These authors found a dose-response relation between body mass index and the clinical consequences of knee osteoarthritis. High physical activity level was associated with low BMI and contributes to preventing the clinical consequences of KOA.

Having performed thousands of bike fits, I now believe that the bicycle’s crank arm length is the most important factor when performing a bike fit. Every other anatomical dimension and joint angle is based upon the length of the crank arms; therefore, this is the first factor to address when performing a bike fit.

Untreated lymphedema can play a significant role in chronic wounds. Manual Lymph Drainage (MLD), performed by a Certified Lymphedema Therapist (CLT) is standard of care for the management of lymphedema of all types, not just advanced disease.

Active children may play through the micro-traumas creating this potentially damaging condition. Keep OCD in mind when children report pain in the ankle, particularly when BMI is high. Juvenile osteochondritis dissecans (OCD) of the talus is a rare condition in the pediatric population…

In their own words, 2 stroke survivors who use different AFOs, discuss the mismatched perception of how the ankle foot orthosis represents long-term disability but is a resource for independent safe mobility. Three-fourths of all strokes occur in adults older than 65 and as age increases…

Given its lack of efficaciousness in decreasing bioburden, normal sterile saline may not be the best solution for this important task. Chronic hard-to-heal wounds pose a significant burden on both patients and the health care system. Chronic wounds, whether pressure, arterial, venous, or wounds from multiple causes…

With benefits similar to traditional training practices but with less work, BFR exercise is gaining ground in rehabilitation settings as well as athletic training rooms. The intentional manipulation of blood flow during exercise, commonly referred to as blood flow restriction (BFR) exercise, has piqued the interest of scientists and practitioners alike over the past two decades.

Changes in Product-related Lower Extremity Injuries Treated at Emergency Departments During the COVID-19 Pandemic
During 2020, emergency department (ED) visits in the United States (US) not related to COVID-19 declined during the COVID-19 pandemic, particularly for certain populations and certain types of illness or injury. This study described product-related lower extremity injuries managed at EDs during 2020 and compared it to previous years.

So much has happened, I don’t even know where to begin. This is time for reflection and appreciation for where we have been and where we are going. All our lives and businesses have been changed forever. This pandemic has affected us in so many ways personally and professionally. In many ways, our eyes and hearts were opened.

There is no question that walking is generally a good form of exercise. However, it is not always appropriate during all phases of pregnancy, nor does it adequately prepare a woman for delivery or the fourth ‘Tornado’ Trimester. Long gone are the days of no lifting and putting your feet up during pregnancy. Pregnancy is the time to ‘train’ for a postnatal marathon that will last several years in a sleep-deprived state.

Pickleball is a paddle sport that combines many of the elements of tennis, badminton, and ping-pong. It is reported to be increasingly popular in the United States (US), particularly among older adults. There is limited published information on pickleball-related injuries, including those involving the lower extremity.

Pickleball has exploded in popularity the past decade or so. Especially with seniors! More than 3 million people of all ages in the United States alone play and that number is growing by 10% every year, according to Athletic Business. The allure of the sport, especially for seniors, is that there isn’t a lot of running, but there is a lot of competition.

Have you ever asked yourself this simple question: why do we measure and analyze gait? Overall, the answers will revolve around the same ideas: to gauge the functional status of a person; to follow-up the natural history of a disease; to determine immediate or long-term treatment requirement and effects.

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
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.

More popular than ever, skiing remains a complex sport with a high risk of injury. Here we detail some of the pertinent data. Skiing, a sport that has been around since Cro-Magnon man, is among the most popular winter sports in the United States. There were nearly 15 million skiers in the US in 2017 alone.

The authors present four cases of complex lower extremity reconstruction involving segmental bone loss and deformity – failed total ankle arthroplasty, talus avascular necrosis, ballistic trauma, and nonunion of a tibial osteotomy.

Foot drop, a complex condition that can have a significant impact on independent ambulation, can have many causes. Treatment options vary by cause. These authors provide a review of the condition from etiology through treatment. Foot drop (also known as steppage gait) is an inability to lift the forefoot due to the weakness of dorsiflexors of the foot. This, in turn, can lead to an unsafe antalgic gait, potentially resulting in falls.

Researchers from Korea have developed a new type of AFO that uses neoprene and a novel wire configuration for use with foot drop after stroke. Foot drop can be a sequela of stroke. An ankle–foot orthosis (AFO) is the most widely used method to prevent foot drop in patients with stroke, and is used during weight-bearing training of the limb on the affected side or when there is ankle spasticity or deformity.

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. Continue reading
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).

This 2-part series examines the current state of peripheral artery disease. This article focuses on disease burden, risk factors, and clinical presentation. Part 2, which will appear next month, will examine current recommendations for diagnosis and treatment.

With existing knowledge, much of the cardiovascular risk burden of peripheral artery disease (PAD) is preventable. PAD is a common atherosclerotic syndrome that is estimated to affect 12.5 million Americans and 237 million people worldwide.1 One in five Americans over the age of 65 has PAD.2 Based on national treatment patterns, more than half of all patients with PAD do not know they have it.

Reported incidence rates for ankle sprains range from 15% to 45%. This study looked at self-reported ankle instability in regional European football players and found that age and injury repetition as well as exposure time and position on the field were associated with instability rates, suggesting the need for specific prevention strategies.
