We do have many customers reporting that using TouchPoints on the calm, anger, or performance settings may reduce the incidence of tremors associated with Parkinson's. Also, many customers report that using TouchPoints helps reduce the anger/agitation, and anxiety associated with these conditions and the "rebound" effect of medication.
There are two types of tremors, resting tremors and action tremors. TouchPoints seems to make action tremors better. Since Essential tremors and cerebellar tremors and action type tremors, we believe that Touchpoints technology works on the same brain circuity which is why they would likely result in improved control and tremor severity.
Currently, there are universities interested in pursuing research given these findings, but we as a company have not yet researched this. TouchPoints are shown to reduce the overall stress response and since TouchPoints are a general wellness device, we are still learning of so many potential applications to improve people's lives!
