The effect of a scissor skills program on bilateral fine motor skills in preschool children in South Africa including skill improvement, equivalence, transferability of skills and skill retentionRatcliffe, Ingrid 27 January 2010 (has links)
Thesis (Ph.D.), Faculty of Health Sciences, University of the Witwatersrand, 2009 / The purpose of this study was to assess the improvement of scissor skills
after a graded scissor skills program in preschool children in South Africa
(SA).
A bilateral fine motor skills assessment tool was developed for use in this
research. This task-based assessment included every day activities required
at school as well as personal management items. This research phase
included the development of the test items and test instructions, scoring as
well as validity and reliability testing of the assessment.
A suitable scissor skills program was then developed for Grade 0 children in
South Africa. The program was validated by a pilot study and also by a focus
group of occupational therapists. Some changes were made to the picture
selection, the grading of the program, as well as to teacher instructions on
how to present the program before it was finalised and ready for use in the
implementation phase of the research study.
The implementation phase of the study included the individual assessment of
149 learners (mean age of 5 years 6 months), from three different schools in
South Africa. The main aim was to establish the effectiveness of the scissor
skills program by measuring skill improvement, transferability of skills and skill
retention. A further aim was to compare the difference of skill levels of
learners from various socio-economic backgrounds in South Africa.
The results showed statistically significant improvement in scissor skills in all
groups from the three different schools, as well as an ability to retain the learnt
skills. Participants from lower socio-economic backgrounds demonstrated the
least skill initially but made the greatest gains during the program, at times
decreasing the gap between themselves and other participants.
It was concluded that children benefited from a graded scissor skills program,
which allowed them to improve and retain their scissor skills but improvement
did not transfer to other fine motor tasks.

An investigation into the effect of a stetro pencil grip on the writing and pencil grasp of grade 2 children with handwriting difficultiesSmit, Esmie 07 February 2014 (has links)
Research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the Master of Science in Occupational Therapy, Johannesburg, June 2013 / The effectiveness of the Stetro pencil grip in 45 Grade 2 learners with handwriting difficulties was investigated. Monthly assessments considered descriptors including the position joints when writing, the position of the pencil in the hand, hand and arm movements, arm position and posture when writing as well as pencil grasp, the speed and quality of handwriting and tripod pinch strength.
The experimental participants used a Stetro pencil grip for two months after which it was removed for one month. The control participants wrote without a pencil grip. Statistically significant improvement was found for the experimental group in the efficiency of their pencil grasps and their use of their fingers when writing.
The quality and speed of writing and the pinch strength improved in both groups with the experimental group showing significant change in their index finger DIP position. The use of the Stetro pencil grip was effective in resolving inefficient pencil grasps in 70% of the experimental group.

The Relationship Between Instrumental Music Training and Corpus Callosum GrowthVan Hook, Colin January 2004 (has links)
Thesis advisor: Ellen Winner / Recent studies have shown differences between several structures in the brains of professional level musicians and non-musicians. Professional musicians form an ideal group to study changes in the human brain due to the unique abilities required of them. Since many musicians begin training at a young age, it is assumed that these differences are attributable to intense, early experience brought on by the cognitive and motor demands of music training. However, it remains to be seen whether these structural differences are due to changes brought on by experience or preexisting ones which draw children to music lessons. Using magnetic resonance images, I compared the size of the corpus callosums in two groups of children who ranged between the ages of five and seven, one just beginning music lessons and another not beginning music lessons. I also compared the groups in terms of their performance on a finger tapping test for differences in speed and accuracy. A second set of comparisons of callosal size was conducted between nine-to-eleven-year-olds who had been taking music lessons for at least a year and those who had not. Differences in the five-to-seven-year-olds were seen in the anterior corpus callosum corrected for brain volume between the musician and non-musician groups. Differences in accuracy of finger tapping were seen between the musicians and non musicians, as well as between those in the musician group who had received less than sixteen or twenty-five weeks of training versus those who had received less. These findings indicate that while musicians start out with at least one slightly larger measure of corpus callosum size, differences in finger skill tend to develop slowly. / Thesis (BA) — Boston College, 2004. / Submitted to: Boston College.

Gesture Production, Motor Skills, and Disfluencies Observed in Typically Developing PreschoolersBeatty, Christina 31 July 2012 (has links)
Interest in gesture production has considerably increased in recent decades, yet few studies have examined the preschool population. Even fewer studies have examined the intriguing interaction between motor skills and gesture. The original intent of this study was to investigate the relationship of gesture and motor skills in individuals who stutter. However due to recruitment limitations the enrolled sample consists solely of typically developing preschoolers, 3:8 to 6:6 years. Data are presented on gestures and disfluencies during spontaneous speech, a cartoon narration, and a video narration. Additionally, disfluencies were observed during a procedural description task with restricted hand use and hand tapping. Data indicated that higher frequencies of gestures and disfluencies were seen during the cartoon narration. A greater frequency of disfluencies was also experienced with restricted hand use. Relationships between the variables were also explored. Limitations and implications of these results are discussed from both theoretical and clinical perspectives. / Rangos School of Health Sciences / Speech-Language Pathology (SLP) / MS / Thesis

