Bilateral deep brain stimulation of the globus pallidus pars interna (GPi) is the favored neuromodulation procedure in cases of cervical dystonia. The authors report on a case of unilateral GPi implantation that resulted in sustained benefit with marked improvement in pain and dystonia.
Abbreviations used in this paper: BTX = botulinum toxin; CD = cervical dystonia; DBS = deep brain stimulation; GPi = globus pallidus internus; SCM = sternocleidomastoid; TWSTRS = Toronto Western Spasmodic Torticollis Rating Scale.
