Coordination in front crawl in elite triathletes and elite swimmers.

The aim of this study was to compare the arm coordination in 19 elite triathletes and 15 elite swimmers at six different velocities between 80 % and 100 % of their maximal velocity (Vmax). The different phases of the stroke (A: entry; B: pull; C: push; ...

Effects of normal aging on visuo-motor plasticity.

Normal aging is associated with declines in neurologic function. Uncompensated visual and vestibular problems may have dire consequences including dangerous falls. Visuo-motor plasticity is a form of behavioral neural plasticity, which is important in ...

Birthweight and gestational age effects on motor and social development.

The number of children at risk for delays in motor and social development (MSD) associated with preterm delivery and low birthweight is increasing, but such children are generally not seen as being in need of evaluation. The objective of these analyses ...

Beta-CIT-SPECT combined with UPDRS appears to distinguish different parkinsonian conditions.

OBJECTIVES: An earlier study in l-dopa responding patients with idiopathic Parkinsons disease documented that progressive nigro-striatal degeneration shown with single photon emission computed tomography (SPECT) and the cocain analog iodine-123-beta-CIT ...

Verbal structure of numerals and digits handwriting: new evidence from kinematics.

Two experiments used a digitizing tablet to analyse the temporal, spatial, and kinematic characteristics of handwritten production of arabic numbers. They addressed a specific issue of the numerical domain: Does the lexical and syntactic structure of ...
