About Us

Education & Services For Improved Pathways of Physical Medicine

The Postural Restoration Institute® (PRI) was established in 2000 to explore and explain the science of postural adaptations, asymmetrical patterns and the influence of polyarticular chains of muscles. 

The Postural Restoration Institute® (PRI) is a continuing education institute that was established in 2000 to explore and explain the science of postural adaptations, asymmetrical patterns and the influence of polyarticular chains of muscles. We offer 12 post-graduate level courses, in addition to an annual PRI Interdisciplinary Studies Summit, and we welcome any licensed healthcare or certified fitness professional to attend our courses. Professional credentialing opportunities (PRC, PRT and PRP Japan) are available to qualified professionals.

The human body is not symmetrical. The neurological, circulatory, muscular and visual systems (just to name a few) are not the same on the left side of the body as they are on the right. The Postural Restoration Institute® was established in 2000, to help healthcare and fitness professionals recognize this underlying asymmetry of these systems in our body, and the postural imbalances and patterns associated with dominant, unconscious or conscious overuse, of one side of the body; our right side.

PRI credentialed providers offer a unique approach to physical medicine called Postural Restoration®. This approach addresses underlying biomechanics which can often lead to symptoms of pain and dysfunction. All mechanical influences on the body that restrict movement and contribute to improper joint and muscle position are considered, examined, and assessed. Non-manual and manual techniques are utilized to restore proper alignment of the body while proper respiratory dynamics are considered. Management encompasses prevention and lifetime integration for long-term successful outcomes.

PRI credentialed providers have completed multiple advanced PRI courses, demonstrated a thorough understanding of the primary concepts through completion of an in-depth application process, and successfully participated in both practical and analytical testing onsite in Lincoln, Nebraska.

We do not see patients here at the Postural Restoration Institute, however we can help you Find a Provider near you (see map below)!

Postural Restoration Certified (PRC) professionals are Physical Therapists, Physical Therapist Assistants, Chiropractors and Occupational Therapists who have completed the Postural Restoration Certified credentialing program. 

Postural Restoration Trained (PRT) professionals are Athletic Trainers and Strength & Conditioning Coaches who have completed the Postural Restoration Trained credentialing program. 

Postural Restoration Provider (PRP) professionals are healthcare and movement professionals in Japan, who have completed the Postural Restoration Provider credentialing program, offered through PRI Japan. The professional backgrounds of these healthcare and movement professionals are notably different than the individuals going through the available PRC and PRT Credentialing pathways here in the U.S. and the Postural Restoration Provider (PRP) Japan Credential is available to various healthcare and fitness professionals in Japan, who are appropriately applying the science of Postural Restoration®

A Postural Restoration Center is a place of business where at least one individual is PRI Credentialed (PRC or PRT) and all other individuals on staff who are eligible for credentialing (which includes PTs, OTs, PTAs, Chiropractors, Athletic Trainers, Athletic Therapists, Strength & Conditioning Coaches with CSCS or SCCC credential, CSPS, and Exercise Physiologists), have completed two or more PRI-sponsored courses.

*To ensure that credentialed providers are keeping up with the progressive science and growth of Postural Restoration®, those listed on this page have taken a course or completed credentialing within the past 5 years. You can view the PRI® courses that each provider has completed by clicking on their individual page. 

**If you are unable to find a PRI® credentialed provider in your area, please contact us to see if there is anyone who has taken PRI® courses near you. 

What Patients are Saying

Erin Rajca
Erin RajcaPostural Restoration Certified
"I trust Dr. Erin implicitly and I recommend her to everyone I know for physical therapy! She is so thoughtful and thorough and is amazing at identifying the postural restoration techniques to make life changing adjustments. She listens to you and explains how shifts in your body mechanics ease pains and sets you up for success going forward. I am a busy professional, and I was getting frustrated by the constant aches and pains caused by my physically demanding job, Dr. Erin has helped me through many events, relieving my discomfort and empowering me to a healthier, more sustainable version of myself."

