For nearly 70 years, Paul Bunyan and Babe, the Blue Ox have enjoyed fame of massive proportions, even being named by Eastman Kodak as one of the most photographed icons in the nation. But this year, Paul and Babe will have to get used to the dark — the Bemidji spotlight now shines on a new set of hometown heroes: the men’s and women’s Olympic curling teams.

For the athletes and for the entire Bemidji community, the chance to represent the U.S. in the Olympics was a dream come true. Behind the scenes, though, for two members of the women’s team, this dream — so close to becoming a reality — was slipping away.

Just weeks before they were to fly out to Torino, Jamie Johnson and Maureen Brunt were worried, to say the least. During what should have been key training and preparation time, the women found themselves sitting practice out, nursing painful injuries rather than curling.

Jamie’s pulled hamstring and Maureen’s IT band injury (which caused the muscles of her hip, knee and ultimately her entire left leg to be painful and tight) could not have happened at a worse time. “At practice I was already at the point where I couldn’t curl,” Maureen remembers. “I was so nervous that the injury would be a huge setback in Torino.” Jamie, too, was affected “not only physically, but mentally as well.”

Determined to get back on the ice fast, the women turned to MeritCare Bemidji physical therapists Megan Bollinger and Paula Vigen for help. Vigen had worked with Maureen before, but recognizing the need for immediate results, she consulted Bollinger about a new revolutionary technique called postural restoration. “This technique is designed to improve movement, posture and breathing,” says Bollinger. “It targets the body as a whole by using special exercises and repositioning to help the body function more efficiently as one unit.”

Very aware of the fast-approaching Olympic games, the physical therapists wasted no time in beginning treatment. Attending practices, visiting with the coach, consulting the trainer and guiding and training the women, Bolligner, with Vigen’s support, used postural restoration to quickly get the women back on track. “With this intensive program, we were able to achieve excellent results quickly, accomplishing about two months’ traditional strengthening in just one-and-a-half weeks,” Bollinger says.

Bollinger and Vigen were very pleased with the women’s progress. “It was very exciting to treat these individuals and see the great results that occurred. It’s always rewarding when patients do well after therapy,” says Vigen. No one, however, could have been happier with the outcome than Maureen and Jamie. “The treatment really helped with the pain — it was such a relief!” Maureen noted. For Jamie, the therapy went above and beyond treating her symptoms; it even improved her pre-injury aim. “I learned so much about myself and my body. It [the postural restoration technique] will help me continue to improve my game,” Jamie said.

With the help of the MeritCare Bemidji physical therapists, Jamie and Maureen were able to overcome their injuries, regain their confidence and ultimately live their dream of competing in the Olympic games. During their time in Torino, the women, with the help of their trainer (who received guidance from Bollinger), continued their postural restoration exercises. Neither was bothered by her injury during competition.

Though the Olympics are over, both Jamie and Maureen plan to continue to use the techniques they learned during their treatment, whether injured or not. Jamie, in fact, never intends to stop. “I plan to keep curling for a very long time and I want to be sure my legs and body can keep up,” she says. “I will use the exercises for the rest of my life.”

Like Paul Bunyan and Babe, Jamie, Maureen and their peers on the men’s and women’s Olympic curling teams have become icons. Their hard work, dedication, talent and passion have captured admiration not only in Bemidji, but on a worldwide scale as well. The legend of the Bemidji Olympic curlers, however, is still being written. “The beauty of curling is that there’s always more to strive for,” says Maureen. “Now that we’ve gotten a taste [of the Olympics], we definitely plan to be back.”

The following article has been added to PRI references for Zone of Apposition.

This article provides evidence that lung volume reduction surgery (LVRS) improves spirometric parameters, lung volumes, diaphragm strength, increased diaphragm length (ZOA), and improvement in maximum exercise performance.

PRI techniques performed clinically are the non-surgical avenue for reducing hyperinflation and therefore achieving the same outcomes seen here with surgical intervention.

Ron, I was hoping you could give me some advice over the phone or by e-mail. I am writing a case study on a patient with a peer of mine and we used PRI with them. We are having a difficult time putting into words the “theory” and background behind the evaluation and treatment techniques. Obviously it makes sense to me, but it is a whole different ballgame when trying to explain it to someone especially on paper. Particularly in front of an evidence based audience. As you have mentioned before the evidence is there. However, it is not in a concise and fluid way. I have read a couple case studies that you have written and one Kyndy wrote. But that is still not clear.
Any help would be greatly appreciated.

Hi Kim-
Thanks for your email and on-going support of our PRI approach to positional influences on neuro-pathomechanic developmental patterns.

