Summary

This study tests a small device that sends gentle electrical pulses to nerves in the ear to help children ages 11-18 with post-concussion syndrome or long COVID symptoms like pain, nausea, and balance problems. Participants must have had symptoms for at least 3 months. The goal is to see if this treatment improves daily functioning and reduces discomfort.
