Study Summary

This trial is studying whether a treatment called repetitive transcranial magnetic stimulation (rTMS) can help people with chronic post-concussion symptoms.

Who is the study for?

This trial is for adults aged 18-65 with persistent post-concussion symptoms like headaches and cognitive issues, diagnosed per ICD-10 criteria. Participants must have had a concussion within the last 5 years and can't change their current medications during the study. Those with TMS contraindications or certain medical conditions are excluded.Check my eligibility

What is being tested?

The trial tests if repetitive transcranial magnetic stimulation (rTMS), a drug-free neuromodulation therapy, can improve chronic symptoms after a concussion. It also examines how brain function changes relate to clinical improvements using functional near-infrared spectroscopy (fNIRS) as a response marker.See study design

What are the potential side effects?

While not explicitly stated in the provided information, common side effects of rTMS may include headache, scalp discomfort at the site of stimulation, tingling or spasms of facial muscles, lightheadedness, and rare risk of seizure.

Trial Design

Experimental Treatment

Placebo Group

Group I: Treatment groupExperimental Treatment1 Intervention

Patients will engage in a four-week treatment protocol (20 treatments). This was chosen as it is the midpoint between typical depression and migraine protocol durations. A standardized atlas brain with Montreal neurologic institute (MNI) coordinates will be used for navigation. The DLPFC will be located through MNI coordinates (-50, 30, 36). The intensity of the rTMS will be 100-120% of resting motor threshold amplitude, with a frequency of 10 Hz, 10 trains of 60 pulses/train (total of 600 pulses) and an inter-train interval of 45s.

Group II: Sham groupPlacebo Group1 Intervention

In the sham condition, a sham coil will be applied to the scalp after the resting motor threshold is determined. Patients will be able to hear the sound and feel the vibration of sham coil, but will not experience any effective stimulation. Previous sham studies have demonstrated efficacy of the blinding method.
