The case for and against muscle synergies
A long standing goal in motor control is to determine the fundamental output controlled by
the CNS: does the CNS control the activation of individual motor units, individual muscles …

[HTML][HTML] Human upright posture control models based on multisensory inputs; in fast and slow dynamics
Posture control to maintain an upright stance is one of the most important and basic
requirements in the daily life of humans. The sensory inputs involved in posture control …

Exoskeletons need to react faster than physiological responses to improve standing balance
Maintaining balance throughout daily activities is challenging because of the unstable
nature of the human body. For instance, a person's delayed reaction times limit their ability to …

Common muscle synergies for balance and walking
Little is known about the integration of neural mechanisms for balance and locomotion.
Muscle synergies have been studied independently in standing balance and walking, but …

Neuromechanics of muscle synergies for posture and movement
Recent research suggests that the nervous system controls muscles by activating flexible
combinations of muscle synergies to produce a wide repertoire of movements. Muscle …

Subject-specific muscle synergies in human balance control are consistent across different biomechanical contexts
The musculoskeletal redundancy of the body provides multiple solutions for performing
motor tasks. We have proposed that the nervous system solves this unconstrained problem …

[PDF][PDF] Contact-invariant optimization for hand manipulation
We present a method for automatic synthesis of dexterous hand movements, given only high-
level goals specifying what should happen to the object being manipulated. Results are …

Intermittent control: a computational theory of human control
The paradigm of continuous control using internal models has advanced understanding of
human motor control. However, this paradigm ignores some aspects of human control …

Muscle coordination is habitual rather than optimal
When sharing load among multiple muscles, humans appear to select an optimal pattern of
activation that minimizes costs such as the effort or variability of movement. How the nervous …

Do humans optimally exploit redundancy to control step variability in walking?
It is widely accepted that humans and animals minimize energetic cost while walking. While
such principles predict average behavior, they do not explain the variability observed in …
