Has anyone heard of using these devices for aiding PWP who have bradykensia [freezing]? A very short article in the August issue of Popular Science Magazine, of all places, describes their use by doctors at the University of Rochester's Strong Memorial Hospital, and makes the statement that, "It's not often that a debilitating symptom affecting as many as 150,000 patients might be alleviated by a cheap, readily available fix."

I would like to try one but these laser pointers come in various colors and range from real cheap to real expensive. And the article does not describe exactly how it would be used to stop freezing. Does anyone know anyone at this hospital so you could make an inquiry?
