Abstract
OBJECTIVE: This study was conducted to explore the potential use of neuromuscular electrical stimulation as an adjunctive treatment for muscle tension dysphonia.
METHODS: Voice data and ratings of fatigue and soreness were obtained for two experiments. Experiment one examined the vocal effects of neuromuscular electrical stimulation applied to the neck for 15 minutes. Experiment two examined the recovery effect of laryngeal neuromuscular electrical stimulation following a vocal loading task among normophonic women.
RESULTS: No significant differences in vocal function following 15 minutes of laryngeal neuromuscular electrical stimulation were found. Six of 11 participants receiving laryngeal neuromuscular electrical stimulation exhibited improved recovery following the vocal loading task.
CONCLUSION: A short session of laryngeal neuromuscular electrical stimulation may be beneficial in reducing muscle fatigue for some individuals. Further investigation is warranted to determine the applicability of laryngeal neuromuscular electrical stimulation in voice therapy.
