Positive force feedback in human walking.
The objective of this study was to determine if load receptors contribute to the afferent-mediated enhancement of ankle extensor muscle activity during the late stance phase of the step cycle. Plantar flexion perturbations were presented in late stance while able-bodied human subjects walked on a treadmill that was declined by 4%, inclined by 4% or held level. The plantar flexion perturbation p...
متن کاملDevelopment of a human walking model comprising springs and positive force feedback to generate stable gait
Biomechanics is a very important field of study when one considers the importance that motion, such as walking, has in our everyday life. Although we perform tasks such as running and climbing stairs in an automatic way, without even thinking of it, these tasks are extremely complex from a mechanical and biological point of view. Nowadays, the progression of science towards the understanding of...
متن کاملPositive force feedback in bouncing gaits?
During bouncing gaits (running, hopping, trotting), passive compliant structures (e.g. tendons, ligaments) store and release part of the stride energy. Here, active muscles must provide the required force to withstand the developing tendon strain and to compensate for the inevitable energy losses. This requires an appropriate control of muscle activation. In this study, for hopping, the potenti...
متن کاملPositive force feedback control of muscles.
This study was prompted by recent evidence for the existence of positive force feedback in feline locomotor control. Our aim was to establish some basic properties of positive force feedback in relation to load compensation, stability, intrinsic muscle properties, and interaction with displacement feedback. In human subjects, muscles acting about the wrist and ankle were activated by feedback-c...
