On differences between PRI and MSI…I am trying to understand what Postural Restoration techinques are and their differences from other evaluation and treatment techniques. My overall question is how is this framework different from the Sarhmann system of MSI (muscles systems impairment or Muscles systems balance)? Thanks for the great question! Dr. Sahrman’s major concepts of force couples and kinesiopathological model components are respected by Postural Restoration Institute (PRI) therapists. PRI is challenged, however, by her underlying premise that “efficiency and longevity of the human biomechanical system requires maintenance of precise movement of rotating segments” and yet her theory does not reflect the natural asymmetrical organizations of the body. Her major hypotheses, corollaries and concepts of index of system balance, mechanism of system imbalance, common imbalances and correction principles are all respected and appreciated. “Repetition, movement imbalances” and “paths of least resistance” do have an impact on the treatment approach used and “common faults and failures”. But, her correction principles do not necessarily reflect PRI’s approach of objectively recognizing and managing asymmetrical movement related imbalances or insufficiencies. For example, those who follow a “complete exam of movement system and the interaction of total biomechanical system-base, modulator and biomechanical” should recognize that the musculoskeletal connective tissue is arranged very differently on the left and the right side of the body and will never be symmetrical and because of it’s natural asymmetrical patterning will contribute to very predictable and organized paths of instantaneous center of rotation (PICRs) that are and always will be different on the contralateral side. The cardiopulmonary system, central nervous system and the skeletal muscle system do not promote function that always follow “paths of least resistance”. For example, your right diaphragm will always be a stronger muscle of respiration than it’s counterpart on the left, not because of paths of least resistance. And if you have a cross bite at your lateral incisors on the left, or a class II bite on the right and a class I on the left, or an anterior non-reducing TMJ disc, or non-reducing lateral visual midline shift influencing your vestibular function and compensative balance “strategy”, or a unilateral dependency on spinal reflexes, or a hallux limitus issue, etc, etc…your success of restoring “PICR to the kinesiologic standard” will be very challenging and difficult at best. “Training patterns of muscle recruitment, correcting postural habits and putting patients in control” requires a good understanding and appreciation of the normal, most consistantly existing asymmetrical patterns of the human body; and the normal influence or influences of these patterned polyarticular chains of muscles on the human axial and appendicular postural kinematics. PRI has created resources, educational opportunities, research, and patient-care programs to assist those who wish to maximize their assessment and treatment skills of the very natural organized and predictable asymmetrical human body with emphasis placed on respiration, myokinematics, neuromuscular applications and postural imbalances. PRI outlines these common integrated patterns and specifically outlines treatment approaches using some of Dr. Sahrman’s concepts along with ardent alignment and balance manual and non-manual techniques to restore normal reflexive, hemispheric movement without using compensatory neuroplastic adaptation patterns. PRI outlines when dentistry, podiatry, pulmonary and optometry, specialization is required to assist in this process. Thanks again for the opportunity! |
