Alley Introduces the “Biotensegrity Bridge” for Human Device Interfacing

By | Biodesigns, biomechanics, Food for thought, HiFi, Prosthetics, Socket Technology

In the March 2021 issue of the O&P Edge, Randall Alley, CEO and Head of User-Interface Technology, notes the issues with existing prosthetic socket designs and introduces a new model to consider for attachment, the Biotensegrity Bridge™, and describes how the patented and patents-pending HiFi Interface™ System creates a stable and functional “bridge” for attaching prosthetic devices.

“Since soft tissue (fascia) has a nonlinear stress/strain arrangement, traditionalists have incorrectly applied linear laws using levers and pulleys (mechanical physics) to explain the effects that the forces of gravity and tension elicit on our bodies. Biotensegrity has emerged as a new model of structural biology that is in diametric opposition to the Newtonian model of linear mechanical forces we all learned in school. Understanding the dynamic and continuous relationships between the soft tissue (fascia) and fluids within the body opens up new and exciting opportunities for better understanding the nature and role of the human-device interface,” stated Alley. “I give you what I am terming the Biotensegrity Bridge™ as a better way to approach interface integration.”

biodesigns, in California, best known for their prosthetic interface/socket technology, recently delivered an advanced arm system during this unusual time as a result of the Corona Virus. “We consider our business vital to our patients and want them to know we are here for them,” stated Randall Alley, CEO, Chief Prosthetist for biodesigns. The system delivered included advanced technology including Alley’s patented and patents-pending HiFi interface design, Coapt Engineering’s Gen2 Pattern Recognition, College Park’s Espire Powered Elbow, and Motion Control’s Wrist Rotator and External Terminal Device (ETD2). The system will also be used with the user’s existing ilimb Quantum hand. biodesigns takes great pride in designing prosthetic systems that are appropriate for their users. “This user is long time wearer that has proven time and time again the many functional benefits he receives from his prostheses,” stated Alley.

“There is definitely a preconceived notion that a body-powered system is lighter, but with this HiFi socket it makes the arm feel just as light as body-powered. There is more stability across the entire length of the arm. There are no pinch points, way more degrees of freedom, more responsive, better connection to all the sensors.”

 

Amputee Has Shocking Reaction to her Socket

Arlene, a below-knee amputee for almost 20 years, couldn’t believe the difference between her traditional socket and her new HiFi. With the HiFi, “it feels so much more natural. I don’t have to think about walking. That’s Amazing!”  In my old socket, it “feels like I’m going to go down. The knee is going to buckle. It’s a little scary.” Arlene shows the HiFi can help users of all ages. Everyone can benefit from HiFi’s ability to provide added stability and control.
