> ABSTRACT
>
> The centre median-parafascicular (CM-Pf) complex of the thalamusis
> considered to be a possible target for deep brain stimulation(DBS) in
> patients with movement disorders. In a prospectivestudy on the effect
> of CM-Pf DBS versus somatosensory thalamicDBS on chronic neuropathic
> pain, three of 12 patients had additionalmovement disorders. Bifocal
> quadripolar electrodes were implantedby computed tomography guided
> stereotactic surgery under local anaesthesia contralaterally to the
> side of the pain for teststimulation. Two of the three patients with
> movement disordershad permanent implantation of CM-Pf electrodes.
> During teststimulation of the left CM-Pf complex for several days, a
> 67year old woman received no benefit with respect to the
> neuropathicpain, but the choreoathetotic movements of her right foot
> ceased. As the pain syndrome was not improved, she decided not to
> havepermanent implantation. A 74 year old man with postzoster
> neuralgiaand allodynia enjoyed excellent relief from his pain with
> chronicCM-Pf DBS. In addition, improvement in the tremor at rest
> wasnoted. A 72 year old man had sustained reduction in his
> stumpdyskinesias. Further evaluation of the possible role of
> the"forgotten" central and medial thalamic nuclei in the treatmentof
> movement disorders may be warranted.
