Study Summary

Botox injections into the thyroarytenoid muscle are a predictable and effective treatment for SD, but typically result in transient symptoms of voice weakness and breathiness during the first 2-3 weeks after injection. Investigators hypothesize that voice weakness and breathiness after Botox treatment can be alleviated using amifampridine.

Primary Outcome

VHI-10 is a scale used to assess the severity of problematic symptoms associated with the voice. It is a series of 10 questions. Each questions is answered using numbers 0-4, with 0 meaning the patient never has a problem with that symptom; and, 4 meaning the patient always has a problem with that symptom.
