Taking a Load Off: An Update on How Biomechanics Research is Shaping the Future of Conservative Treatment for Knee OA
By Monica R. Maly, PT, PhIn a recent study in The Lancet, Cui et al estimated there are ~654 million people age 40 and older around the world who have knee osteoarthritis and an additional ~87 million individuals age 20 and older who have already been diagnosed.

National Biomechanics Day (NBD)—April 7, 2021—is a worldwide celebration of biomechanics in its many forms for high school students and teachers. Sponsored by The Biomechanics Initiative, NBD is in its 6th year of celebrating all things biomechanics. NBD’s goal is to accelerate the growth and impact of biomechanics science and application by introducing biomechanics to young people, namely high school students. Continue reading
Center of pressure is a critical biomechanical measure of human postural control and gait, particularly in chronic ankle instability. Evidence from biofeedback studies reveals COP may be modified to improve gait and functional movement.

The human foot is an engineering marvel, consisting of 26 bones, 33 joints, and more than 100 muscles, tendons, and ligaments. But it is the unique and elegant load-sharing system of the longitudinal arch that makes human locomotion possible. This author explains how.

We all strive for healthy and happy lives, and many of us are fortunate to reach these goals. For these people, living in the physical world is not a challenge but a pleasure. The world does not overwhelm them; rather, it interacts and plays with them in enjoyable ways. To quote Walt Whitman, we “swim with the swimmers, wrestle with the…

Master Foot & Ankle Biomechanics with New & Improved Class “When the Feet Hit the Ground Everything Changes”
When the Feet Hit the Ground….Everything Changes is a beginner to intermediate live/in person course designed to advance the mastery of foot & ankle biomechanics. As the first point of contact to the ground, the feet play a major role in lower-extremity chain mechanics. With proper treatment and mechanical correction, debilitating injuries can be both overcome and prevented. Continue reading
National Biomechanics Day (NBD) is a worldwide celebration of biomechanics in its many forms for middle- and high-school students and their teachers. Designed to introduce biomechanics science and its applications to young minds around the world, the event seeks to teach young people about all that biomechanics contributes to society with the hope of encouraging them to pursue it as a career.

Clinicians use a variety of in-shoe heel lifts to treat a range of musculoskeletal conditions. The mechanics of how these orthotic devices work, however, is unclear. So a group from LaTrobe University in Australia put together a study that asked this question: Do heel lifts affect lower limb biomechanics and muscle function during walking and running? Continue reading
Flat-footed persons are believed to have poorer jump performance compared to those who have a normal arch. Foot orthoses are commonly used to support the deformed foot arch and improve normal foot function. However, it is unclear if use of foot orthoses affects jump performance in athletes.

The International and American Societies of Biomechanics were founded in 1973 and 1977, respectively. Coincident with the expansion of Biomechanics during the following decades, fitness and health have moved out from under the realm of medicine and are rapidly overtaking the realm of the personal—the personal lifestyle to be more exact (think yoga, yogurt, and yoga pants).

National Biomechanics Day (NBD) 2018—April 11, 2018—continued building excitement for the field by engaging 11,000 young students across 150-plus sites around the globe. The home-grown events allow high school (and younger) students to experience first-hand a field that underlies orthopedics, exercise physiology science, physical therapy, and countless other fields that involve human movement and performance.

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.

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.

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.

Two studies presented at the IOC World Conference on Prevention of Injury and Illness in Sport, held in Monaco in March, shed light on the complex ways in which aspects of landing contribute to risk of ankle sprain in volleyball and basketball—both sports in which ankle sprains often occur when one player lands on another’s foot.

The American Society of Biomechanics has begun plans for National Biomechanics Day (NBD) 2017, scheduled for April 6. Continue reading
Athletes with low neurocognitive scores are more likely than their higher-scoring counterparts to demonstrate landing mechanics associated with anterior cruciate injury (ACL) risk, according to research from the University of Florida in Gainesville.

The American Society of Biomechanics (ASB) on April 7 had its first National Biomechanics Day, a nationwide, synchronized event held at labs and other biomechanics facilities around the nation to educate high school students and their teachers about the field. Continue reading
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.
