Prevention of falls in the elderly trial (PROFET): a randomised controlled trial

BACKGROUND: Falls in elderly people are a common presenting complaint to accident and emergency departments. Current practice commonly focuses on the injury, with little systematic assessment of the underlying weiter...

Neuromechanical adaptation to hopping with an elastic ankle-foot orthosis

When humans hop or run on different surfaces, they adjust their effective leg stiffness to offset changes in surface stiffness. As a result, the overall stiffness of the leg-surface series combination remains i weiter...

Neuromuscular changes for hopping on a range of damped surfaces

Humans hopping and running on elastic and damped surfaces maintain similar center-of-mass dynamics by adjusting stance leg mechanics. We tested the hypothesis that the leg transitions from acting like an energy weiter...

Passive dynamics change leg mechanics for an unexpected surface during human hopping

Humans running and hopping maintain similar center-of-mass motions, despite large changes in surface stiffness and damping. The goal of this study was to determine the contributions of anticipation and reaction weiter...

Runners adjust leg stiffness for their first step on a new running surface

Human runners adjust the stiffness of their stance leg to accommodate surface stiffness during steady state running. This adjustment allows runners to maintain similar center of mass movement (e.g., ground cont weiter...

Running in the real world: adjusting leg stiffness for different surfaces

A running animal coordinates the actions of many muscles, tendons, and ligaments in its leg so that the overall leg behaves like a single mechanical spring during ground contact. Experimental observations have weiter...

Running springs: speed and animal size

Trotting and hopping animals use muscles, tendons and ligaments to store and return elastic energy as they bounce along the ground. We examine how the musculoskeletal spring system operates at different speeds weiter...

Soleus H-reflex gain in humans walking and running under simulated reduced gravity

The Hoffmann (H-) reflex is an electrical analogue of the monosynaptic stretch reflex, elicited by bypassing the muscle spindle and directly stimulating the afferent nerve. Studying H-reflex modulation provides weiter...