Alex Maag
Alex MaagPostural Restoration Certified
“As my daughter, Jenna, and I write this, we cannot speak highly enough about how Alex provided excellent care for Jenna. Jenna had Pectus Excavatum surgery at Cincinnati Children's Hospital in April 2023. We live 2 1/2 hours from Cincinnati and Jenna needed PT before and after surgery. Alex was recommended to us and honestly, we would have been lost without him. Having him in our area is a lifesaver. I sent his credentials to Cincinnati Children's PT and they said this would be great fit for Jenna. He focused on her posture, breathing, lung expansion and strengthening as well as adapting to her needs. Jenna is a swimmer on multiple swim teams as well as a high school soccer player. With Alex's help, she was able to return to competition in the pool and on the soccer field in a shorter amount of time.”

Torin Berge
Torin BergePostural Restoration Certified
“I came to the Hruska Clinic last November diagnosed with extreme anxiety and difficulty breathing. Torin became my PT, and he demonstrated such warm compassion and patience for my condition. I was having difficulty breathing deeply, and he started me slowly on a program that over two and half months helped me restore my ability to breathe deeply. I felt safe and confident in the exercises he demonstrated and gave me to do at home. I am so appreciative of his knowledge and care. Definitely five-star service.“
Lori Thomsen
Lori ThomsenPostural Restoration Certified
“The best way I can describe what Lori and the Hruska Clinic did for me is that they gave me my life back. I came to them with pain, migraines and a list of issues that to me, would never get better. Over the course of less than a year, Lori gave me a solution to every single issue and best of all, my pain and migraines went away entirely. I was able to get strong enough to learn how to downhill ski and start running again! Best of all, I know I have people on my team and strategies in my pocket when I need them again in the future. Thank you, Lori!”
Jason Masek
Jason MasekPostural Restoration Certified
“Jason is great. He helped me reach nearly pain-free status very quickly, after a different provider told me it would take a long time. Highly recommend.”
Paige McNerthney
Paige McNerthneyPostural Restoration Certified
“Paige has been the first physical therapist that I've had to actually connect the structural pain I was feeling to my chronic illness (POTS). Being seen as a whole person rather than just distinct aches and illnesses has been so instrumental in helping me work towards long-term wellness versus just quick fixes. I have gained so much insight into how my body is working through her extremely knowledgeable care. Her joyful personality and love for her work shines through in every appointment! I have loved working with her and am excited to continue.”

“What an exciting opportunity to travel to Munich Germany for the latest offering of the Human Evolution course! I felt so honored by the folks @lindebergs.health Academy with their gracious hospitality, amazing facility and yummy German treats.
 
We had a great group of attendees from not only Germany, but also Denmark, Italy, and China, as well as Michigan. It’s hard to imagine digesting the content of any PRI course in another language and this group really seemed to connect to the concepts presented. In fact, we had intellectually enriching discussions about the concepts of crawling, sensory processing, tonic neck integration, clockwise and counterclockwise sense and motion, and the sequential development of the glutes, to name a few.
 
Being that far from home, my partner and I had to stay to explore a bit. The trip was enriched with a delightful hike to the base of the Austrian Alps in Innsbruck. Though the descent proved to test my eccentric fitness… (turns out I have none). I left Austria with an amazing case of the DOMS (delayed onset muscle soreness), which in direct German translation means “muscle cats.” Whew… my cats were mad!
 
On to Bolzano, Italy where we enjoyed some shopping and delicious Italian fare. After a gondola ride to the base of the elusive Dolomites due to the clouds, for another hike, we had to go to the South Tyrol Museum of Archeology to see “Ötzi, The Ice Man”. The museum showcased research results of his physiology, gut, tools, and DNA for education. It was not at all surprising to see that his x-rays revealed more compression in his right hip than his left hip, VERY wide dental arches, and a more compressed right apical rib cage than his left. The photo depicts an approximation of what he might have looked like. You gotta love science!
 
