Evidence suggests that the nervous system controls motor tasks using a low-dimensional
modular organization of muscle activation. However, it is not clear if such an organization …

The intact nervous system has an exquisite ability to modulate the activity of multiple
muscles acting at one or more joints to produce an enormous range of actions. Seemingly …

Following stroke, people commonly demonstrate locomotor impairments including reduced
walking speed and spatiotemporal asymmetry. Rehabilitation programs have been effective …

Background Powered lower limb prostheses could be more functional if they had access to
feedforward control signals from the user's nervous system. Myoelectric signals are one …

It is a fantastic time for the field of robotic exoskeletons. Recent advances in actuators,
sensors, materials, batteries, and computer processors have given new hope to creating the …

Auditory feedback may provide the nervous system with valuable temporal (eg, footstep
sounds) and spatial (eg, external reference sounds) information that can assist in the control …

Locomotor adaptation in humans is not well understood. To provide insight into the neural
reorganization that occurs following a significant disruption to one's learned neuromuscular …

Objective To evaluate the response of bone to 2 anabolic stimuli, teriparatide and
mechanical loading, in subjects with spinal cord injury. Design A pilot study, 1 group, pretest …

Human walking must be flexible enough to accommodate many contexts and goals. One
form of this flexibility is locomotor adaptation: a practice-dependent alteration to walking …

Human locomotion is a rhythmic task in which patterns of muscle activity are modulated by
state-dependent feedback to accommodate perturbations. Two popular theories have been …
