The arm-swing motion is important for coordinated lower limb movement during a fast sprint and is composed of three-dimensional scapulothoracic and glenohumeral joint motion. Here, we aimed to clarify the role of the scapula during the initiation of a sprint running when sprinter run with high horizontal acceleration. Ten sports-active students participated in four 5-m dashes, with scapular con...

Background The use of multi-segment foot models is becoming increasingly popular during clinical gait analysis. While numerous studies have established the repeatability of these models, the accuracy is more difficult to determine since measuring motion of the bones is a challenging task. One assumption influencing model accuracy is that surface markers can be placed precisely over palpated, bo...

Background Gold standard for the management of diabetic foot neuropathic ulcers is the irremovable total contact cast, however evidence of equal clinical effectiveness was proved for the removable walker OPTIMA DIAB [1]. Priority of this healing treatment is the offloading of the ulcerated foot area; however, the healing process may last for months, and eventual changes in gait biomechanics may...

The aim of this study was to compare the plantar pressures and forces recorded from both feet of two groups of javelin throwers of different performance levels, in order to investigate differences between skill levels. The study was carried out using an EMED insole system on a Tartan javelin runway at the University of Innsbruck, Austria. Most of the differences (at p < .01) between the two gro...

Contact mechanics plays an important role in the design, performance analysis, simulation, and control of legged robots. The Hunt–Crossley model and the Coulomb friction model are often used as black-box models with limited consideration of the properties of the terrain and the feet. This paper analyzes the foot–terrain interaction based on the knowledge of terramechanics and reveals the relati...

In industrial or surgical settings, to achieve many tasks successfully, at least two people are needed. To this end, robotic assistance could be used enable a single person perform such alone, with the help of robots through direct, shared, autonomous control. We interested in four-arm manipulation scenarios, where both feet control arms via bi-pedal haptic interfaces. The complement biological...

BACKGROUND Foot musculoskeletal deficits are seldom addressed by preventive medicine despite their high prevalence in patients with diabetic polyneuropathy. AIM To investigate the effects of strengthening, stretching, and functional training on foot rollover process during gait. METHODS A two-arm parallel-group randomized controlled trial with a blinded assessor was designed. Fifty-five pat...

External rotation of the foot associated with mid-foot break is a commonly observed gait abnormality in diplegic CP patients. Previous studies have shown a correlation between equinus and internal hip rotation in hemiplegic patients. This study aimed to determine if there was a correlation between the amount of transverse plane rotation in diplegic CP patients using kinematic data from standard...
