Deep brain stimulation (DBS) can be complicated by adverse events, which are generally classified as surgical-hardware or stimulation-related. Here we report the onset of a painful cervical dystonia probably triggered by the extension wire of a subthalamic nucleus (STN)-DBS device in a woman suffering from advanced Parkinson's disease (PD). Two months after implantation of the STN-DBS device, our patient developed a painful cervical dystonia, which was not responsive to neurostimulation or to medication. No sign of infections or fibrosis was detected. A patch test with the components of the device was performed, revealing no hypersensibility. The patient was referred back to surgery to reposition the pulse generator in the contralateral subclavian region. A deeper channeling of the wire extensions produced a complete remission of the painful dystonia.
