In this instructional segment, David Brimacombe explains how post‑concussion syndrome (PCS) symptoms can become linked to perceived danger, such as climbing steps, creating a feedback loop where symptom provocation heightens stress, which in turn worsens symptoms. He proposes using mental visualization—imagining moving up and down the steps without experiencing symptoms—to signal to the brain that the activity is safe. This re‑training aims to break the stress‑symptom cycle, reduce symptom flare‑ups, and promote nervous‑system recovery.

And in that moment, they thought that there was an intense amount of danger in climbing those steps because those steps were causing your symptoms to flare, and those symptoms would create more stress, which would cause greater symptom provocation. So by actually visualizing a time in my, my mind where I could go up and down without having symptoms would tell my brain, wait a minute, maybe this is safe. Maybe this is okay.
