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

Abstract

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.