Proportional and non-proportional transfer of movement sequencesWilde, Heather Jo 12 April 2006 (has links)
The ability of spatial transfer to occur in movement sequences is reflected upon in theoretical perspectives, but limited research has been done to verify to what extent spatial characteristics of a sequential learning task occur. Three experiments were designed to determine participants ability to transfer a learned movement sequence to new spatial locations. A 16-element dynamic arm movement sequence was used in all experiments. The task required participants to move a horizontal lever to sequentially projected targets. Experiment 1 included 2 groups. One group practiced a pattern in which targets were located at 20, 40, 60, and 80° from the start position. The other group practiced a pattern with targets at 20, 26.67, 60, and 80°. The results indicated that participants could effectively transfer to new target configurations regardless of whether they required proportional or non-proportional spatial changes to the movement pattern. Experiment 2 assessed the effects of extended practice on proportional and non-proportional spatial transfer. The data indicated that while participants can effectively transfer to both proportional and non-proportional spatial transfer conditions after one day of practice, they are only effective at transferring to proportional transfer conditions after 4 days of practice. The results are discussed in terms of the mechanism by which response sequences become increasingly specific over extended practice in an attempt to optimize movement production. Just as response sequences became more fluent and thus more specific with extended practice in Experiment 2, Experiment 3 tested whether this stage of specificity may occur sooner in an easier task than in a more difficult task. The 2 groups in Experiment 3 included a less difficult sequential pattern practiced over either 1 or 4 days. The results support the existence of practice improvement limitations based upon simplicity versus complexity of the task.

Impact of sensory responses and motor skills on functional skills in activities of daily living of pre-school children with autism spectrum disordersJasmin, Emmanuelle. January 2007 (has links)
Background. In children with autism spectrum disorders (ASD), sensori-motor development and functional skills in activities of daily living (ADL) remain little explored in comparison to the other domains of development. Objectives. To determine the impact of sensori-motor skills on functional skills in ADL of preschool children with ASD, and to examine their type of sensory responses, their motor skills and their functional skills in ADL. Methods. This project is a pilot and cross-sectional study. Thirty-five children with ASD, three to four years of age, have been recruited and assessed. Control groups are also included: eight children with developmental delay (DD) and five children with typical development (TD). A battery of diagnostic and clinical tests was used. Results. ASD and DD groups have significantly more atypical sensory responses than the TD group as measured by the Sensory Profile. The ASD group has significantly poorer motor skills than controls (TD and DD) based on the Peabody Developmental Motor Scales --2nd edition (PDMS-2). Self-care skills of the ASD group fall below 2 standard deviations (SD) on the Functional Independence Measure for Children (WeeFIM). Daily living skills (DLS) of the ASD group are significantly poorer than controls on the Vineland Adaptive Behavior Scales -- Second Edition (VABS-II). The largest percentage of variability in self-care skills, as measured by the WeeFIM, is explained by cognitive functioning and auditory processing, while personal skills, as measured by the VABS-II, are predicted by fine motor skills and sensory avoiding. Conclusion. Pre-school children with ASD, but also children with DD, react differently to sensory stimuli than typically developing children. Also, children with ASD have significantly poorer motor skills than DD and TD children. These sensory and motor difficulties affect the functional skills in ADL. Therefore, it will be important clinically to individually assess and consider sensori-motor and functional skills in ADL of children with ASD. Future interventions may then aim at improving and supporting the development and autonomy of these children. In turn this may assist caregivers by reducing their care load. / Keywords: autism spectrum disorders, sensory responses, motor skills, functional skills, activities of daily living

An Examination of Motor Skills in Children who Stutter2012 August 1900 (has links)
Recently, research has postulated that stuttering is a motor disorder that results from brain abnormalities within the central nervous system. Based on evidence of numerous irregularities within various motor systems, it has been suggested that other motor domains may be comprised. In particular, research in individuals who stutter has found fine, gross, and visual-spatial motor impairment. These studies, though, are dated, have numerous methodological concerns, or yielded contradictory results. Thus, this study investigated whether motor skills in children who stutter (CWS) were compromised. Fine motor skills are important in a school environment because students are required to utilize these skills to complete various assignments and projects, such as cutting and folding paper. Gross motor skills are equally as important as children use these skills to move around their environment. Visual-spatial motor skills are vital for children as they are often required to copy notes off of the board. Deficits in any of these areas may have potentially harmful effects on school performance. Thus, in a school setting, school psychologists are a valuable asset, as they are trained to consult and work with "at risk" populations to prevent long-term problems. Given the potential motor deficits in CWS, school psychologists can intervene and provide appropriate accommodations to remediate any motor deficits.
Participants included 12 CWS and 12 children who do not stutter (CWNS). Participants were recruited from a large urban school district and were administered the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (Bruininks & Bruininks, 2005; BOT-2). Parents completed a demographic questionnaire. One Way Analyses of Variance (ANOVAs) were calculated to compare group means. Results indicated that CWS performed poorer on all but one motor area. Given these results, when a child is identified with a disfluency problem, a broader consideration of issues that may be facing the child is warranted. In particular, school psychologists are in a position to intervene and provide appropriate services to an "at risk" population (i.e., CWS) by conducting a brief motor assessment to identify motor strengths and weaknesses. If warranted, school psychologists can provide accommodations and services to address any identified weaknesses in motor areas.
