73-year old man with Parkinson's disease.
A sense-stimulating aid: Protac MyFit ball vest
Observed effect: "I use the vest throughout the day, when I play piano, write by hand and do practical things at home.
The vest gives me a feeling of greater inner peace during all of these activities, and also the feeling that I'm doing them very well. It gives me a sense of security, grounding, deeper and relaxed breathing and a straighter posture".
