Biotensegrity—The Structure of Life
Published in David Lesondak, Angeli Maun Akey, Fascia, Function, and Medical Applications, 2020
Accurately perceiving one’s position in space and time (i.e., haptic perception, as opposed to tactile perception) based on a tensegrity model has been well-described by Turvey and Fonseca.39 As a model, they employed both mechanical disturbances and tissue deformation. One only has to touch the surface of the skin in any location of the soma and the entire organism is aware of that touch. Individuals can further perceive its precise location, depth, force, and speed as well as its static or dynamic nature and more. While large numbers of patients worldwide suffer with inexplicable postsurgical pain,40 modern medicine can now confidently turn to the new field of mechanobiology and biotensegrity to help explain, and potentially obviate, the physical forces at play. When fascia and other connective tissues are disrupted, due to surgery or other invasive disruptive treatment modalities, changes to the biotensegral architecture can result in changes to intracellular biochemistry, gene expression, gross physical function, and symptomatic pain.

Haptic perception refers to brain functions that interpret information received through tactile (touch) and kinesthetic (movement of the body and muscles) senses and is essential for developing motor control. Tactile perception involves discriminating textures and geometric shapes. Kinesthetic perception includes balance skills and sensitivity to direction or position. Children with a tactile deficit may have problems manipulating objects because of the lack of meaningful information provided by the sense of touch, whereas a kinesthetic deficit could lead to problems in balance and spatial orientation.
Biotensegrity

Tensegrity structures are fully structurally integrated, so that an external force will instantaneously change the shape of the entire structure. This allows for instantaneous body-wide communication via the tensional continuity. This insight has been eloquently communicated in terms of haptic perception [13] – our ability to perceive objects and our environment through touch. It seems obvious that this ability would be determined by our sensory nervous system. However, if your eyes are closed and a tennis racquet is placed in your hand, you will quickly surmise that it is a tennis racquet. Without opening your eyes, you would likely be able to use your other hand to touch near the sweet spot on the face of the racquet. There is an instantaneous perception of the shape of the object by holding it. Turvey and Fonseca have hypothesized that this ability is a function of the body-wide tensegrity system composed of “connective tissue and the conjunction of muscular, connective tissue net, and skeletal (MCS) as the body’s proper characterization [14].”
Assume a Spherical Chicken: Analytic Constraints, Inertia Tensor Information, and Wielded Rod Length Perception
Published in Journal of Motor Behavior, 2019
For haptic perception, the relevant stimulus array encompasses force-based mechanical variables, with respect to some defined arrangement of perception-action system components in delimited events. In a classic example, Solomon and Turvey (1988) demonstrated that participants could haptically perceive the lengths of unseen hand-held rods by wielding. They concluded that the rods’ moments of inertia were the relevant mechanical variables supporting such perception. Subsequent research, yielding hundreds of additional papers, has consistently reinforced that conclusion (see reviews in Carello & Turvey, 2000, 2004, 2015; Turvey, 1996; Turvey & Carello, 1995, 2011). The moment of inertia tensor (Solomon, Turvey, & Burton, 1989) captures all three orthogonal principal moments of inertia (i.e., those about axes through the center of mass). Hypothetically, the inertia tensor completely specifies rod length, as well as other object properties. This body of research has been widely cited as supporting Gibson’s (1966) information-based perception theory.

Subjective haptic perception (SHP) has been accepted to represent mass-based proprioceptive information and tactile cues from the hands, arms, and shoulders, as well as the trunk and neck, involving force-related cues from the proprioceptive kinetic chain. In addition, it contributes to the body image in the proprioceptive perception of spatial orientation manner (Dietz, Gollhofer, Kleiber, and Trippel, 1992). The total haptic perception improved in the CSE and BBAT groups in this study. SHP for the 45° right and 45° left lines improved in the CSE group, whereas it improved for the 45° right line only in the BBAT group. This may indicate that BBAT has a positive effect on skin, muscle, tendon, and joint mechanoreceptors stimulation, in the manual exploration of an object in space. In addition, CSE may have stimulated proprioceptive sensors, which encode the muscle lengths and joint angles. Subjective haptic vertical perception measurement method has also been validated previously by Kerkhoff (1999). Kerkhoff (1999) reported the cut-off-score for the constant error as ±2.5° for the SHP.
