilization using olive oil and structured vocal exercises. The Voice Handicap Index (VHI) was utilized to assess the impact of the intervention on the patient's vocal function, physical aspects, and emotional well-being. Results: The patient's VHI score improved dramatically from 95 (severe impairment) to 7 (minimal impairment) post-treatment. Significant improvements were noted across all VHI domains, highlighting enhanced vocal function and quality of life. Conclusion: This case underscores the critical role of physiotherapy in managing post-thyroidectomy vocal cord paralysis. The synergistic application of NMES and complementary therapies proved effective in restoring vocal function. These findings advocate for the integration of NMES into routine post-operative care.
