Use of an ecologically based program for teaching motor skills in a naturalistic setting to individuals with disabilities.

The purpose of this action study was to apply an ecological program for teaching motor skills to individuals with disabilities in naturalistic settings. The program was developed based on an ecological survey. Participants were 22 individuals with ...

L-dopa effects on preprogramming and control activity in a skilled motor act in Parkinsons disease.

OBJECTIVES: The authors investigated whether preprogramming (Bereitschaftspotential, BP) and control activity (skilled performance positivity, SPP) in a bimanual, sequential skilled performance task (SPT) is sensitive to L-dopa administration in ...

Dynamic cortical and subcortical networks in learning and delayed recall of timed motor sequences.

We used positron emission tomography to examine learning and retention of timed motor sequences. Subjects were scanned during learning (LRN) and baseline (ISO) on 3 d: day 1, after 5 d of practice (day 5) and after a 4 week delay (recall). Blood flow was ...

Rational imitation in preverbal infants.

Here we show that if an adult demonstrates a new way to execute a task to a group of infants aged 14 months, the children will use this action to achieve the same goal only if they consider it to be the most rational alternative. Our results indicate ...

Early consolidation in human primary motor cortex.

Behavioural studies indicate that a newly acquired motor skill is rapidly consolidated from an initially unstable state to a more stable state, whereas neuroimaging studies demonstrate that the brain engages new regions for performance of the task as a ...

Building anticipatory postural adjustment during childhood: a kinematic and electromyographic analysis of unloading in children from 4 to 8 years of age.

The present study addressed the question of how do anticipatory postural adjustments (APA) develop during childhood, in the range from 4 to 8 years, during a bimanual load-lifting task. This task required maintaining the stabilisation of the forearm ...

Age at menarche in competitive figure skaters: variation by competency and discipline.

We estimated age at menarche in a cross-sectional sample of 159 competitive figure skaters aged 11-22 years. The sample represented three standards (test stream, pre-elite, elite) and three disciplines (free skaters, pair skaters, dancers). The status ...

Deliberate imagery practice: the development of imagery skills in competitive athletes.

The aim of this study was to examine mental imagery within the context of the deliberate practice framework. Altogether, 159 athletes from one of three different competitive standards (recreational, provincial and national) completed the Deliberate ...

Dynamics of coordination within elite rowing crews: evidence from force pattern analysis.

For a rowing crew to be successful, the movements of the rowers need to be well coordinated. Because rowers show individual force patterns, they have to adapt their movements when rowing as a crew. In this exploratory study, these hypothesized changes in ...

Adaptation of postural control to perturbations--a process that initiates long-term motor memory.

The objective was to investigate postural control adaptation during daily repeated posturography with vibratory calf stimulation. The posturography was performed with eyes open and closed daily for 5 days and after 90 days on 12 healthy subjects. The ...
