Interaction of discrete and rhythmic movements over a wide range of periods.

This study investigates a complex task in which rhythmic and discrete components have to be combined in single-joint elbow rotations. While previous studies of similar tasks already reported that the initiation of the discrete movement is constrained to ...

Do baby walkers delay onset of walking in young children?

Baby walkers have been a source of considerable controversy. Some people suggest developmental benefit from their use while others focus on the potential harm that stems from accidents and even suggest developmental delay. This mini-review aimed to ...

Spatial and temporal constraints on performance in children with movement co-ordination problems.

Eight 10-year-old children manifesting movement co-ordination problems (MCP), as assessed by the Movement Assessment Battery for Children (MABC), and a matched control group of eight children of a similar age without such problems, were required to carry ...

Neural adaptations with chronic activity patterns in able-bodied humans.

The purpose of this article is to review the neural adaptations that occur in able-bodied humans with alterations in chronic patterns of physical activity. The adaptations are categorized as those related to cortical maps, motor command, descending ...

Assessing intrarater, interrater and test-retest reliability of continuous measurements.

In this paper we review the problem of defining and estimating intrarater, interrater and test-retest reliability of continuous measurements. We argue that the usual notion of product-moment correlation is well adapted in a test-retest situation, whereas ...

Learned movements in a left-handed pianist: an f-MRI evaluation.

The spatial arrangement of neuronal sources for digit movement is non somatotopic, and is structured as extensively arranged through different regional cortex. We have functionally examined the cerebro-cortical activation during simple and complex motor ...

Imaging brain plasticity during motor skill learning.

The search for the neural substrates mediating the incremental acquisition of skilled motor behaviors has been the focus of a large body of animal and human studies in the past decade. Much less is known, however, with regard to the dynamic neural ...

Motor sequence learning with the nondominant left hand. A PET functional imaging study.

Whereas the human right hemisphere is active during execution of contralateral hand movements, the left hemisphere is engaged for both contra- and ipsilateral movements, at least for right-handed subjects. Whether this asymmetry is also found during ...

Technique analysis in sports: a critical review.

This paper critically reviews technique analysis as an analytical method used within sports biomechanics as a part of performance analysis. The concept of technique as a specific sequence of movements appears to be well established in the literature, but ...

Modelling coaching practice: the role of instruction and demonstration.

In this paper, we review the empirical literature pertaining to the effectiveness of instructions and movement demonstrations. Initially, we examine existing theories and approaches that try to explain the process of skill acquisition so as to determine ...
