The focus of SI on the balance of the myofascial tensional structures around the skeleton leads to a new appreciation of the body’s spatial geometry as an example of the Snelson/Fuller Tensegrity class of structures (Fig. 9). Traditional biomechanics sees the skeleton as a continuous compressional framework, like the superstructure of a crane, off which the muscles hang like the cables from a crane, moving the bones around. Individual muscles are often analyzed in terms of what action they would have if they were the only muscle on that skeleton -in other words, of approximating origin and insertion. Of course, no muscle operates singly, and increasing attention is paid in kinesiology to the synergistic actions of muscle groups unpredicted by these analyses of the individual parts (Fig. 10). SI views the bones as compressional struts floating within a sea of soft-tissue tension. In these structures, called tensegrity structures -contraction of the phrase ‘tension integrity’, implying that the integrity rests on the balance of tension members -the position of the floating struts rests on the balance of the tensional bands. In the human body, these are the soft-tissues, specifically the myofascial network (Fig. 11). In this view, an even tonal balance across the soft-tissues constitutes the place where the joints are least stressed, and where the individual will be most at rest, most poised for action, and most vividly attentive to all the changes within and without the body. The old model allows for thinking about the body locallyFthat a painful shoulder can be repaired solely by working on the failing structure at the local site. Because tensegrity structures are designed to distribute strain over the whole structure, this new model requires that any local changes be balanced globally to achieve lasting results. In other words, the tensegrity model fits well with the systemic view of spatial medicine, rather than the symptom-based view. The body itself seems to work over a continuum of structural solutions to its gravitational and mechanical challenges, from the ‘stack of blocks’ continuous compression type through the ‘filled balloon’ pneumatic type to pure tensegrity (Myers, 2001).
