This study attempted to search the nature of language development and the relationship between vocal development and motor development in infancy, and it relied on the descriptive and qualitative approach and the method of content analysis to review and compare three researches related to the relationship of language development and physical…

Music performance requires high levels of motor control. Professional musicians use body movements not only to accomplish and help technical efficiency, but to shape expressive interpretation. Here, we recorded motion and audio data of twenty participants performing four musical fragments varying in the degree of technical difficulty to analyze…

Fine motor skills develop in childhood. In this study, we evaluate motor planning in 6- to 11-year-old children using a pegboard and midline crossing task. The results of the pegboard task showed that children modified their strategies of hand use and space use as a function of age, albeit with a transition in the 8- to 9-year-old children. The…

To harness the complexity of their high-dimensional bodies during sensorimotor development, infants are guided by patterns of freezing and freeing of degrees of freedom. For instance, when learning to reach, infants free the degrees of freedom in their arm proximodistally, that is, from joints that are closer to the body to those that are more…

Autistic children have problems in cognitive and motor skills areas. This study investigated the effects of motor and cognitive problems on daily living activities and quality of life in autistic children. Thirty-two autistic children were included in the study. Thirty typically developing children were selected as the control group. The Bruininks…

Background: There is limited research examining the efficacy of early physical therapy on infants with neuromotor dysfunction. In addition, most early motor interventions have not been directly linked to learning, despite the clear association between motor activity and cognition during infancy. Objective: The aim of this project is to evaluate…

Purpose: The present investigation was designed to study the modulation of abdomen and rib cage movements during vocalization over a period of development associated with rapid decreases in the compliance of the chest wall. Method: Rib cage and abdominal kinematics were recorded during spontaneous vocalizations in 7- and 11-month old infants.…

This study of single-joint elbow flexion movements by 10 subjects with Down's syndrome (ages 14-19) and 6 control subjects concluded that there are no major qualitative deficits in the motor control mechanisms of individuals with Down's syndrome, but there might be problems with proper modulation of motor commands.
