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.

Who should consider this trial

Good fit: Ideal candidates for this registry are patients with upper limb deficits due to ischemic stroke who are considering the Vivistim System implant.

Not a fit: Patients who are not eligible for surgery will not benefit from this registry.

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 performed: 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.
