Impairments in dexterous upper limb function are a significant cause of disability following
stroke. While the physiological basis of movement deficits consequent to a lesion in the …

The impact of stroke on motor functioning is analyzed at different levels.'Impairment'denotes
the loss of basic characteristics of voluntary movement.'Activity limitation'denotes the loss of …

The rehabilitation of motor deficits following stroke relies on both sensorimotor and cognitive
abilities, thereby involving large‐scale brain networks. However, few studies have …

Synergies are thought to be the building blocks of vertebrate movements. The inability to
execute synergies in properly timed and graded fashion precludes adequate functional …

Cortical and subcortical plastic reorganization occurs in the course of motor recovery after
stroke. It is largely accepted that plasticity of ipsilesional motor cortex primarily contributes to …

Following hemiparetic stroke, precise, individuated control of single joints is often replaced
by highly stereotyped patterns of multi-joint movement, or abnormal limb synergies, which …

The brain has an intrinsic capacity to compensate for structural damage through
reorganizing of surviving networks. These processes are fundamental for recovery of …

Motor recovery following stroke is believed to necessitate alteration in functional connectivity
between cortex and muscle. Cortico-muscular coherence has been proposed as a potential …

Motor dysfunction is a major consequence after stroke and it is generally believed that the
loss of motor ability is caused by the impairments in neural network that controls movement …

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 …