The “evidence” is there, but going to all the sources as they presently exist, hasn’t been put together for the general public as of yet. As an Institute (PRI), we are in the process of doing this.

Articles on zone of apposition (ZOA) will help one understand the asymmetrical roles of the two hemi-diaphragms in their influence on respiration and thoracic function. Please refer to our website for these articles and information on diaphragm positions, differences in size, asymmetrical attachment sites, etc. Respiration, intercostal and mediastinal motion is also controlled and influenced by visceral position of the pericardium on the left and liver on the right (Reddy et al, J. Thorac Cardiovas Surg. 1994). Contraction of the diaphragm during postural adjustments (Paul Hodges, Journal of Physiology, 1997) and the diaphragms influence on postural/abdominal function (Paul Hodges, Manual Therapy, 1999) also support the need to address respiratory issues and influences on postural asymmetry.

Rib cage mechanics influence on the spine and asymmetry of the spine can be found in numerous articles (too many to mention in this email) with respect to the most common curvatures to the prevalence of right rib humps. Rib cage mechanics is influenced by asymmetrical compartmental pleural and abdominal pressure, configuration and trans-diaphragmatic strength. (Kenyon et al, J Appl Physiol, 1997). Why do 98% of adolescents with a single thoracic curve, have apex curvatures to the right with accompanying rib humps? (K. Song, Journal of Musculoskeletal Medicine, 1993)

Communication, swallowing, language, speech and ‘handedness’ reflects the left hemispheric ‘command center’ as well as proximal muscle involvement of the contralateral limbs (Bagesteiro et al, J Neurophysiology, 2002). “Dominant arm tasks were most almost exclusively associated with activities requiring precision in interjoint coordination and trajectory formation”. Slow, deliberate, controlled, organized, cortical motor encoding is correlated with manual skills developed by the left hemisphere (Volkmann, et all, J Neurophysiology, 1998 and Gabbard et al, JOSPT, 2002)

There are postural origin theories on asymmetrical development (Day and MacNeilage, J Comp Psychol, 1996), vestibular asymmetry theories (Previc, Psychol Rev., 1991). Developmentally tonic lumbar reflexes described in the literature by Tokizane (1951) and Brunnstrom (1970) are elicited when the “position” of the upper trunk is changed in relation to the pelvis. We pick up an object and proceed to throw it with our right hand because our upper trunk rotates to the right initially and the pelvis to the left, as weight is born on our extended “dominate” right leg with the left lower extremity flexed (Barnes, Crutchfield, 1978). Our diaphragm and adjoining psoas on the left allow this activity to occur more easily because of visceral orientation of the heart, stomach and liver (left upper quadrant to right lower quadrant axis) and neural-motor development of this amphibian reaction at the age of six months (Fiorentino, 1972).

In addition to these evidence-based comments on respiratory influences on asymmetry, cortical-hemispheric influences on neuromotor developmental strategies of proximal vs. distal stability on the right vs. the left, rib cage dynamics reflecting diaphragm influence and size, neurophysiology of motor development on ATNR, Moro, and other reflexes in the frontal, sagittal and transverse planes, there are those mentors; Buchholz, Schamberger, Gracovetsky, Myers, Lee, Busquet, Mezieres, Vleeming and Chaitow who will all agree we operate through patterns of ‘polyarticulated’ muscle.

It is also my strong belief that the mandible, sphenoid and temporal bones influence forward head posture, asymmetrical tonic neck reflexes, body on head righting reactions and respiratory pathomechanics that lead to forward head posturing, COPD and asthmatic activity, fibromyalgic sleep habits, scoliosis, T.O.S., hyperinflation cervicalgia headaches all which can be referenced easily through the dental community and all of which I have treated successfully without surgical intervention through the use of PRI techniques and intervention. Through my experience and with clinical documentation at the Hruska Clinic, strong evidence-based clinical data that supports the Postural Restoration Institute™ approach towards intervention and treatment of pathomechanics to restore balanced integrated function and respiration exists. Please refer to our evidence-based summary of “Postural Respiration and Myokinematic Functional Relationships”. Once a pattern of neuromuscular, respiratory, and circulatory system activity is identified, restoration of sphenoid, sternum and sacrum orientation and ‘rest’ position can begin.

Hopefully, Kim, you’ll appreciate we have a lot of work ahead of us. But those of us who understand these ‘system relationships’ will further develop this system evidence-based research to this date through an integrative approach by promoting sequential, specific approaches to a multi-system, bipedal, machine that functions with asymmetrical patterns of movement.

Best Regards,

Ron Hruska, MPA, PT
