Crutches Reinvented for the 21st Century

Posted by Bryan Potok on

Crutches have been around since ancient times. It started as a T-shaped walking stick, which later evolved into the V-shaped design that we still use today. However, this design has a flaw—it’s uncomfortable. Around 85% of people report feeling pain in their hands, wrists, and shoulders when using standard underarm crutches.

The crutches are reinvented for the 21st century.

VA Develops Sensor That Gives Real-Time Data on How Your Socket is Fitting

Posted by Bryan Potok on

The U.S. Department of Veterans Affairs (VA) developed a prosthetic socket fit sensor that identifies pressure points within a socket. As of this writing, the technology is patented and is available via patent license agreement to prosthetic companies that would make or sell the device commercially.

Virginia Tech Researchers Are Developing Smart Prosthetic Sockets

Posted by Bryan Potok on

A team of researchers from the Virginia Tech College of Engineering are working on a solution to the volume issue, thanks to a $400,000 research grant from the National Science Foundation in late 2019. For three years, the team will dedicate their time to the study of volume loss and eventually develop smart prosthetic sockets to improve comfort and prosthetic performance.

E-Dermis Restores Sense of Touch

Posted by Bryan Potok on

When one loses a limb, the brain is unable to fully process and still sends signals. It will continue to send signals to that limb—this is the leading cause behind phantom limb pain. While this occurrence may cause discomfort, it gives prosthetic researchers hope to use these signals to continue improving prostheses until they feel and act like a biological limb.

Researchers at Johns Hopkins University sought to restore the sense of touch to prosthetic users by testing and developing an “e-dermis.”

Ottobock’s Harmony System Simplifies Residual Limb Volume Management

Posted by Bryan Potok on

Most prosthesis users—especially lower-limb amputees—complain that the volume of their residual limb diminishes throughout the day. In fact, by the time lunch rolls around, adding another prosthetic sock is common. Ottobock offers a solution to this problem by creating a system that actively manages residual limb volume.
