The current study investigated the relationship between Dynavision scores for 36 men and 52 women (M age = 20.5 yr.) and performance on six conventional psychomotor tests which presumably tap similar psychomotor abilities and visuomotor skills. Analysis indicated that initial Dynavision performance was significantly correlated with performance on these common psychomotor tests. These data extend findings that propose the effectiveness of the Dynavision apparatus to assess performance on basic visual-motor and visual-cognitive functions. Taken together with these new results, findings suggest that this apparatus might contribute to psychomotor assessment and may be potentially useful for effective selection and identification of individual differences in human behavioral performance.

Context: Reaction time (RT) is crucial to athletic performance. Therefore, when returning athletes to play following injury, it is important to evaluate RT characteristics ensuring a safe return. The Dynavision D2® system may be utilized as an assessment and rehabilitation aid in the determination of RT under various levels of cognitive load.

Purpose: This article describes the potential of dynamic contrast- enhanced magnetic resonance tomography (DCE-MRT) for the visualization and quantification of blood flow of lower leg muscles at rest and after individually adjusted muscular exercise.
Patients And Methods: Five cases were chosen to exemplify the qualitative and semi-quantitative blood flow evaluation in the lower leg muscles. The crural muscle state was determined with an isometric maximal strength measurement from a female patient with peripheral arterial occlusive disease (pAVK), a male patient with coronary heart disease (KHK) without clinical signs of a pAVK, a volunteer with sufficient physical activity in accordance with the Freiburg Questionnaire of Physical Activity and two professional athletes.
