Here, we developed a mobile exoskeleton that can provide plantarflexion torque assistance at the ankle. The actuation system is switchable between a single- and dual-motor ones to adapt to different ...

Inspired by the bionic characteristics of ankle and calf skeletal muscles, a novel ankle-foot prosthesis (AFP) with variable stiffness mechanisms (VSMs) is proposed to assist transtibial amputees to ...

Fractures of the posterior process of the talus occur by direct impingement of the posterolateral tubercle on the posterior tibial plafond with forced plantarflexion of the ankle or as a bony ...

Shifting between these two moments requires the Achilles to transition between being flexible (allowing for lots of plantarflexion) then elastic and stiff (to drive the athlete forward).

Strength training does two important things at once: it improves performance and (perhaps most important) reduces the risk of injury. Stronger muscles, and more reliable joints, t ...
