Transcranial magnetic stimulation (TMS) is a widely used, noninvasive method for stimulating nervous tissue, yet its mechanisms of effect are poorly understood. Here we report new methods for studying the influence of TMS on single neurons in the brain of alert non-human primates. We designed a TMS coil that focuses its effect near the tip of a recording(More)
INTRODUCTION A shorter delay time from chronic pain diagnosis to spinal cord stimulation (SCS) implantation may make it more likely to achieve lasting therapeutic efficacy with SCS. The objective of this analysis was to determine the impact of pain-to-SCS time on patients' post-implant healthcare resource utilization (HCRU). METHODS A retrospective(More)
OBJECTIVE To investigate the role of advancing age on postoperative complications and revision surgery after fusion for scoliosis. METHODS A retrospective, cohort study was performed using the Thomson Reuters MarketScan database, examining patients with adult scoliosis who underwent spinal fusion from 2000 to 2009. Primary outcomes included infection,(More)
Essential tremor (ET) was the original indication for deep brain stimulation (DBS), with USA Food and Drug Administration approval since 1997. Despite the efficacy of DBS, it is associated with surgical complications that cause sub-optimal clinical outcomes. Given that ET is a progressive disease with increase in symptom severity with increasing age, this(More)
We introduce a novel platform for medical device training: hybrid physical-virtual simulators of medical devices, combining touchscreen-enabled virtual emulations of real devices with sensorized physical peripherals to enable tactile, hands-on interaction between the trainee, simulated device and standardized patients or mannequins. The system enables(More)
OBJECTIVE Spinal cord stimulation (SCS) has been proven effective for multiple chronic pain syndromes. Over the past 40 years of use, the complication rates of SCS have been well defined in the literature; however, the incidence of one of the most devastating complications, spinal cord injury (SCI), remains largely unknown. The goal of the study was to(More)
OBJECTIVE The most popular surgical method for deep brain stimulation (DBS) in Parkinson's disease (PD) is simultaneous bilateral DBS. However, some centers conduct a staged unilateral approach advocating that reduced continuous intraoperative time reduces postoperative complications, thus justifying the cost of a second operative session. To test these(More)
