We sought to gain insight into age-related muscular limitations that may restrict the uphill walking ability of old adults. We hypothesized that: (1) old adults would exhibit smaller peak ankle joint kinetics and larger peak hip joint kinetics than young adults during both level and uphill walking and (2) these age-related differences in ankle and hip joint kinetics would be greatest during uph...

Objective: The aim of this study was to investigate the relationship between isokinetic relative torques of hip, knee and ankle joints and the height of guide leg jump in young men. Methods: 27 college male athletes with mean age of 25±3.5 years, height 178.5±7.8 cm and weight of 75.7±10.7 kg voluntarily participated in this study. Isokinetic torque of hip, knee and ankl...

in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...

The ankle joint is part of a biomechanical hindfoot complex. Approximately 1% of the world's adult population is affected by ankle osteoarthritis (AO). Trauma is the primary cause of ankle OA, often resulting in varus or valgus deformities. Only 50% of patients with end-stage ankle OA have a normal hindfoot alignment. The biomechanics and morphology of the arthritic valgus ankle is reviewed in ...

Objective Running is known as one of the most popular sports for which there is no time and space limit. Recently, due to lifestyle changes, the use of treadmills for walking and running has increased. However, the biomechanical differences in coordination between running on a treadmill at different speeds have not been sufficiently addressed. The aim of this study was to investigate the effect...

OBJECTIVE To apply the dual Euler angles method to investigate the passive motion characteristics of the human ankle joint complex. DESIGN Three-dimensional kinematic data of the ankle joint complex was collected from 10 knee-below foot cadaver specimens. BACKGROUND Besides the Euler angles and screw axis methods, the dual Euler angles method has been proposed as an alternative approach to ...

UNLABELLED Painful conditions and limited dorsal flexion of the ankle, which are the result of the friction of joint tissues and also the cause and the effect of altered joint biomechanics, are called ankle impingement syndromes. Post-traumatic ankle injures, like an ankle sprains or ankle fractures, are the main causes of impingement lesions, which result in chronic ankle pain. PURPOSE To ev...
