Spatial representation of predictive motor learning.

A key feature of skilled motor behavior is the ability of the CNS to predict the consequences of its actions. Such prediction occurs when one hand pulls on an object held in the other hand; the restraining hand generates an anticipatory increase in grip ...

Measurement reliability of functional tasks for persons who self-propel a manual wheelchair.

OBJECTIVE: To evaluate the reliability of 4 functional tasks relevant to wheelchair seating. DESIGN: Within-subject and between-rater comparisons. SETTING: Rehabilitation center in Canada. PARTICIPANTS: Two separate convenience samples of 10 male ...

Task goals and change in dynamical degrees of freedom with motor learning.

In this article, the authors examined the hypothesis that the direction of the change (increase or decrease) in the dynamical degrees of freedom (dimension) regulated as a function of motor learning is task-dependent. Adult participants learned 1 of 2 ...

Neocortical mechanisms in motor learning.

The ability to learn novel motor skills has fundamental importance for adaptive behavior. Neocortical mechanisms support human motor skill learning, from simple practice to adaptation and arbitrary sensory-motor associations. Behavioral and neural ...

Improving the Glasgow Coma Scale score: motor score alone is a better predictor.

BACKGROUND: The Glasgow Coma Scale (GCS) has served as an assessment tool in head trauma and as a measure of physiologic derangement in outcome models (e.g., TRISS and Acute Physiology and Chronic Health Evaluation), but it has not been rigorously ...

Ipsilateral cortical activation during finger sequences of increasing complexity: representation of movement difficulty or memory load?

OBJECTIVE: To investigate, if increasing ipsilateral cortical activation during sequential finger movements of increasing complexity relates to the difficulty of transitions (sequence complexity) or to increasing motor memory load (sequence length). ...

Ecology of development in children with brain impairment.

BACKGROUND: Many children with brain impairments develop well in spite of negative risk factors or prognoses. Most follow-up and review studies do not show uncontroversial effects of particular physiotherapy or activation programmes. Evidence is ...

Sex differences in lateralisation of fine manual skills in children.

One hundred and twelve children (55 boys and 57 girls) were tested using two tasks taken from the Movement Assessment Battery for Children. The girls had a larger between-hands asymmetry than boys on the threading nuts on bolt task, thus indicating they ...

Pre-frontal executive committee for perception, working memory, attention, long-term memory, motor control, and thinking: a tutorial review.

As an explicit organizing metaphor, memory aid, and conceptual framework, the prefrontal cortex may be viewed as a five-member Executive Committee, as the prefrontal-control extensions of five sub-and-posterior-cortical systems: (1) the Perceiver ...

Intravenous amantadine sulphate application improves the performance of complex but not simple motor tasks in patients with Parkinsons disease.

Intravenous application of amantadine sulphate induces a rapid improvement of motor symptoms in Parkinsons disease (PD), but there are no trials on the efficacy of this compound on bradykinesia, rigidity and tremor in detail in combination with ...
