Speech Therapy Found to be of NO Benefit for Spasmodic Dysphonia

A recent study was published that has found that speech therapy had minimal if any significant beneficial effect on spasmodic dysphonia (a spastic vocal disorder) in a study cohort of 31 patients.

The study was divided in 3 patient treatment groups:

- One-third received no further intervention after botox injection which is considered standard of care in the treatment of spasmodic dysphonia
- One-third received a standard 5-week course of voice therapy after botox injection
- One-third received a 5-week course of sham voice therapy after botox injection

All patients regardless of treatment group experienced improved voice quality in response to botox injection.

However, patients who received voice therapy after botox injection did not experience longer injection effect duration or significantly greater improvements in vocal quality than patients in botox only or botox plus sham therapy groups.

Dr. Chang performs botox injections for spasmodic dysphonia every Friday afternoon.
