Even after all this research and FDA approval there is still no protocol on how to use, the damage diagnosis that would indicate its' usage or anything useful that would help survivors recover. Why the fuck is stroke research being done if outcomes never are delivered that help survivors?

Paired vagus nerve stimulation for treatment of upper extremity impairment after stroke
Abstract
The
use of a paired vagus nerve stimulation (VNS) system for the treatment
of moderate-to-severe upper extremity motor deficits associated with
chronic ischemic stroke has recently been approved by the US Food and
Drug Administration. This treatment aims to increase the task-specific
neuroplasticity through the activation of cholinergic and noradrenergic
networks during rehabilitation therapy. A recent pivotal Phase III trial
showed that VNS paired with rehabilitation led to improvements in upper
extremity impairment and function in people with moderate-to-severe arm
weakness for an average of 3 years after ischemic stroke. The
between-group difference following 6 weeks of in-clinic therapy and
90 days of home exercise therapy was three points on the upper extremity
Fugl-Meyer score. A clinically meaningful response defined as a greater
than or equal to six-point improvement was seen in approximately half
of the people treated with VNS compared to approximately a quarter of
people treated with rehabilitation alone. Further post-marketing
research should aim to establish whether the treatment is also of use
for people with intracerebral hemorrhage, in people with more severe arm
weakness, and for other post-stroke impairments. In addition,
high-quality randomized studies of non-invasive VNS are required.