A BIG THANK YOU to my gracious hosts Daniel Müller, Eckhart Acker, Sonja Voracek, and Regina Frank for taking such good care of me and for hosting a yet another PRI course. Also thanks to PRC’s Nadja Himmelseher and Tracey Blain for your valuable contributions to the conversations. It will be a trip we will remember forever.”

How does functional cortical dominance position us for movement?

If we are unable to sense or transition through midline (neutrality) at the pelvis, thorax, and cervical spine, our freedom to move through both hemispheres is lost.

I had such a great time in Lincoln October 24th and 25th. We had a fantastic crew in person to help demonstrate manual and non-manual techniques in order repattern rib cages and pressure flow. There was a very attentive audience from around the world online with stellar questions to facilitate the flow of the class and stimulate discussion about rib cage and pressure management. Canada, Germany, Taiwan, and states from around the country were represented online.

Some PRI celebrities were online with us as well! @untappedlouisville in Louisville, Kentucky and Jennifer Bullock outside of Telluride, Colorado. We were fortunate to have them there to drop some of their PRI knowledge and experience!

Laura and Emily were a superstar mother/daughter PRI duo that were such a joy to have in class. Laura was a fantastic primary demonstrator for our manual techniques and was a classic example of a Superior T4 syndrome individual. I am excited to be at the beginning of Emily’s PRI journey!

We were lucky to be graced with Joshua’s soothing Texas voice, as well as his amazing PEC thorax. It was fun to see my friend Lauren and her big smile throughout the weekend, hopefully this complimented Myokin nicely for you, Lauren!

Kyle was a joy to have in class, not only to talk bikes, but to discuss how this class has evolved and improved from when he took it 10+ years ago. It was good to hear from him what he remembered from 10+ years ago and how information on patterns, pressure, and perspective changes over time.

At the end of the class, I found out that I will be able to hang out with Samuel again next month in St. Louis. Looking forward to it, Sam! I am excited to hear how he takes his PRI knowledge back to the Reds. World Series 2026 for Cincinnati!

What a joy it was to be in Lincoln this last week. Thank you to everyone online and in person for being such a fun audience. I am very grateful I get an opportunity to talk about something I am passionate about for two days. My hope is that this will assist individuals from multiple disciplines around the world to understand the importance of a rib cage and air pressure biomorphology.

Traveling to Lincoln to teach from the heart of PRI is a fulfilling trip, I even caught a Nebraska volleyball win in person. The weekend flew by and this was also a reflection of how engaged and attentive the attendees both in person and online were during Myokinematic Restoration. We dove right into exploring the relationships between pelvic positioning, femoral orientation, and compensatory strategies upright humans exhibit during forward locomotor movement often referred to as gait. During lab demonstration, we were able to assess if the L AIC pattern was present and then further testing with the EXT drop test, the capsular integrity of the anterior hip capsule. We ended the first day with repositioning techniques to help inhibit the L AIC pattern. As an instructor, it was rewarding to hear attendees begin connecting the dots between the asymmetrical human position and how the techniques can be so powerful to change position on a neurological level. Reports of “feeling lighter” or “more grounded” were reported several times during lab.
 
The second day we explored the Hruska Adduction lift test and its respective grading scale. We used this assessment to determine the ability for one to be able to lateralize on the left and right side as well as shift to the opposite side correctly. This test requires frontal plane integration without the over use of sagittal plane muscles acting in the transverse plane. Such an important test when treating patients and prescribing appropriate techniques. The lab in the afternoon gave us plenty of time to work through several techniques that were reflective of different grades of the Hruska Adduction lift test.
 
I am continually grateful for the opportunity to share the PRI science. Thank you to the course attendees both local and virtual for the passion and questions on your learning journey.
