Falls precipitated by slipping are listed among the leading causes of injuries. The biomechanical analysis of such events is a necessary component of the slips/falls prevention research. One of the challenges of biomechanical studies is reproducing the unexpected nature of real-life slipping accidents. Thus, the goal of this study was to quantify changes in gait biomechanics when subjects antic...

In human beings, the muscles of the sole of the foot are known to exhibit variations. During routine cadaveric dissection, an anomalous attachment of the flexor digiti minimi muscle was observed on both sides of a 55 year male cadaver. The flexor digiti minimi muscle had its usual origin from the plantar surface of base of the fifth metatarsal bone and the sheath of the peroneus longus muscle a...

This paper describes the design of an ankle-foot robotic prosthesis controllable in the sagittal and frontal planes. The prosthesis was designed to meet the mechanical characteristics of the human ankle including power, range of motion, and weight. To transfer the power from the motors and gearboxes to the ankle-foot mechanism, a Bowden cable system was used. The Bowden cable allows for optimal...

INTRODUCTION Centrifuge-induced artificial gravity (AG) with exercise is a promising comprehensive countermeasure against the physiological de-conditioning that results from exposure to weightlessness. However, body movements onboard a rotating centrifuge are affected by both the gravity gradient and Coriolis accelerations. The effect of centrifugation on squat exercise biomechanics was investi...

Heel pain is a very common foot disease that may cause significant discomfort and disability. Biomechanic factors are the most etiology can induce mild to moderate chronic heel pain. Common conditions related with includes: plantar fasciitis, calcaneal spur, sever's disease, Achilles tendinopathy, bursitis. Location of guide proper diagnosis for particular variety This review presents current s...

We previously developed an ankle-foot prosthesis emulator with exceptional versatility [1]. It is lightweight, capable of producing large torque and power, and can quickly change behaviors [2]. However, it cannot fully address the needs of trans-femoral amputees. In the commercial market there are many active knees such as the Ottobock C-leg and Össur Power Knee. These are successful products, ...

Background Over the past two decades finite element (FE) analysis has become a popular tool for researchers looking to simulate the biomechanics of the foot in people with diabetes. The ultimate aims of these simulations have been to improve understanding of the complicated nature of mechanical loading and to inform interventions designed to prevent plantar ulceration. This review is intended t...

Foot and ankle complaints are commonly encountered in orthopedic practice. Midfoot arthritis has the potential to cause a significant amount of pain and disability. A variety of conditions can cause or lead to midfoot arthritis. Treatment consists of either conservative management or surgical arthrodesis of the painful joints. In this article, we review the midfoot (its basic anatomy and biomec...

PURPOSE To determine prevalence of heel strike in a midsize city marathon, if there is an association between foot-strike classification and race performance, and if there is an association between foot-strike classification and gender. METHODS Foot-strike classification (forefoot, midfoot, heel, or split strike), gender, and rank (position in race) were recorded at the 8.1-km mark for 2112 r...
