What this trial studies
The Vivistim Registry for Paired VNS Therapy (GRASP) aims to collect real-world data on patients with arm and hand deficits following a stroke who are considering treatment with the Vivistim System. This observational registry will gather information before and after the implantation of the device, tracking patient outcomes over time. Data will be collected at multiple intervals, including baseline, 3, 6, and 12 months post-implant, and annually for up to three years. Patients who opt not to proceed with the implant can still participate as a comparison group, allowing for a comprehensive understanding of the device's impact.
Why it matters
Potential benefit: If successful, this registry could provide valuable insights into the effectiveness of the Vivistim System in improving upper limb function for stroke patients.
How similar studies have gone: While this registry approach is not novel, it builds on existing methodologies to gather real-world data on medical devices, which have shown success in other contexts.
