1. "Outcomes of Botulinum Toxin Treatment for Patients with Spasmodic Dysphonia."
Botulinum Toxin injections remain one of the leading treatments in the fight against Spasmodic Dysphonia (SD). But, what is the actual effect SD has on the quality of life? Michael S. Benninger, MD; Gelendon Gardner, MD; and Cynthia Grywalski, CCP-SLP took a closer look at this question by using a system called Voice Handicap Index (VHI) to measure the difference in the quality of life of 30 SD patients before and after Botulinum Toxin injections. The VHI uses a five point scale survey that measures the physical, functional, and emotional impact of SD. The study concluded that 22 of the 30 patients who completed the survey, post treatment, showed substantial improvement in their quality of life.

2. "Research Priorities in Spasmodic Dysphonia." In 2008, a diverse group of scientists and clinicians were assembled to analyze current Spasmodic Dyspohonia (SD) information and to decide on the top research priorities regarding the condition. (Backgrounds of the medical group gathered included: neurology, speech pathology, genetics, neuroscience, and otolaryngology.) The group hoped to gain a better understanding of the causes of SD, its diagnosis, as well as ways to improve available treatments. Ultimately, the group aimed to greatly improve the care of SD patients through speech pathology, neurology, and otolaryngology. The identification of risk factors of the disorder was deemed the top priority of research involving SD.
