What this trial studies

This study evaluates the effectiveness of Auricular Percutaneous Electrical Nerve Field Stimulation (PENFS) in children suffering from Post-Concussion Syndrome and post-COVID-19 symptoms. Participants will receive either an active or a nonactive Neurostim device, which is applied to the outer ear through tiny needles. The study involves neurological and cardiological assessments, and participants may be involved for up to 12 weeks depending on their group assignment. The aim is to determine if this treatment can alleviate symptoms and improve functioning in affected children.

Who should consider this trial

Good fit: Ideal candidates are children aged 11-18 with a clinical diagnosis of Post-Concussion Syndrome or post-COVID symptoms lasting more than 3 months.

Not a fit: Patients with significant developmental delays, seizure disorders, or those with implanted electrical devices will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide significant relief from pain and improve quality of life for children suffering from post-concussion and post-COVID symptoms.

How similar studies have performed: While the specific application of PENFS in this context is novel, similar approaches using electrical stimulation for pain relief have shown promise in other studies.
