Motor dysfunction in apparently normal high-risk childrenGoyen, Traci-Anne, School of Women???s & Children???s Health, UNSW January 2005 (has links)
Infants born extremely prematurely (ie. <29 weeks gestation) or with extremely low birth weight (ie. <1000 grams) are at high-risk of major and minor motor sequelae that persist into the school years. Most of the research on the outcome of these high-risk infants has concentrated on the prevalence of major disability. The majority of high-risk children at school age have normal intelligence and no sensorineural disability. Despite this, these ???apparently normal??? high-risk children have a higher incidence of minor morbidities. Motor coordination problems are frequently reported, yet further investigation into the emergence of minor motor dysfunction, or its impact on academic achievement and everyday activities is seldom explored. The aim of this thesis was to provide a comprehensive investigation into motor dysfunction, which is commonly found in ???apparently normal??? high-risk children. This was addressed in a series of five studies that intended to provide insight into the emergence, prevalence, nature, and prediction of motor dysfunction in otherwise ???normal??? high-risk children. Study 1 examined the development of gross and fine motor skills from infancy to school age using a longitudinal cohort study design. ???Apparently normal??? high-risk children (n=58) were assessed with the Peabody Developmental Motor Scales at 18 months corrected age, 3 and 5 years. A significant proportion continued to have fine motor deficits to school age (64%), reflecting a persistent problem with fine motor skills throughout this period. The proportion of infants with gross motor deficits significantly increased from 18 months to 5 years (81.1%), particularly for the ???micropreemies???. Whilst there was no gender difference found, the development of gross and fine motor skills appeared to be influenced differently by the home environment. Study 2 examined the impact of motor dysfunction on performance at school age. The prevalence of Developmental Coordination Disorder (DCD) in ???apparently normal??? high-risk children was determined using a controlled cohort study design. In addition, the nature of DCD in this population was explored by testing sensorimotor abilities that possibly underlie the motor dysfunction. Fifty (50) high-risk children with IQ<85 and no identified sensorineural disability were assessed at 8 years of age along with a matched control from their respective class at school. The Movement Assessment Battery for Children and a battery of sensorimotor tests were administered. Results indicated a significantly higher prevalence of DCD (42%) in the high-risk group in comparison to the control group (8%). In relation to sensorimotor abilities that may influence motor performance, the high-risk group scored significantly lower on most of tests, however it was neurological ???soft signs???, postural praxis, and sequencing praxis that contributed to DCD in the high-risk group. Study 3 was designed to investigate the impact of motor dysfunction on a motor-based task performed within the school setting. Specifically, this study described handwriting skills in ???apparently normal??? high-risk children, determined the prevalence of handwriting dysfunction, and investigated sensorimotor abilities that may be associated with problematic handwriting. The high-risk cohort and matched controls described in study 2 were also administered a number of handwriting tests. High-risk children were found to have poorer handwriting legibility and speed in comparison to their classmates. The prevalence of handwriting dysfunction in the high-risk group was 46%, significantly higher than controls (18%). Hand preference, pencil grasp used, and pain whilst writing were comparable to the control group. The contribution of underlying sensorimotor abilities to handwriting dysfunction in the high-risk population however was not evident. By using the same subjects in studies 2 and 3, the co-morbidity of handwriting dysfunction with DCD could be determined. Of those high-risk children identified with DCD, 43% had co-morbid handwriting dysfunction. Study 4 explored the relationship between perinatal and environmental variables to Developmental Coordination Disorder and handwriting dysfunction in high-risk children. Perinatal and environmental variables of the 50 ???apparently normal??? high-risk children that participated in the previous study were analysed. Results indicated prolonged rupture of membranes (PROM) and retinopathy of prematurity (ROP) were significantly and independently associated with DCD, perhaps reflecting the impact of the antenatal infection process and visual development related to ROP on motor outcome in high-risk children. Perinatal variables were not associated with handwriting dysfunction, but high-risk males were more likely to have handwriting dysfunction. Maternal education and paternal occupation were associated with aspects of handwriting. Whilst handwriting is a motor-based activity, it appears to be influenced by environmental variables, similar to other academic areas for the high-risk population. Study 5 sought to determine whether a motor assessment at an earlier age could predict DCD in the ???apparently normal??? high-risk population at school age. Motor assessment at 12 months, 3 and 5 years for the high-risk subjects who participated in study 2 were analysed using Receiver Operator Curves (ROC curves). The 3 year assessment with the Peabody Developmental Motor Scales was the best predictor of DCD at 8 years, with the Griffiths Locomotor Scale at 3 years yielding a similar result. Findings suggest that high-risk children who scored below the specified cut-off points on 3 year motor assessments and who had a history of PROM or ROP were at greater risk of having motor-based problems that had the potential to interfere with functioning at school.

The accuracy of parents' perceptions of their preschool children's gross motor abilitiesGroner, Michael 03 May 1990 (has links)
The purpose of this research was to determine the extent to
which parents and professionals were in agreement prior to and
following intervention regarding their Judgement of the gross motor
abilities of the parents' preschool children.
Each child was tested by a professional on the Ulrich Test of
Gross Motor Development (1985). Dependent measures were parents'
perceptions (N = 28 pairs) of their children's gross motor abilities.
Parents were randomly assigned to either an intervention (treatment)
or non-intervention (control) group. The intervention period included
two-ninety minute videotaped observational training sessions, on how
to observe gross motor patterns in a young child, over a two-week
period. At the conclusion of the intervention period, all parents
completed a questionnaire similar to one completed prior to
intervention. Both questionnaires provided information on parents'
perceptions of their children's gross motor abilities.
Paired-t tests were used to determine if significant differences
existed between parents and professionals prior to intervention.
Paired-t tests were also used following observational training
intervention to analyze any changes over time between the pre-intervention
and post-intervention periods for intervention and nonintervention
parents. Student-t tests were used to compare post-intervention
differences between intervention parents and nonintervention
parents. An alpha level of .10 was used in this study.
The results of the study revealed a significant difference
between parents' perceptions and professional assessments. Most
parents tended to overestimate their children's gross motor abilities
relative to the professional standard. Significant differences were
reported for changes occurring over time between the pre-intervention
and post-intervention periods.
Significant differences also were found between groups following
intervention. Parents receiving observational training demonstrated
more realistic perceptions of their children's gross motor abilities
relative to professional assessments than did parents not receiving
observational training.
As a result of these investigations, it was determined that
parents and professionals were generally not in agreement with
respect to children's current level of functioning in gross motor
abilities. Parents, as previous literature has described, also tended to
overestimate their children's abilities. Furthermore, the introduction
of an intervention program, which trained parents to become better
evaluators of motor ability, resulted in positively influencing parents'
perceptions of their children's gross motor abilities. / Graduation date: 1990
