The terms behind the books

Health and chronic symptoms

These terms run through Unlocking True Relief, The Root Cause of Your Symptoms, Uncovered, and Gut Health Breakthrough. Everything here is general education, and none of it replaces care from your own clinician.

Fascia

The connective tissue web that wraps every muscle, nerve, blood vessel and organ in the body. It's continuous, which is why tension in one area can show up as pain somewhere else entirely.

Fascial counterstrain

A hands-on manual therapy. The practitioner locates a tender point, positions the body so the irritated tissue shortens and unloads, and holds it while the reflex spasm releases. Protocols exist for arteries, veins, nerves, lymphatics, ligaments and organs, so it reaches tissue that most manual therapy leaves alone. Covered in depth in Unlocking True Relief: Fascial Counterstrain.

Tender point

A small, precisely located spot of tissue that hurts under light pressure. In counterstrain it works as a map reference, telling the practitioner which structure is guarding.

Reflex spasm (muscle guarding)

An involuntary protective contraction the nervous system holds after an injury. It often outlasts the injury itself by years, which is one reason pain can persist long after imaging comes back clean.

Visceral counterstrain

Counterstrain applied to the connective tissue surrounding organs. Used for symptoms that don't follow a musculoskeletal pattern, such as reflux, pelvic pain, or abdominal pain without a clear structural explanation.

Lymphatic counterstrain

Counterstrain applied to lymphatic structures, aimed at swelling, congestion and post-surgical fluid retention.

Root cause

The upstream driver producing a symptom, as distinct from the symptom being managed. Root-cause work looks for what’s causing a symptom before trying to quiet it. See The Root Cause of Your Symptoms, Uncovered.

Intracellular micronutrient testing

A blood test that measures nutrient levels inside white blood cells rather than in serum. Serum levels can read normal while cellular stores are depleted, so the two tests can disagree.

Gut microbiome

The community of bacteria, fungi and viruses living in the digestive tract. It influences digestion, immune function and inflammation. See Gut Health Breakthrough.

Dysbiosis

An imbalance in the gut microbiome, where the mix of organisms shifts away from the pattern associated with normal function.

Intestinal permeability (leaky gut)

A state in which the gut lining allows particles into the bloodstream that would normally stay in the digestive tract.

Elimination protocol

A structured period of removing suspected trigger foods, then reintroducing them one at a time to see which ones actually produce symptoms.

Learning and education

These terms run through Personalized Learning Made Easy, Teaching and Education Without Burnout, and Mind-Blowing Connections For Kids.

Mastery-based learning

A model where a student moves forward once they've shown they know the material, rather than when the calendar says the unit is over. Gaps get filled before they compound. See Personalized Learning Made Easy.

Personalized learning

Instruction shaped to an individual student's current level, pace and interests, instead of a single pace set for a whole room.

Adaptive assessment

A test that adjusts difficulty in real time based on how the student is answering, so it finds the edge of what they know in fewer questions.

Learning gap

A specific skill a student missed that later material quietly depends on. Gaps build on each other, so a strong student can hit a wall 2 years after the gap first opened.

Grade-level pacing

The default model where a class moves at one speed regardless of individual readiness. It's built for scheduling and staffing, and it works well for the students sitting near the middle.

Teacher burnout

Chronic exhaustion produced by workload, administrative load and emotional demand. See Teaching and Education Without Burnout.

Leadership, career and identity

These terms run through The Leadership Playbook, Revisited, From Misunderstood HSP to Undeniable Changemaker, and Don't Just Survive, Thrive and Defy Limits.

Highly sensitive person (HSP)

A trait carried by roughly 20% of people, where the brain processes sensory and emotional input more deeply and notices subtlety others miss. Keryn's term for this group is OPALS, because the trait shows up as capability rather than fragility. See From Misunderstood HSP to Undeniable Changemaker.

OPALS

Overachieving, Perceptive, Altruistic, Leaders and Strategists. Keryn’s term for highly sensitive people, built from 5 traits that tend to show up together. OPALS deliver more than what’s asked, without needing credit. They notice small shifts before they can explain why. Serving the greater good motivates them more than praise. They take ownership when it counts, with or without the title. And they think long-term instead of chasing quick wins. See From Misunderstood HSP to Undeniable Changemaker.

Introversion

A preference for recharging alone. It's a separate thing from shyness, which is fear of social judgment. Plenty of introverts are highly social and very comfortable in front of a room.

Resilience

Building habits and systems that help you handle chaos, instead of just pushing through it. Pushing through only lasts so long. See Don't Just Survive, Thrive and Defy Limits.

The AI-era leadership habit

Handing routine work to AI by default, then using the time you get back for judgment, relationships and strategy. You can learn it at any skill level. See The Leadership Playbook, Revisited.

The first-week test

A simple check for any new tool or process: if it costs more hours than it saves in the first week, it’s not worth adding.
