Pure Training Roll — Book I

Pure Training Roll — Book I: Foundations & Science is a 15-module certification curriculum by Leon Cherbukhovsky, First Edition 2026. Patients access it from the Course tab in Veridian Academy. Clinical authority stays with licensed clinicians. The curriculum is educational and non-diagnostic. The product does not diagnose.

​

Modules

Fifteen modules cover:

1. How the roll works
2. Foundations of human movement
3. Functional anatomy
4. Co-contraction and joint control
5. What the roll changes
6. Controlled instability and motor learning
7. Isometric exercise
8. Moving while stabilising
9. Self-generated perturbation
10. Reciprocal movement
11. Multiplanar movement
12. Progression and regression
13. Pain and stiffness
14. Programming and recovery
15. Safety and responsibility

Each module ends with a knowledge check and a competency objective. Knowledge checks are open-response and are deliberately not scored — they prepare the learner for the examination.

​

Book I Participant Competency Examination

Passing issues a printable Certificate of Completion naming Leon Cherbukhovsky as author.

​

Examination security

The answer key never reaches the browser. Design:

1. The key lives in a staff-only, RLS-protected table
2. Participants fetch the paper through a security-definer function that returns questions without the answer column
3. Submission is graded by a second security-definer function inside the database

A participant cannot read the key even by querying directly.

​

What it is not

• Not a clinical license or professional credential beyond the program’s own Certificate of Completion
• Not a diagnosis or treatment plan
• Not scored knowledge checks (those prepare for the exam only)
• Not a claim that the provisional 80/100 pass mark is clinician-finalized
