Effect of environmental setting on mobility methods of children with cerebral palsy.

The aim of this study was to: (1) describe the usual mobility methods of children with cerebral palsy (CP) at home, school, and outdoors or in the community and (2) examine whether children with CP are more dependent on adult assistance for mobility in ...

Horse-race model simulations of the stop-signal procedure.

In the stop-signal paradigm, subjects perform a standard two-choice reaction task in which, occasionally and unpredictably, a stop-signal is presented requiring the inhibition of the response to the choice signal. The stop-signal paradigm has been ...

Cortical and cerebellar activity of the human brain during imagined and executed unimanual and bimanual action sequences: a functional MRI study.

The neural (blood oxygenation level dependent) correlates of executed and imagined finger sequences, both unimanual and bimanual, were studied in adult right-handed volunteers using functional magnetic resonance imaging (fMRI) of the entire brain. The ...

Deep brain stimulation of the subthalamic nucleus: effectiveness in advanced Parkinsons disease patients previously reliant on apomorphine.

OBJECTIVES: To assess the efficacy of bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in patients with advanced Parkinsons disease previously reliant on apomorphine as their main antiparkinsonian medication. METHODS: Seven patients with ...

Pharmacologically modulated fMRI--cortical responsiveness to levodopa in drug-naive hemiparkinsonian patients.

According to the basal ganglia-thalamocortical circuit model, dopamine depletion in the nigrostriatal system leads to hypoactivation in the supplementary motor area (SMA) and the primary motor cortex (M1) in Parkinsons disease. This functional cortical ...

Gross motor function classification system: preliminary study for Japanese children.

OBJECTIVE: The purpose of the study was to produce a version of the Gross Motor Function Classification System with the same construct as the original one that would be applicable to Japanese children with cerebral palsy. DESIGN: The reliability studies ...

Functional properties of brain areas associated with motor execution and imagery.

Imagining motor acts is a cognitive task that engages parts of the executive motor system. While motor imagery has been intensively studied using neuroimaging techniques, most studies lack behavioral observations. Here, we used functional MRI to compare ...

The aging hand.

Hand function decreases with age in both men and women, especially after the age of 65 years. A review is presented of anatomical and physiological changes in the aging hand. The age-related changes in prehension patterns (grip and pinch strength) and ...

Increasing the distance of an external focus of attention enhances learning.

Previous studies (e.g., Wulf, Höss, & Prinz, 1998) have shown that motor learning can be enhanced by directing performers attention to the effects of their movements ("external focus"), rather than to the body movements producing the effect ("internal ...

The reach-to-grasp movement in children with autism spectrum disorder.

Autism is associated with a wide and complex array of neurobehavioural symptoms. Examination of the motor system offers a particularly appealing method for studying autism by providing information about this syndrome that is relatively immune to ...
