From prints to prison: Forensic podiatry and gait analysis gain ground

Increasingly, lower extremity experts are being called on to assist with crime scene investigations by analyzing footprints, shoe prints, and the gait patterns of shadowy figures on security videos. For members of this fledgling field, as Sherlock Holmes famously said, the game is afoot.

Knee OA in amputees: Biomechanical and technological considerations

The risk of knee osteoarthritis in the intact limb of longtime unilateral amputees is much higher than in non­amputees, and the range of potential contri­buting factors is even more complex. Optimizing prosthetic fit and function, in addition to more conventional OA interventions, can help address gait issues that contri­bute to knee joint degeneration.

Patellofemoral pain subgroups: A critical first step toward personalized clinical intervention

Researchers from the UK have identified three subgroups of individuals with patellofemoral pain (PFP) that can be determined using simple evidence-based clinical tests—a key first step toward developing targeted treatment strategies as part of the ongoing effort to improve PFP outcomes.

Mouthguard mysteries: Can wearing one really improve athletic performance?

Multiple studies suggest that mouthguards, designed to protect athletes from dental injuries during contact sports, may also help improve muscle force and power. But plenty of other studies have found no such ben­efits, and even the experts aren’t sure what to believe.

Women’s Work: Overcoming gender barriers in lower extremity specialties

In lower extremity healthcare, as in politics, it hasn’t been easy for women to succeed in traditionally male-dominated roles. The gender demographics have shifted toward parity over time—in some specialties more than others—but challenges still remain.

A Finer Pointe: Visualizing the ankle’s response to ballet’s toughest task

The use of detailed orthopedic imaging to examine dancers’ ankles while in the en pointe position offers insight into the biomechanical demands associated with a position that, although highly unnatural, is nevertheless essential to a ballerina’s performance.

Smoking & knee OA: From clinical controversy to therapeutic possibility

Experts say perplexing studies suggesting that smoking may be protective against the development of knee osteoarthritis (OA) should not deter clinicians’ efforts to discourage smoking—even in patients who are at risk for OA.

Biomechanics of propulsion: Implications for AFOs

For many patients, the ability of an ankle foot orthosis to enhance propulsion is key to improving gait efficiency and reducing fatigue. But experts are only beginning to understand the biomechanical complexities that influence propulsion, which start with push-off but don’t end there.
