Abstract

In the area of dystonia treatment, we have continued to provide botulinum toxin injections to our patients while training physicians to perform these injections. We recently completed a study comparing electrophysiologic and ultrasound guidance for injections that shows that patients prefer the latter although the efficacy is similar (NCT02326818). Past studies from our group have shown that certain rehabilitation techniques, such as motor training and sensory training can be therapeutic. We have also been developing a new scale for severity of writers cramp to help in the analysis of clinical trials and are completing an analysis of its reliability. The botulinum toxin program will be continued under the leadership of Dr. Debra Ehrlich. Another protocol (in collaboration with the Parkinson Clinic) is ongoing for Deep Brain Stimulation (DBS) for focal hand dystonia (NCT0291110). We have completed and published a successful pilot study of non-invasive brain stimulation for functional movement disorders (NCT03263013). The technique inhibits the overactivity of the amygdala by stimulation of an area of the dorsolateral prefrontal cortex that connects to the amygdala. A double-blind controlled trial has begun to follow-up this exciting observation (NCT05155059) and is now under the leadership of Dr. Sophie Cho. We have also collaborated with the Parkinson clinic on a pilot therapeutic trial of medium-chain triglycerides in patients with Parkinson disease (NCT04584346).
