Tensegrity Fatigue Fracture Theory

The book "How the Brain Brings Healing" by Mr. Norman Doisi, which our association emphasizes as a general teaching material.

In the Tomatis Method (a type of auditory training) introduced in this book, emphasis is placed on listening to music through headphones with bone conduction speakers.

Bone conduction is also applied to hearing aids and earphones, and is known as a method of transmitting vibrations through the skull to the brain. A bone.

Among the more than 200 bones in the human body, the smallest bones are the auditory ossicles (malle, incus, stirrup). Although it is a really small bone of only 2 to 3 mm, it is a very excellent vibration transmitter that amplifies the vibration transmitted to the eardrum by 22 times.
It turns out that all other bones, to a greater or lesser extent, have the vibration-conducting qualities of the skull and ossicles.

In general, bones are considered to be a material that supports the skeleton - a hard and inorganic image - but in fact, it is an excellentconductor(→ Explained on this page) and at the same timevibration transmitterIt can be said that it is.

Furthermore, the following experiments show that such vibration transmission functions are not limited to bones, but also joints and soft tissues such as skin, muscles, and ligaments.

A comparative study of how the resonance frequency, damping ratio, and vibration mode are affected by the presence or absence of joints and soft tissues, using a formalin-fixed human wet tibia (bone below the knee) for dissection training. There is a famous experiment that

According to this, it was found that joints and soft tissues not only absorb vibration but also vibrate together with the tibia. From this, it was found that changes in skin and muscle tension directly affect bones.

This fact is consistent with clinical observations. In most cases of shin splints and tibial stress fractures, muscle and skin tone abnormalities of the affected leg are observed. A careful palpation will tell for sure.

Disruption of muscle coordination in the lower extremities, especially in athletes, such as simultaneous contraction of flexor and extensor muscles, leads to a decrease in antigravity and an increase in compressive stress on bones, resulting in a decrease in Young's modulus (deformation strength level). is also connected.

As an aside, when I was a university student (architecture department), during a concrete compression experiment, I suddenly imagined in my head, "What would happen if the same experiment were performed with human bones?" I once felt a throbbing pain in my shin when it was destroyed.

In retrospect, that experience had a wonderful impact on my future life (bitter smile). I never dreamed that I would call such pain a soft pain...

Let's get back to the story. As mentioned above, in many cases of stress fractures, changes in skin and muscle tension around the affected area are observed. You might think it's a chicken-or-the-egg, but my clinical data almost certainly make me believe it's the latter.

in shortSkin or muscle hypertension or hypotonia that precedes stress fracturesIt is.

human skeletonteethtensegrity approximation modelEquivalent to Taiji Kajiwara, a world-famous geometer, has made a detailed report on the resonance characteristics of tensegrity (this pageYou can see a video of the "Resonant Tensegrity Model" at

Based on the content, it can be inferred that a unique resonance mechanism is latent in the human skeleton and, in turn, in the bones, and the author believes that this embodies the physically excellent elastic force and repulsive force. increase.

When the skin or muscles become overtensioned or undertensioned, this internal model of the skeleton (resonance characteristics) is impaired, resulting in a decrease in elastic capacity. As a result, the bones of the lower extremities are unable to disperse the stress against the load and the impact of jumping, etc., and this leads to shin splints and stress fractures.

in shortLoss of tensegrity resonance as a skeleton reduces the physical strength of the bone(In terms of tensegrity, compressive materials are equivalent to bones, and tensional materials are equivalent to skin and muscle).

Then, when do humans develop hypertension or hypotension in the skin and muscles?

The reason for this is brain fatigue. At our association, we define this reality as "cerebral metabolic dysfunction", which refers to a state in which the energy balance of the brain is extremely disturbed. Mental problems, chronic inflammation and glial cell dysfunction are assumed to be the background.

therefore,For cases of shin splints and stress fractures, care for brain fatigue (brain overwork) is of utmost importance, as well as treatment of the affected area...

That is, mind-body integrative therapy that combines mental care, dietary guidance (from gluten problems to FODMAP), and bodywork.

However, there are no sports orthopedic surgeons with such a perspective, so at present, only some medical practitioners belonging to the Japanese Society of Integrative Therapy can deal with both hard and soft aspects of stress fractures in amateur and professional athletes. I'm doing the treatment.
