Recent Advances in the Application of Blood Flow Restriction for Health and Performance
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.

Pregnancy Part 1: Is Walking Adequate Fitness During Pregnancy?
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.

Gait and Balance Academy: How Do We Use Gait Analysis to Measure Walking Consistency?
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.

Foot Drop: A Primer
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.

Expanding Our Understanding of Chronic Ankle Instability
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

Functional Ankle Instability Prevalence and Associated Risk Factors in Male Football Players
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.

The Utility of External Fixation for Midfoot Charcot Neuroarthropathy
When conservative therapies fail, surgical reconstruction of the foot is often required to restore function, heal ulcerations, and decrease risk of amputation in patients with CN. External fixation remains a reliable method, with plenty of advantages.

Using The “Reformer,” “Wunda Chair,” and “foot Corrector”: The Pilates Method Enhances Alignment and Core Awareness
A trained Pilates professional in a fully equipped studio can help your patient make significant improvement in strength and flexibility by addressing postural habits and alignment problems. Joseph Hubertus Pilates began development of his method – a body–mind approach to exercise –in the early 1920s. As a child, Pilates suffered from asthma, rickets, and rheumatic fever.

White Paper: Foot Pronation
Over the past decades, pronation has been discussed as a potential risk factor for injuries or as the mechanism behind impact damping. However, little is understood about pronation. The objectives of this paper were to (a) define and differentiate between the terms of pronation and eversion, (b & c) underline the importance and problematic aspects of pronation.

Overuse Injuries in Sports Aren’t Wholly Preventable. But They Are Reducible
Empower athletes and work in partnership with them to reduce their risk and severity of overuse injury and keep them at the level of performance they want. Getting better at any sport, at any level, takes practice, commitment—and repetition. Basketball players shoot jump shot after jump shot, soccer players drill footwork, and cross-country athletes log seemingly endless miles.

Pregnancy Changes the Body: Here’s What That Means for Gait, Balance, and Falls
About a quarter of women fall during pregnancy and 10% fall more than once. Understanding the biomechanical changes of this transitional period may help researchers find ways to prevent such falls. When Robert Catena’s wife was pregnant and working at a restaurant, she fell. It was scary, he says, but everything was ok.

Vexing Question: How Soon Should Patients Drive After Lower-Extremity Surgery?
The answer doesn’t come easily; official guidelines are lacking. Ultimately, patients bear responsibility for the decision, but you can still offer them valuable advice for keeping safe. “Doctor, when can I start driving again?” That’s a common question patients ask when they’re headed for lower-extremity surgery. But it’s not always an easy one to answer.
