tVNS During Motor Training in Older Adults

NCT06323954 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 32

No results posted yet for this study

Summary

The goal of this study is to learn about the effect of applying transcutaneous vagus nerve stimulation (tVNS) during motor training on motor learning in older adults. The main question it aims to answer is whether applying tVNS after successful motor trials (post-success tVNS) will facilitate the rate of motor learning. Participants will be randomly assigned to tVNS or sham group and receive tVNS or sham, respectively, at the outer ear during finger control training sessions. Finger control performance will be tested before and after the training sessions without outer ear stimulation.
