Optimization of multi-pad surface electrode: Selective stimulation of wrist

We developed a method for automatic detection of the optimal contact within a multi-pad surface electrode that could be used for wrist tremor reduction in individuals with Parkinson´s Disease or Essential Tremor. This method is based on custom designed program that determines the optimal contact position, i.e. the position on the skin that is closest to the flexor/extensor muscle motor point. The method also takes into account patients´ comfort, as the contacts that produce painful contractions or stimulate sensory pathways are eliminated from the selection process.
