Expanding Our Understanding of Chronic Ankle Instability

Research is showing that it’s not “just an ankle sprain,” but rather the first step on a perilous journey to physical instability and lower quality of life. The clinical presentation of chronic ankle instability (CAI) has been defined as the perceived or subjective instability with feelings of giving way, pain, and recurrent sprains.

Gait Biofeedback and Impairment-based Rehabilitation

In a study that debuted at the National Athletic Trainers Association virtual meeting and was subsequently published later, a multidisciplinary team of clinicians sought to analyze the effects of visual gait biofeedback along with impairment-based rehabilitation on gait biomechanics in a group of patients with chronic ankle instability (CAI).

The Dirty Truth About Being Biped

What bears don’t know didactically about forces, shock, and kinetic chain, they understand naturally, instinctually, and it is evidenced by the way they move. Bears can stand on two legs, play, pose, and walk as bipeds do, but when it comes to motion involving speed, safety, or…

Expert Opinion: Quantification of Arch Height in a Foot Orthotic: Defining A Standardized Methodology

Science and quantification are long overdue in the orthotic work that we do on a daily basis. The process of capturing the anatomical arch, creating a positive model, and managing arch fill has been solely a decision of those trained in the art.

Overlooked Arch In The Foot Is Key To Its Evolution And Function

A long-overlooked part of the human foot is key to how the foot works, how it evolved, and how we walk and run, according to a Yale-led team of researchers. The discovery upends nearly a century of conventional thinking about the human foot and could open new avenues to explore in evolutionary biology as well as guide new designs for robotic and prosthetic feet, said the study team.

From the COVID-19 Frontlines


A mechanistic model and therapeutic interventions for COVID-19 involving a RAS-mediated bradykinin storm

While COVID-19 is known to affect the body in numerous ways that are yet not clearly understood, several researchers have begun to focus on what is known: SARS-CoV-2, the virus that causes COVID-19, starts by infecting certain cells in the nasal passage. Stopping, or at least slowing this initial foothold may prove a powerful strategy for taming this pandemic.

New Treatment Options Focus on the Nose

FIRST-EVER RESEARCH NETWORK TACKLES DFU COMPLICATIONS

Six research institutions are launching the first-ever multicenter network to study diabetic foot ulcers (DFUs), which are the leading cause of lower-limb amputations in the United States. The Diabetic Foot Consortium (DFC) aims to lay the foundation for a clinical trial network to test how to improve diabetic wound healing…

UT SOUTHWESTERN SCIENTISTS DEVELOP COOLING INSOLE

A new cooling insole developed by University of Texas Southwestern (UT Southwestern) scientists reduced the foot temperature of patients with diabetic neuropathy by several degrees, diminishing a significant risk factor for diabetic foot ulcers (DFUs).

SIMPLE TEST HELPS TO PREDICT, PREVENT FALLS

The “enhanced paper grip test,” validated by researchers from the Centre for Biomechanics and Rehabilitation Technologies (CBRT) at Staffordshire University, England, involves pulling a small card from underneath the participant’s foot while asking them to grip with their big toe (hallux).

DOD GRANTS $2M TO STUDY FALL-RELATED HEALTH OUTCOMES IN LOWER-LIMB PROSTHESIS USERS, MPKS

A $2,000,000 grant from the US Department of Defense’s (DoD) Congressionally Directed Medical Research Programs’ Orthotics and Prosthetics Outcomes Research Program has been awarded to a group of institutional collaborators to study fall-related health outcomes in lower-limb prosthesis users, including…
