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.”

2026, The Year of the Horse!

Original post by: Ann Montgomery-The Mindful Rider

@annmontgomery_themindfulrider 

“A number of years ago I had an interesting lesson with a student. The rider was struggling with getting a constant contact with her horse. After watch both of them move around the arena for a while and seeing the mare, chomp, and fiddle with her tongue and bit I asked the rider “where is your tongue sitting in your mouth? To this the rider stopped the horse and said ” how the hell did you know that” so it turns out that this rider has a gap in-between one of her upper molars and she has a habit of twisting her tongue to place the tongue in the gap.
When I asked her to place her tongue softly onto the top of her mouth the horse became quite in its contact and as the lesson went on the horse began to move freer in the shoulders, the rider’s tonal quality of her arms into her hand and fingers became a soft tone.
 
So why is this so, I asked myself, and did some research.
 
Why would the riders tongue affect the horses tongue so much?
 
Well from what I have researched the hyoid bone is part of the tongue movement apparatuses as the omohyoid muscle origin site at the superior border of the scapula and can vary in location and in size, and at times the muscle also originates from the superior transverse scapular ligament. The attachment of the central tendon can be only to the clavicle or to the clavicle and the first rib.
 
Wow I thought so when her tongue curls up a whole tension goes from her tongue down to her shoulder which must create a tension down her whole arm to her hand. This in turn puts a tension onto the rein and bit which travels onto the horse’s tongue, so guess what this also affects the horses hyoid bone and his omohyoid muscle into the shoulder causing the tight steps and fussy mouth. It’s a circle of tension.”

“This single leg stance activity is very helpful in assessing sensory and motor integration between the left and right hemispheres of the cerebrum and the cerebellum, as well as between the upper and lower hemispheres of the diaphragm or mid thorax.

If functional disconnection occurs when standing on the left leg, as above, disconnection of the right brain, or right brain deficiencies for the left lower extremity is probably a greater issue than left brain deficiency.

If functional disconnection occurs only when standing on the right leg, disconnection of the right brain, again, or right brain deficiencies for the left upper extremity is more than likely a greater issue than left brain deficiency.

Right brain deficiencies are the most common type of deficiency seen in children with 'brain imbalance.' Melillo R. Disconnected Kids. 2015”

Early Registration Ends Friday! Start your New Year with #prination

“This course has really helped me bring my work with PRI to the next level. Integrating the primary coursework and helping me understand how they relate to each other.”
 
“Dan knocked it out of the park. Funny. Emphasized key points with repetition, slower speech and volume. So clear and natural. It was easy for me to know what was really important and to take in. I was completely engaged the whole class even though I was streaming from Alaska which meant I was getting up at 4am to attend.”
 
“I have more validation that many orthopedic conditions have a neurologic underpinning, and that my role would be to foster a new sensory experience that is salient to the patient and reproducible under their own volition”
 
“This course helped me understand that the L calcaneus ‘impingement’ or sense is largely neurological, and the PRI non-manual techniques need to be taught with a minor on the muscles engaged and a major on the ‘sense’ of the body in a new position. I plan to use this course to emphasize my ability to teach and perform PRI-non manual techniques utilizing Pilates equipment.”
 
“The Impingement and Instability course is THE intersection between neurology and biomechanics. Dan is an incredibly adept in tying together the concepts from the Postural Restoration Institute’s primary courses and elevating the student to a greater understanding of the principles underpinning the integration between body position and body sense. I will absolutely be seeking out additional opportunities to hear Dan speak about applying PRI to my daily clinical practice.”

“Fantastic course. My favorite so far.”
