PURPOSE Although visual analysis, motor coordination, and visual-motor integration can each affect performance on a test of visual motor integration, previous studies have not reported the relative importance of these components to the relation between visual motor integration and learning readiness, reading, and math. This investigation relates academic achievement in reading and math to perfo...

the main purpose of this study was to determine which correlate, perceived motor competence or motor skill competence, best predicts girls' physical activity behavior.a sample of 352 girls (mean age=8.7, sd=0.3 yr) participated in this study. to assess motor skill competence and perceived motor competence, each child completed the test of gross motor development-2 and physical ability sub-scale...

Mammalian myosin V motors transport cargo processively along actin filaments. Recent biophysical and structural studies have led to a detailed understanding of the mechanism of myosin V, making it perhaps the best understood cytoskeletal motor. In addition to describing the mechanism, this review will illustrate how “dynamic” single molecule measurements can synergize with “static” protein stru...

background & aim: patients with spinal cord injury (sci) impose a heavy burden on health care system. awareness on prevalence and incidence of sci is important because this would show the necessity of prevention. this study aimed to investigate the epidemiology and types of traumatic spinal cord injuries in a trauma referral center in guilan. methods & materials/patients: this is a descriptive ...

We used a panel design and the Nationwide Inpatient Sample from 19 states between 2003 and 2010 to examine the impact of texting bans on crash-related hospitalizations. We conducted conditional negative binomial regressions with state, year, and month fixed effects to examine changes in crash-related hospitalizations in states after the enactment of a texting ban relative to those in states wit...

The function of the motor cortex has been a persistent mystery. A recent study has found striking correspondence between the descending projections of lamprey pallium and mammalian motor cortex, encouraging comparative studies of the origin (and role) of forebrain motor control.

This article describes an approach to motor synergies that allows them to be quantified in people with atypical movement patterns during exercise or practice. Within this approach, motor variability may be classified with respect to a task-specific performance variable as "good" (not affecting the variable) or "bad" (changing the variable). The authors review studies of motor synergies in peopl...
