PRACTICAL MATTER FOR CLINICIANS: Women Are Biomechanically Distinct From Men When They Run

Learn how men and women are constructed differently—and therefore why they each have a distinctive running gait—to be better equipped to manage, and prevent, female-specific lower-extremity sports injury. Starting at puberty, sex hormones begin to affect changes in bone and lean body mass—changes that are different in females than in males.

Addressing Gender Matters On the Field, In the Locker Room…Everywhere

iStockphoto.com #1132012561


For decades, numerous research studies have shown that physical activity and sport play a significant role in positively shaping children’s health and emotional well-being. But, as we learn more about biology and psychology, it becomes clear that gender matters in ways not conceived of when John F. Kennedy became President in 1961 and re-energized the President’s Council on Youth Fitness, predecessor of the more recent President’s Council on Physical Fitness and Sport.

We know today that athletic participation, particularly in children, can favorably influence general health, self-esteem and body image, body weight, social relationships, quality of life, and educational attainment. But we also know that the playing field isn’t exactly level. In addition to biological differences (think: Q angles and a disproportionately high rate of ACL injury), girls and women who play sports often have to navigate the conflicting cultural messages about what it means to be a girl or woman and what it means to be an athlete.

The good news is that, more and more, they are not alone in this struggle. A recent academic research study and a new national report point to the increasing breadth of professional help available to girls and women who want to participate in sport—and the quantifiable impacts that those professionals provide.

From the editor: Time to disrupt pediatric care

In many areas of pediatric medicine, treatment for kids hasn’t caught up with consequential advances in adult healthcare. The FDA, for example, estimates that development of child-specific medical devices typically lags five to ten years behind new adult technologies.

A story in this issue profiles two companies trying to disrupt a current standard of care for kids (see “Biotechnology startups break into pediatric care,” page 39). One, Augment Therapy, was founded by Lindsay Watson, PT, MPT, a pediatric physical therapist developing a software platform that blends telemedicine and augmented reality, the combination of real-world and interactive digital environments, to give children a fun, immersive physical therapy experience.

Watson thought of the solution several years before starting to develop it, thinking someone else would soon see the same possibilities and create the tool she envisioned. Tools did appear, but Watson, looking at the teams behind them and seeing that “there wasn’t a clinician in sight,” knew she could do better.

Glaucoma = Gait Changes and Fall Risk

early 60 million people worldwide will be affected by primary open-angle glaucoma (POAG) in 2020. The condition, a leading cause of irreversible blindness, typically occurs in people > 40 years of age; risk increases with age. The condition is known to cause difficulty walking, particularly when lighting levels differ, such as on steps, or when crossing the street.

Inverse Association Between Coffee and Falls

European researchers have found an inverse association between habitual (ie, daily) coffee drinking and the risk of falls in the elderly—and that inverse association was particularly strong among those who drank caffeinated! The association also held (although not to the same extent) for a lower risk of injurious falls.

EXCERPT: Foot Orthoses Alter Lower-limb Biomechanics in Basketball Players—Flat Feet or Normal Arch

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.

Infographic on Running Related Injuries

Biomechanical risk factors associated with running-related injuries: a systematic review. The incidence and prevalence of running-related injuries (RRI) is high. Biomechanical factors may play a role in the etiology of these injuries. This systematic review synthetizes biomechanical risk factors related to the development of RRI.

Website Helps DMEPOS Suppliers Prepare for Competitive Bidding

A new website, DME CBP Education, brings together publicly available information from government sources to help suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) prepare for Round 2021 of the Centers for Medicare & Medicaid Services’ (CMS’) Competitive Bidding Program (CBP). The DMEPOS CBP was established by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA).
