High-impact sports expose athletes to greater risk of injury overall. Is there a way to prevent such trauma by applying the lessons of sports science? Stress fractures of the foot result from repetitive microtraumas and chronic submaximal loading of tissues. Among football players, the most common are the Jones fracture, a break in the fifth metatarsal between the base and the middle, and the…

High relapse rate from preseason injuries presents significant challenge for athletes and sports teams. Hamstring strain injuries are among the most common in sports, often leading to recurring problems or future injury. Marcus Elliott, director of P3 Applied Sports Science and a former muscle-injury specialist for the National Football League’s New England Patriots, conducted…

The decision often hinges on how a given intervention will affect the patient’s quality of life. How, then, to define optimal QoL for your patient, and to agree on the means to achieve it? As clinicians well know, diabetes puts patients at risk of foot ulcers that can lead to poor outcomes, evidenced by the 40% 5-year mortality in patients with newly diagnosed diabetic foot ulcers (DFUs).

The authors seek answers to clinical questions regarding the optimal program of eccentric exercises: Does type of tendinopathy predict success? What modifications to exercise duration and repetitions make sense? What is the likelihood of long-term pain relief afforded by such a program of exercise?

Leg-length discrepancy and its sequelae are best considered a syndrome affecting many regions of the body through the closed kinetic chain. Most cases require comprehensive, cross-disciplinary treatment. The authors present a novel scoring system for diagnosis.

People with PFP are less physically active than healthy controls, with regard to both steps per day and minutes of mild, moderate, and intense activity. Increases in activity-related pain may cause…

As a growing number of studies report associations between concussion and musculoskeletal injury risk, new research suggests concussed athletes may also have an increased risk of osteoarthritis later in life.

Lower extremity clinicians say ankle foot orthoses, rocker-soled shoes, and other orthotic interventions can benefit patients with peripheral arterial disease and intermittent claudication by making it easier for them to exercise, and research is starting to demonstrate these benefits.

Wearable sensors allow for the collection of running biomechanics data outside the laboratory in natural training environments, enabling clinicians to collect a large volume of information in a relatively short time to help identify and manage individuals who may be at risk for running-related injuries.

It’s not unusual for any practitioner to experience complicated emotions when a death or a terminal diagnosis disrupts the personal bond forged with a patient over many years, but experts say lower extremity clinicians often are not well equipped to deal with these emotions.

Clinicians know that handling a lacrosse stick or other types of sport-specific equipment can affect an athlete’s movement patterns in potentially harmful ways. Now researchers are beginning to quantify these types of effects and explore their clinical implications.

Clinicians in areas affected by hurricanes Harvey and Irma were prepared for issues involving preexisting lower extremity concerns, but were surprised by the number of cases they saw in the storm’s aftermath involving healthy people trying to function under extraordinary conditions.

High ankle sprains in collegiate athletes differ from lateral or medial ankle sprains in multiple clinically relevant ways. These include loss of sports participation time, mechanism of injury, rates of injury during competition versus practices, and the possible long-term risk of osteoarthritis.

Orthotic devices for hallux limitus are designed to limit first metatarsophalangeal joint motion while providing cushioning and plantar pressure distribution. A lack of quality research on conservative treatment of the disorder, however, forces clinicians to rely on their own experience.

Achilles tendon ruptures are severe injuries that are associated with a long recovery and significantly affect an athlete’s ability to function at a high level. In devising strategies for rehabilitation and return to play, the goal of clinicians and athletes alike is to try to minimize this impact.

In spite of advancements in research and subsequent modifications to running footwear design, rates of running-related injuries have not decreased. That may be because researchers and designers have been focusing on the wrong variables.

The ankle is a frequent site of arthropathy in patients with hemophilia, but orthotic devices and orthopedic shoes can help relieve this pain. New research suggests that…

Soft braces are not designed to change lower extremity alignment or joint forces, but research suggests they may influence knee and ankle biomechanics in other ways, including by enhancing proprioception. This line of investigation could open the door to new therapeutic opportunities.

Achilles tendon lengthening and gastrocnemius recession both increase ankle joint dorsiflexion and reduce plantar forefoot pressures in patients with diabetes and equinus deformity, but experts continue to debate which is best for managing forefoot ulcers and minimizing reulceration.

Research suggests that a simple step-down task has a strong relationship with frontal plane ankle kinematics during walking and jump landing, and may be one method of screening or assessing for increased inversion—and, in turn, increased risk of future ankle sprain—in clinical settings.

At a symposium in Cape Town, South Africa, an orthotist demonstrated his technique for treating balance issues in patients with peripheral neuropathy using ankle foot orthoses (AFOs), and a team of researchers theorized about evidence-based concepts that could help explain his findings.

Factors related to joint loading during running contribute to the development of stress fractures in the femoral neck and other lower extremity structures. Research suggests these loading parameters can be reduced by altering running foot strike pattern, stride length, speed, and step rate.

Clinical prediction rules (CPRs) are intended to improve patient care, but critics have suggested that—for a number of reasons—the opposite may be true. Lower extremity experts interviewed by are in agreement that, ultimately, even the best CPRs should be only one piece of the clinical puzzle.
