background: to determine whether using mechanical ventilation in neonatal intensive care unit (nicu) influences motor development of low birth weight (lbw) infants and to compare their motor development with normal birth weight (nbw) infants at the age of 8 to 12 months using peabody developmental motor scale 2 (pdms-2). methods: this cross sectional study was conducted on 70 lbw infants in two...

the purpose of this study was to investigate the effect of a selected motor program (as a motor experience) on manipulative skills in 4-6-year-old boys. 40 subjects were selected randomly using a personal information questionnaire. after the pretest, the ulrich's test of gross motor development (2000) including fundamental motor skills, locomotors skills, manipulative skills and controllin...

This study examined motivational effects of feedback on motor learning. Specifically, we investigated the influence of social-comparative feedback on the learning of a balance task (stabilometer). In addition to veridical feedback (error scores reflecting deviation from the target horizontal platform position) about their own performance after each trial, two groups received false normative inf...

This study examined the acquisition and long-term retention of a gross motor skill, namely, tossing, in 23 moderately to severely demented Alzheimer's disease (AD) patients and 22 health older adults. To identify optimal learning strategies, subjects received 10 weeks of training under either constant or variable practice conditions. Accuracy at the tossing task was assessed immediately, one we...

OBJECTIVE This study investigated the effects of qualitative and quantitative knowledge of results (KR) on the acquisition of a motor skill. It was hypothesized that there would be differences in performance during skill acquisition and retention, depending on the type of feedback given. Qualitative KR was in the form of verbal encouragement and quantitative KR was in the form of an algebraic n...

Learning from past mistakes is of prominent importance for successful future behavior. In the present study, we tested whether reinforcement learning signals in the brain are predictive of adequate learning of a sequence of motor actions. We recorded event-related potentials (ERPs) while subjects engaged in a sequence learning task. The results showed that brain responses to feedback (the feedb...

BACKGROUND Tourette syndrome is a neuropsychiatric disorder characterized by motor and phonic tics. Deficient motor inhibition underlying tics is one of the main hypotheses in its pathophysiology. Therefore the question arises whether this supposed deficient motor inhibition affects also voluntary movements. Despite severe motor tics, different personalities who suffer from Tourette perform suc...

PURPOSE This study examined how performance components and variables in intervention influenced fine motor and functional outcomes in preschool children. METHOD In a sample of 44 preschool-aged children with fine motor delays who received occupational therapy services, eight fine motor and functional performance assessments were administered at the beginning and end of the academic year. Data...

the purpose of this study was to survey motor proficiency in children with adhd. this study was descriptive, comparative and non-intervention. forty children selected by regarding to aims of study and, assigned into two groups (adhd and control) randomly. bruininks-oseretsky test of motor proficiency and conner's parent and teacher questionnaire was used for data collection. the parents or...
