As physiological signals that are closely related to human motion, surface electromyography
(sEMG) signals have been widely used in human-robot interaction systems (HRISs). Some …

The article offers a way to unite three recent developments in the field of motor control and
coordination:(1) The notion of synergies is introduced based on the principle of motor …

It has been shown that humans are able to selectively control the endpoint impedance of
their arms when moving in an unstable environment. However, directional instability was …

Human partners working on a target acquisition task perform faster than do individuals on
the same task, even though the partners consider each other to be an impediment. We …

The nervous system controls the behavior of complex kinematically redundant
biomechanical systems. How it computes appropriate commands to generate movements is …

A synthesis of biomechanics and neural control that draws on recent advances in robotics to
address control problems solved by the human sensorimotor system. This book proposes a …

The perturbation method has been used to measure stiffness of the human arm with a
manipulator. Results are averages of stiffness during short perturbation intervals (< 0.4 s) …

There is ample evidence that humans are able to control the endpoint impedance of their
arms in response to active destabilizing force fields. However, such fields are uncommon in …

Coactivation of antagonist muscles is readily observed early in motor learning, in
interactions with unstable mechanical environments and in motor system pathologies. Here …

The mechanical properties of the human arm are regulated to maintain stability across many
tasks. The static mechanics of the arm can be characterized by estimates of endpoint …
