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 ...
Impact of muscle power and force on gait speed in disabled older men and women
BACKGROUND: The purpose of this study was to explore the relationship between muscle power output at different external resistances and...
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 dir...
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 ...
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 sing...
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 al...
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...
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. W...
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 re...
