background: joint position sense (jps) is comprised of sensory input from several sources, including skin, joint capsule/ligaments, and muscular receptors. if the muscle receptors play a leading role in detecting joint position awareness, then muscle fatigue might yield a declination in jps. the aim of this study was to evaluate if a sustained fatiguing contraction of the tibialis anterior (ank...

We often see painful ankle joint destruction with painful hindfoot valgus deformity in rheumatoid arthritis. Our policy in such cases has been to first correct the hindfoot deformity in the subtalar joint with fusion, but then ankle joint pain has been observed. Two women with rheumatoid arthritis underwent correction and fusion surgery for hindfoot valgus deformity. They had been using wheelch...

The goal of this study was to describe the movement patterns of the ankle joint whilst standing on one leg. Ten healthy adult females (age 24 +/- 5.3 years) performed a one-legged standing task with eyes closed. Force platform recordings and video analyses were used to describe the kinematic and kinetic characteristics of the ankle joint during this task. A rocking movement of the foot (heel in...

objectives: this paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. the objective was to control the ankle hysteresis at slow and normal walking speeds. methods: inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for ad...

Ankle joint distraction has been shown to be a viable alternative to ankle arthrodesis or ankle replacement. The authors' approach to ankle joint preservation includes articulated ankle joint distraction, resection of blocking osteophytes, release of muscle and joint contractures, and realignment osseous ankle procedures. In a previous study that used this technique, 78% of patients maintained ...

Introduction The ankle joint is the most injured joint during sports participation [1]. Ankle orthoses have been shown to be effective in reducing ankle inversion injuries and are often prescribed for rehabilitation and prevention of lateral ankle sprains. Efficacy of ankle orthoses is often assessed by comparing reduction of passive inversion ROM as well as ankle kinematics between braced and ...
