Lower Extremity Review
Researchers have developed a new, data-driven way of fitting prosthetic legs, which could lead to better fitting prostheses, in less time and at a lower cost. The technology has been developed by Radii Devices and the University of Southampton, UK. The study shows that transtibial prosthetic limbs designed using the…
In an effort to address the ongoing challenge of gait impairment after stroke, researchers have developed an innovative rehabilitation approach known as FAST walk, an innovative, electromyography (EMG)-triggered system that synchronizes transcutaneous spinal cord stimulation with hip extensor stimulation.
Zimmerman Shoes, Orwigsburg, Pennsylvania, the United States’ oldest manufacturer of children’s shoes, has acquired Markell Shoe Company, Yonkers, New York, an orthopedic and corrective footwear manufacturer. The acquistion enhances Zimmerman Shoes’ product portfolio and…
An artificial intelligence (AI)-assisted model that combines a patient’s MRI and biochemical and clinical information shows preliminary promise in improving predictions of whether their knee osteoarthritis (OA) may soon worsen. Ting Wang of Chongqing Medical University, China, and…
For those living with obesity, who are known to exhibit differences in walking gait, speed, energy burned and more, fitness trackers often inaccurately measure activity–until now. Scientists at Northwestern University have developed a new algorithm that enables smartwatches to more accurately monitor the…
A team led by researchers at Pennsylvania State University (Penn State) developed a new fabrication approach that optimizes the internal structure of electrospun fibers to improve their performance in electronic applications. This novel electrospinning approach could open the door to more…
Massachusetts Institute of Technology (MIT) researchers have developed a bionic knee that can help people with transfemoral amputations walk faster, climb stairs, and avoid obstacles more easily than they could with a traditional prosthesis. Their innovation is now being used in conjunction with a…

Researchers from the University of Oxford and University College London have collaborated on the development of an artificial intelligence (AI)–enabled piezoelectric wearable device for accurate joint torque sensing, leveraging the unique properties of boron nitride nanotubes (BNNTs).
Researchers from Pennsylvania State University (Penn State) and China’s Hebei University of Technology aimed to accurately measure temperature and strain signals without crosstalk by using laser-induced graphene (LIG), a two-dimensional material. In doing so, they discovered that this material also has…
To reduce the likelihood of consequences caused by impaired blood flow, scientists from Lithuania have developed an ultrasonic foot stimulation device that can non-invasively improve blood circulation in the lower limbs, with the aim of preventing diabetic foot. This innovative device was created through a collaborative effort of…
Researchers from the National University of Singapore (NUS) have developed 2 microneedle technologies that have shown efficacy in accelerating diabetic wound healing in preclinical models by preserving the functions of proteins called growth factors, and removing undesirable inflammatory compounds.
Through creating a treatment adaptable to the different needs of patients—using a new 3D-printed hydrogel made from cow meniscus—researchers in the Perelman School of Medicine at the University of Pennsylvania (Penn) believe they may have unlocked a better fix no matter where an injury occurs in a meniscus.
Diego Guarin, PhD, an assistant professor of applied physiology and kinesiology in the University of Florida’s College of Health and Human Performance has developed an open-source computer program that uses artificial intelligence (AI) to analyze videos of patients with Parkinson’s disease and other movement disorders, thereby…
When Colorado State University (CSU) engineering student Garrison Hayes was 6 years old, he underwent a transfemoral amputation due to pediatric osteosarcoma. After limb-salvage surgery, Hayes played soccer, then skied, cycled, and became a Paralympic athlete in the javelin throw. All the while, he found the prosthetic feet he used to be…
