Emergence and stability of interlimb coordination patterns in children with developmental coordination disorder

The purpose of this study was to investigate the emergence and stability of coordination patterns in children with developmental coordination disorder (DCD) when performing a rhythmic interlimb coordination task on rigid (floor) and elastic (mini-trampoline) surfaces. Twelve typically developing (TD) children and 12 children with DCD were required to clap while jumping under different conditions: in a chosen pattern Free; when the feet touched the surface - Clapping-surface; when the body reached the maximum jumping height, Clapping-jump; and when the feet touched the surface and the body reached the maximum jumping height - Clapping-both. The results showed that the coordination pattern of children with DCD was more variable in the Free, Clapping-surface, and Clapping-jumping conditions and more variable on the mini-trampoline than on the floor under the Free condition when compared with the TD children. Clapping-jumping was more difficult to perform than Clapping-surface for both groups. These findings suggest that the children with DCD were less capable of rhythmically coordinating the jumping-clapping task because they used a type of exploratory strategy regarding the physical properties of the surfaces, whereas the TD children used a type of adaptive strategy displaying behavior that was more consistent across the tasks/environmental demands.

Aquecimento e Desaquecimento Vocal em Estudantes de Pedagogia

Introduction: the voice is one of the main features of interaction between teacher and student. As teachers, future teachers are also risk population for the development of dysphonia and may be subject to protective intervention. Purpose: to evaluate the effect of a vocal warm-up and cool-down procedure at Pedagogy students. Method: A quasi-experimental study, pre-posttest without a control group, with fourteen Pedagogy students at a public university, participants of a short course. The analysis was performed by a self-assessment visual analogue scale of 10 cm, considering aspects related to the body and voice. The protocol was implemented in three steps: pre-test, post warm-up and post cool-down, and it was calculated the averages of the variables of discomfort and compared the measurements before and after performing each procedure. It was used the the Wilcoxon signed-rank statiscal test, adopting a significance level of 5%. Results: there was less discomfort with statistical significance after the vocal warm-up (p=0.002) and cool-down (p=0.001), with greater magnitude in both aspects related to voice. Conclusions: The vocal warm-up and cool-down have positive effects on the perception of students and should be taught to future teachers in order to prevent vocal disorders. The vocal cool-down, poorly researched, should not be passed over vocal health practices since its purpose showed obvious improvement in the investigated group.
