In this presentation, we will look at some of the great paradigms of injury prevention that have underpinned the running shoe industry for more than 40 years: motion control and cushioning. Do these paradigms stand up to scientific scrutiny, and if not, where else should we be looking?

We typically lose proprioception as we age, which can negatively affect balance. But why do we lose proprioception simply because we age? Proprioception was originally defined as “the perception of joint and body movement as well as position of the body, or body segments, in space.” At present, proprioception can be...

The goal of walking 10,000 steps per day is not rooted in science. Rather, it came from a clever Japanese marketing campaign in 1964, for a pedometer called the Manpo-kei: “man” meaning 10,000, “po” meaning steps, and “kei” meaning meter. Despite the origin, this number became a benchmark to achieve while walking...
Dancing is a special competitive sport with dancers performing moves in both open and closed kinetic chains…but is training focused on injury prevention? Is it time for a shoe re-design? Dancing may be termed a special competitive sport and dancers perform an activity in both open and closed kinetic chains.

There are millions of pet dogs in the United States (US), and thousands of people are treated at US hospital emergency departments (EDs) each year for dog bites. Approximately 20-25% of these dog bites affect the lower extremity. The objective of this study was to characterize dog bites of the lower extremity treated...

When a cartilage surface is damaged, it often occurs via a rotational movement with a force coming from the side or as a direct force. In this type of injury, the forces affect the different layers in the cartilage so that the greatest weakness lies in the layer between the calcified cartilage and other cartilage.
In a study of both trail and road runners, researchers from Belgium sought to investigate the risk factors for running-related injuries (RRIs). They conducted an online survey of 3,669 injured and noninjured runners. Injury was defined as pain of various kinds, without attention to its consequences on running practice.
Falls are a leading cause of injury, hospitalization, and death among older adults due to a variety of factors, but 2 are key: 1) Changes to the medio-lateral margin of stability, pace, and base of support, which typically occur as part of the aging process; and 2) Increased use of multiple medications for a variety of chronic illnesses...
Most of older adults’ falls are related to inefficient balance recovery after an unexpected loss of balance, i.e., postural perturbation. Effective balance recovery responses are crucial to prevent falls. Due to the considerable consequences of lateral falls and the high incidence of falls when walking, this study aimed to...
For many years, knee-ankle-foot orthosis (KAFO) therapy to improve functional mobility and activities of daily living (ADL) was considered to be effective for patients with stroke. However, evidence regarding the efficacy of KAFO use post-stroke is unclear, due to a lack of published high-quality studies.
Biomechanics are foundational to podiatry, physiotherapy, and the study of orthotics and prosthetics. Here we provide an excerpt from the author’s recently released Book 1 of the 4-part series, Practical Biomechanics for the Podiatrist.

Is there a link between diabetes and chronic venous insufficiency (CVI)? Well, let’s just say that relationship is “complicated.” While diabetes may not directly cause venous insufficiency, it does have an effect on the tissues of the lower extremities. It has been documented that glycosylated hemoglobin is damaging to...

Prosthetic manufacturer and patient care provider Ottobock, Duderstadt, Germany, has recently agreed to acquire Pace Rehabilitation, one of the United Kingdom’s (UK’s) independent providers of prosthetic and rehabilitation services for people who have sustained a serious limb injury.
Researchers from the Massachusetts Institute of Technology (MIT) and elsewhere demonstrated an in-home device that can monitor a patient’s movement and gait speed, which can be used to evaluate Parkinson’s severity, the progression of the disease, and the patient’s response to medication.
A team from the University of Notre Dame’s Robotics, Optimization and Assistive Mobility (ROAM) lab has tested 3 different control mechanisms designed to advance the human-machine interface of a powered prosthetic ankle. While current lower limb prostheses can be given a motor assist, the team is advancing the
Using a novel fabrication process, researchers from the Massachusetts Institute of Technology (MIT) have produced smart textiles that snugly conform to the body so they can sense the wearer’s posture and recognize its wearer’s activities, like walking, running, and jumping. By incorporating a special type of plastic yarn and...
Sprint kinematics have been linked to hamstring injury and performance. This study aimed to examine if a specific 6-week multimodal intervention, combining lumbopelvic control and unning technique exercises, induced changes in pelvis and lower-limb kinematics at maximal speed and improved sprint performance.
