"It's not a mechanical problem. It's a biological debt."

Why do some patients plateau despite perfect manual technique? In this episode, Jamie Johnston dives into the structural and neurological changes that trauma leaves in the body—long after the distressing event has passed.

We move past the philosophy of trauma-informed care and get into the hard science: how childhood trauma alters gene expression (Epigenetics), why adulthood stress creates a "physiological overdraft" (Allostatic Load), and why your geriatric patients lack the "biological bounce-back" they once had. This isn't just about being "nice" to your patients; it’s about understanding the specific biological mechanisms that drive persistent pain.

Inside this episode, we discuss:

• Epigenetics & The NR3C1 Gene: How childhood trauma can "switch off" the body’s ability to build cortisol receptors, leaving the stress response running indefinitely.
• The Allostatic Load Bank Account: Why complex adult patients are often living in a state of "overdraft" where every minor injury tips the system into widespread pain.
• The Geriatric Nervous System: Why aging naturally raises baseline cortisol and damages the hippocampus, making calm clinical environments a biological necessity.
• Red Flags for Referral: Recognizing when a child or adult needs psychological support beyond the manual therapy scope.
• The Power of Presence: Practical ways to restore the sense of control that trauma takes away through choice, routine, and predictability.

Go Deeper: This episode is a preview of the frameworks found in Jamie’s focused mini-course, "From Fear to Functional." Designed specifically for manual therapists, this course helps you turn these neurobiological insights into concrete clinical decisions.
