The Vivistim implanted vagus nerve stimulator device from MicroTransponder could help patients recover motor control more quickly after a stroke.
Typical stroke rehabilitation includes physical therapy to repeatedly move the affected limb, stimulating neural plasticity and reorganizing the circuitry in the brain.
To enhance the treatment, a team from UT Dallas developed the Vivistim, which can be implanted in the neck to stimulate the vagus nerve in time with the movements of the affected limb. In tests, volunteers outfitted with the Vivistim device during therapy showed twice the movement improvement over patients without the device.
