Reversing the polarity of bipolar stimulation in deep brain stimulation for essential tremor : a theoretical explanation for a useful clinical intervention
(2014-01-02)
The quadripolar electrodes used for deep brain stimulation are designed to give flexibility in contact configuration, optimize therapeutic effect, and minimize side-effects. A patient with essential tremor did not tolerate ...
