Lateralization of motor control refers to the ability to produce pure unilateral or asymmetric movements. It is required for a variety of coordinated activities, including skilled bimanual tasks and locomotion. Here we discuss the neuroanatomical substrates and pathophysiological underpinnings of lateralized motor outputs. Significant breakthroughs have been made in the past few years by studyi...

The purpose of this investigation was to test the ontogenetic principle that the development of proximal postural stability precedes, and is necessary for, the development of distal fine motor control. The Posture and Fine Motor Assessment of Infants (Case-Smith, 1987) was used to examine the relationship between proximal and distal motor function in 60 normal infants. Low positive partial corr...

Objectives: The aim of this study was to determine the effect of Perceptual-motor training on motor skills of normal preschool children (aged 4-6 years) in Esfahan city. Methods: This was a quasi-experimental study with intervention and control groups. Each group included 30 normal preschool children aged 4 to 6 years. They were selected randomly children of intervention group one empowering...

the purpose of this current study was to investigate the influence of perceptual-motor trainings on motor skills of girls with trainable mental retardation. so 20 girls with trainable mental retardation in the town of marivan welfare organization with the average of 8/3 ±1/11 years and iq of 39/14±6/84 with purposive sampling method were studied. all girls were pretested. then samples based on ...

The effect of severe trauma on handedness was studied through patient responses from 146 questionnaires that were correlated with individual chart review. Subjects were asked to designate their hand use preference, before and after injury, when performing 16 activities. The incidence of change in hand use was determined within four diagnostic types and five designated anatomical levels of injur...
