ABSTRACT
Background: Tremor in Parkinson's disease (PD) is commonly seen in the upper extremities and can involve the lower extremities and mouth. We present a case of a patient with idiopathic PD who presented with abdominal tremor. Case Report: A 40-year-old man with a 2-year history of subjective weakness and stiffness in the right arm and leg, followed by emergence of a right hand tremor, subsequently developed abdominal tremor. Patient experienced marked improvement of both abdominal and hand tremor and mobility of the right limbs with levodopa. Discussion: Our case report serves as the second only published report of abdominal tremor in an idiopathic PD patient. Highlights: Tremor in Parkinson's disease (PD) commonly affects the upper and lower extremities and mouth. We describe a 40-year-old man with PD who developed abdominal tremor which was brought under control with levodopa. This case is one of only two published reports of abdominal tremor in PD.

Few centers have routinely implemented robotic stereotactic systems for deep brain stimulator (DBS) placement. The present study compares clinical outcomes associated with robotic-assisted subthalamic nucleus (STN)-targeted DBS surgery in patients with Parkinson's disease (PD) to those of the traditional frame-based method. A retrospective chart review was performed (February 2013-June 2017). Thirty-three patients were implanted using the Cosman-Roberts-Wells (CRW) frame and 27 patients were implanted using the ROSA robot. Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) or UPDRS part III motor scores and levodopa equivalent daily doses (LEDD) were examined preoperatively and at 6, 12, and 24 months of follow-up. Operative times and complication rates were recorded. For the frame-based group, the reduction in the mean MDS-UPDRS part III motor score compared to baseline was 27% both at 6 and 12 months, and 36.7% at 24 months. For the robotic-assisted group, the reduction in the mean motor score from baseline was 17.6% at 6 months, 19% at 12 months and 21.4% at 24 months. The mean LEDD for the frame-based group decreased by 48.7% at 6 months, 56.7% at 12 months, and 29.7% at 24 months. For the robotic-assisted group, the mean LEDD decreased by 42% at 6 months, 45% at 12 months and 50% at 24 months. There were no significant differences in the mean motor scores and the LEDD reduction between the two groups. Operative times tended to be longer for robotic-assisted DBS surgery. Clinical outcomes associated with robotic-assisted surgery are comparable to those with frame-based surgery.

BACKGROUND: Electrode implantation for deep brain stimulation (DBS) can be performed in numerous ways, but the current "gold standard" is the use of frame-based systems for accuracy. Robotic stereotactic procedures, however, have gained increased interest because of their ease of use and reliability, but there could be concern about their safety in the United States as the result of recent lawsuits (e.g., the da Vinci Surgical System). We report the first DBS implantation performed using a robot (ROSA robotic device) approved by Food and Drug Administration for use in North America. CASE DESCRIPTION: A 56-year-old, right-handed woman with a 12-year history of Parkinson disease is described. She was offered bilateral subthalamic nucleus DBS placement to address motor fluctuations and dyskinesias. DBS electrode implantation was implemented successfully with ROSA robotic stereotactic assistance. Using preoperative magnetic resonance imaging scan acquisitions, we targeted the patient's subthalamic nucleus bilaterally. Bone fiducials were placed and intraoperative computed tomography (CT) imaging was obtained. The magnetic resonance imaging and CT were fused, and the patient was registered to the ROSA software. Trajectories were obtained and a microdrive device was fixed to the robotic arm to advance the electrode to the correct location. Electrodes were then placed bilaterally. Intraoperative CT showed good placement with no complications encountered. CONCLUSIONS: The advantages of robotic assistance in stereotactic procedures are as follows: 1) improved accuracy, 2) "arc-less" approach, and 3) minor adjustments can be made in multiple planes to the entry point without adjustment of a frame. The case demonstrates robotic stereotactic assistance viability as an alternative to traditional frame-based or frameless systems in U.S. hospitals.
