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.

Needed, Proposed, Designed: An Injury Assessment and Prevention Program for Collegiate Women’s Basketball
Why are female basketball players increasingly at risk of lower-extremity injury? How should an injury prevention program for them be devised and implemented? The authors undertook a team study to find the answers. Knee injuries account for 10% to 25% of sports-related injuries.

Vaping: How Smoking E-Cigarettes Affects Physiology and Athletic Performance
Editor’s Note: As of press time, the US Centers for Disease Control has reported 1299 cases of e-cigarette- or vaping-associated lung injury (EVALI) and issued interim guidance to assist with assessment, evaluation, management, and followup. The cases have been reported in 49 states and the Distric of Columbia, with 26 deaths reported across 21 states.

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.

Diabetes, Its Impact, and Protection of the Diabetic Foot
Offloading is key to preventing small concerns from becoming life-threatening, but adherence remains less than optimal. The not-so-secret truth: diabetes and its precursor, prediabetes, have reached epidemic status in the United States: More than 100 million Americans are living with the disease.

Slip, Trip, Stumble, Fall: An Overview of Falls in the Elderly and How to Prevent Them
When 88-year-old Doris fell getting out of the bathtub late on a Tuesday in the apartment she shared with her 90-year-old husband of 65 years, the ambulance took her to the hospital. As suspected, she had broken her right hip, which was surgically corrected Wednesday morning…

Stress Fractures Of the Foot in Football
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…

Hamstring: Trends in preventing and treating hamstring-strain injuries
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…

Limb Salvage or Amputation of the Diabetic Foot?
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).

What role for eccentric exercises in conservative treatment of achilles tendinopathy
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?

Assessing Limb Length Discrepancy
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.

Patellofemoral pain: More activity means more pain — and then less activity?
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…

BRAINS, SPRAINS, AND CHRONIC PAIN: Concussion consequences may include osteoarthritis
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.

Focus on biomechanics helps treat claudication
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.

Assessing runners’ gait using wearable sensors
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.

When a longtime patient dies: How clinicians cope
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.

HANDLE WITH CARE: How sports equipment affects biomechanics and injury risk
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.

Implications of high ankle sprains in college athletes
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 management tactics for hallux limitus
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.

Return-to-play concerns following Achilles tears
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.
