I may still be a white belt on the mat, but when it comes to fixing bodies, I am most definitely a black belt...


With more than 25 years of experience in correcting structure and restoring posture, I know how to correctly identify and successfully treat most of the nagging, recurring injuries that affect martial artists, most specifically, BJJ practitioners.

Originally from New Jersey where I attended Rutgers University and earned a degree in Exercise Science and Physiology, I went on to get my Doctor of Chiropractic degree in 1994.  My practice focuses on the utilization of Advanced Biostructural Correction™ (ABC™), a highly specialized and effective hands-on assessment and progressive treatment that unlocks the subtle but potentially damaging twists in the body that can lead to an array of symptoms and syndromes involving the head, neck, back, arms, hands, legs, or feet.  

BJJ Injuries Explained


What Do All of the Positions in the Following Photos Have in Common?


All of these positions are causing forcible flexion onto one of the practitioner's head, neck and/or upper back.  This is an issue because this action has the potential to push (or pull) a spinal vertebra forward.

Why is that a problem?

Anyone who has studied basic anatomy knows muscles pull bones, they can’t push them, and your spine is no different.  You have muscles to pull your vertebrae in every direction except backward.  No muscle exists there to pull the bone(s) back when they shift forward, and this causes a loss of normal leverage.

So your spine has to counterbalance by pulling other vertebrae into compromising positions, causing the pain and stiffness you feel...

For every inch your spine leans forward off your center of gravity your back muscles have to leverage an additional 10 pounds. This forward shift can also stretch your spinal cord and its surrounding tissues leading to pinched nerves, arthritic decay and long term muscle strain.


Look at the picture above on the right....

  1. However it may have happened (rolling, accident, fall, impact, etc.), this practitioner has lost leverage due to a vertebra shifting forward (primary shift) - notice how his spine bends/folds here 

  2. Notice how far forward the center of his head is positioned in relation to the center of his body here

  3. Notice how his shoulders are rolled forward here

The result of this structural problem is that his body must compensate for the loss of leverage (secondary shifts) - which can eventually cause many seemingly unrelated chronic and recurring symptoms, such as...


My treatment method, Advanced Biostructural Correction™ (ABC™), restores proper leverage to body structure, which leaves you standing taller and straighter, taking fuller, deeper breaths, increases range of motion, corrects muscle imbalances, alleviates pain, and creates lasting stability.

"I have been a Jiu-Jitsu practitioner for the past 15 years.  During that time, I have collected many devastating injuries, but just recently, I started dealing with a career-ending one.  After a few long back-to-back sessions, I started having cramping issues with my hands.  At some point, they would actually seize up.  While not too painful, I was not able to do anything at all but try to physically open and close one hand with the other.  As someone who depends on his grips for his living, this was akin to an artist losing his sight.  I spoke with Dr. Freedman and he assured me he could help.  After just a few sessions I was not only "cured" but fought in my hardest contest to date and never once had an issue with grips during or after my match!  Dr. Freedman's knowledge of the human body, especially athletic bodies, is outstanding and I am happy to be a patient.  I know I am in good hands!"
