Assessing articular function using FR®/FRC™ methodology

August 29, 2013

We posted a video similar to this one not too long ago looking at the assessment of joint movement…many said the video was ‘cut off’ at the ‘good part’….so here is a more extensive (although not at all complete) explanation of how aberrant joint motion vs. ‘normal’ joint motion is defined using the Functional Range Release (FR)® and/or Functional Range Conditioning (FRC)™ systems.

Note that the term ‘normal’ wr2 joint motion (as with other things) is usually simply defined as the ‘average’ amongst people. This is not a satisfying explanation as many cultural/social influences can alter joint motion and/or function….for example, chairs, shoes, cars, laptops, etc., were NOT part of the evolutionary process, yet they greatly influence mobility and how well modern people move. Is it ‘normal’ not to be able to sit in a full squat position comfortably? By the standard definition, in North America at least, the answer would be yes…from a human evolution stand point, the answer is ABSOLUTELY NOT.

@DrAndreoSpina: How about a new definition of ‘normal’ ROM? Normal ROMs are ANY motions that one has active, neurological control of

We define normal range not by angular measurement, but by joint function. What is normal isn’t necessarily optimal….but a ‘normally functioning joint’ can be safely trained to increase available range, while an ‘abnormal’, or ‘aberrant’ joint must be corrected before doing so.

An expansion of these concepts is presented at all Functional Range Release (FR)® technique, or Functional Range Conditioning (FRC)™ certifications
