Helical tensegrity as a structural mechanism in human anatomy

Published:January 24, 2011DOI:https://doi.org/10.1016/j.ijosm.2010.10.002

      Abstract

      Tensegrity is a structural system popularly recognised for its distinct compression elements that appear to float within a tensioned network. It is an attractive proposition in living organisms because such structures maintain their energy-efficient configuration even during changes in shape. Previous research has detailed the cellular cytoskeleton in terms of tensegrity, being a semi-autonomous system amenable to such analysis because of its size. It has also been described at higher levels in the extra-cellular/fascial matrix and musculo-skeletal system, but there are fewer syntheses of this.
      At a fundamental level, the helix and tensegrity share common origins in the geometries of the platonic solids, with inherent hierarchical potential that is typical of biological structures. The helix provides an energy-efficient solution to close-packing in molecular biology, a common motif in protein construction, and a readily observable pattern at many size levels throughout the body. The helix and tensegrity are described in a variety of anatomical structures, suggesting their importance to structural biology and manual therapy.
