What is Biotensegrity? Dr. Stephen Levin @ Fascia Research Congress 2015

TL;DR

The body functions more efficiently when viewed as a tensegrity structure, with bones floating within a complex tension network, eliminating sheer and moments and distributing loads evenly throughout the body.

Transcript

My name is Stephen Levin, I’m an orthopedic surgeon. I was in practice for 50 years. 40 years ago I developed a concept based on Kenneth Snelson and Buckminster Fullers work on tensegrity. And the simplest way to explain it to you is the present concept of the body is based on a wagon wheel model, where you are vaulting from spoke to spoke and then... Read More

Key Insights

• 🧑‍🦼 The present concept of the body as a wagon wheel model is flawed and inefficient.
• ☠️ The tensegrity model turns the body inside out, with bones floating within a tension network, eliminating sheer and moments.
• 🫵 Viewing the body as a tensegrity structure provides more efficient movement, load distribution, and stability.
• 🧡 The tensegrity model is applicable to a wide range of organisms and body types, offering a universal understanding of body mechanics.
• 🎚️ Tensegrity is hierarchical, starting from the subcellular level and working up to the organism level, maintaining consistent mechanical principles.
• 🖐️ The fascia plays a significant role in the tension network of the body, emphasizing the importance of tensegrity in understanding body mechanics.
• 🥳 The body cannot be viewed solely as a lever system, as it does not account for the suspension and movement of various body parts.

Questions & Answers

Q: How does the tensegrity model differ from the traditional wagon wheel model of the body?

The tensegrity model views the body as a complex tension network, with bones floating within it, eliminating sheer and moments. In contrast, the wagon wheel model relies on compressive loads and solid columns, leading to inefficiency and uneven distribution of loads.

Q: Why is the tensegrity model more energy efficient?

In the tensegrity model, the body is inherently stable, making it more energy efficient compared to the unstable column structure of the wagon wheel model. This stability allows for more efficient movement and load distribution throughout the body.

Q: How does the tensegrity model explain the flexibility of long structures like a dinosaur's neck or tail?

In a tensegrity system, the bones are enmeshed in a tension network, allowing for stabilization of long structures. By stiffening one muscle, the entire system can be stiffened, maintaining stability and preventing excessive flexibility.

Q: How does the tensegrity model apply to different organisms and body types?

The tensegrity model is a universal mechanical system that can explain the mechanics of various organisms, from one-cell organisms to insects, fish, birds, and humans. It does not require changing principles for different body types.

Key Insights:

• The present concept of the body as a wagon wheel model is flawed and inefficient.
• The tensegrity model turns the body inside out, with bones floating within a tension network, eliminating sheer and moments.
• Viewing the body as a tensegrity structure provides more efficient movement, load distribution, and stability.
• The tensegrity model is applicable to a wide range of organisms and body types, offering a universal understanding of body mechanics.
• Tensegrity is hierarchical, starting from the subcellular level and working up to the organism level, maintaining consistent mechanical principles.
• The fascia plays a significant role in the tension network of the body, emphasizing the importance of tensegrity in understanding body mechanics.
• The body cannot be viewed solely as a lever system, as it does not account for the suspension and movement of various body parts.
• Tensegrity allows for omnidirectional movement, making it more adaptable and applicable in various environments, including space.

Summary & Key Takeaways

• The traditional model of the body as a wagon wheel, with compressive loads and solid columns, is flawed.

• The tensegrity model, inspired by Kenneth Snelson and Buckminster Fuller, turns the body inside out, with bones enmeshed in a tension network.

• This model eliminates sheer and moments, making body loading more efficient and distributing loads evenly throughout the whole body.
