Conventional VIM-DBS versus the alternative approach, PSA-DBS.. A: Deep brain stimulation of VIM as the conventional intervention of choice was not helpful in reducing tremor. B: Deep brain stimulation of PSA as the alternative strategy resulted in satisfactory control of the tremor. #Trajectories of the leads demonstrated in this figure are putative and do not represent the actual tracts in the surgery.
