Using electromyogram (EMG) signals to control upper-limb prostheses is an important
clinical option, offering a person with amputation autonomy of control by contracting residual …

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 …

Muscle synergies are neural coordinative structures that function to alleviate the
computational burden associated with the control of movement and posture. In this …

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 …

Optimal control theory and its more recent extension, optimal feedback control theory,
provide valuable insights into the flexible and task-dependent control of movements. Here …

Previous studies in neurologically intact subjects have shown that motor coordination can be
described by task-dependent combinations of a few muscle synergies, defined here as a …

Several efforts have been carried out to enhance dexterous hand prosthesis control by
impaired individuals. Choosing which voluntary signal to use for control purposes is a critical …

Highlights•Motor primitive analyses can capture kinematic and muscle level organization of
movement across reflex, locomotor and novel skilled tasks.•Kinematic structure and a …

The term 'synergy'–from the Greek synergia–means 'working together'. The concept of
multiple elements working together towards a common goal has been extensively used in …

Production of voluntary movements relies critically on the functional integration of several
motor cortical areas, such as the primary motor cortex, and the spinal circuitries …
