GPi DBS treatment in Postural instability in Parkinson's disease with 8 contact lead experience.

Deep brain stimulation (DBS) has been a widely accepted treatment modality for advanced Parkinson's disease (PD). Postural instability in PD have been a great challenge in the clinical practice.In the PD patients with postural instability, the selection of DBS targets is still challenging. GPi target for deep brain stimulation (DBS) in the treatment of postural instability is more preferred. In this article we want to share our experience with GPi target in PD. We present 5 patients who underwent to Gpi DBS for PD and we compare preoperative condition with 6th month follow up. we used a variety of different scales to measure the severity of the patient's symptoms, including the Unified Parkinson's Disease Rating Scale (UPDRS), the freezing of gait questionnaire (FOG-Q) and the gait and falls questionnaire (GF-Q).GPi DBS have positive effects to postural instability as well as freezing of gait and falling after PD.
