The reference database for Muscle Response Testing.
873 muscles. 528 muscle tests. 3,087 balancing factors. Three languages. Built by a practitioner who needed it and couldn’t find it.
Every MRT practitioner knows this moment.
You are in a session. Something doesn’t respond the way it should. You need a reference — fast. The textbooks don’t cover it. Your training notes are somewhere else. Your colleagues are busy.
The field of Muscle Response Testing has grown for over 60 years. Applied Kinesiology, Touch for Health, Applied Physiology, specialized kinesiology — hundreds of protocols, thousands of clinical connections, across dozens of traditions. Documented everywhere and nowhere.
This is what Knowlative was built for.
A reference built for clinical practice.
The Knowlative database is not a course. It is not a certification. It is the systematic reference that MRT practitioners have needed since Goodheart first documented applied kinesiology in 1964.
- Muscle protocols by function, region, and clinical indication
- Nutritional and metabolic connections for each muscle
- Neurological and autonomic patterns
- Technique cross-references across AK, Touch for Health, Applied Physiology, and related traditions
- Embedded reference videos for visual confirmation
- Every entry cross-linked — nothing sits in isolation
Built by Dr. Ludovico Feletto, MD.
I am an orthopedic surgeon and the founder of Knowlative. I built this database in 2018 because the reference I needed for my clinical practice didn’t exist.
After 20 years of practice, six international conferences, and over 200 practitioners trained, Knowlative is now the reference database for Muscle Response Testing — maintained by a clinician who uses it daily.
Courses and conference recordings
Beyond the database, Knowlative hosts the recordings of its international conferences and complete courses — including Biofeedback Essentials and Preventive Orthopedics. Three conferences are free: 2020 and 2021 with a free account, 2022 with the newsletter. Each course is available on its own page.
