Research and Innovation Studies
Center for Neurologic Restoration
For more than 10 years, Swedish Neuroscience Institute has been at the forefront of innovation in treating chronic neurologic disease. Research projects and publications related to the Center for Neurologic Restoration include:
A Continued Access Study to Evaluate the Effectiveness and Safety of Exablate Transcranial MRgFUS Thalamotomy Treatment of Medication Refractory Essential Tremor Subjects
Goal: To evaluate the ongoing safety and efficacy of treatment using the ExAblate Transcranial System in medication-refractory tremor in patients with essential tremor.
EMG and Inertial Measurements of Essential Tremor
Goal: To obtain inertial measurements from post-operative ET patients with the device off and on at two levels of stimulator. This will allow the creation of an accurate pre- and post-operative assessment tool for tremor using a wearable device so we can better identify the most likely patients to respond to DBS treatment.
DBS Surgery Using a Mobile Intraoperative CT Scan
Goal: To assess the accuracy of the Airo (Brain Lab) intra-operative CT compared that of a fixed CT (SIEMENS) for patients undergoing DBS procedures.
RNS System Post-approval Study in Epilepsy
Goal: To follow patients prospectively over five years in the real-world environment to gather data on the long-term safety and effectiveness of the RNS System at qualified CECs by qualified neurologists, epileptologists and neurosurgeons trained on the RNS System.
A Global Registry to Evaluate Long-Term Effectiveness of Neurostimulation Therapy for Pain
Goal: To compile characteristics of real-world clinical outcomes, economic value and technical performance for Boston Scientific commercially approved neurostimulation systems for pain in routine clinical practice, when used according to the applicable directions for use.
Tissue Procurement and Repository for Future Neuroscience Studies
Goal: Tissue Procurement and Repository for Future Neuroscience Studies
A Pivotal Study to Evaluate the Effectiveness and Safety of ExAblate Transcranial MRgFUS Thalamotomy Treatment of Medication Refractory Essential Tremor Subjects
Goal: To test the safety and initial efficacy of treatment using the ExAblate Transcranial System against a sham control in medication-refractory tremor in patients with essential tremor.
This trial is no longer enrolling patients.
A Feasibility Study to Evaluate Safety and Initial Effectiveness of Exablate Transcranial MR-Guided Focused Ultrasound for Unilateral Thalamotomy in the treatment of Medication-Refractory Tremor Dominant Idiopathic Parkinson's Disease.
Goal: To test the safety and initial efficacy of treatment using the ExAblate Transcranial System against a sham control in medication-refractory tremor in patients with tremor dominant Parkinson’s disease.
This trial is no longer enrolling patients.
