QOL-46. EFFECTIVENESS OF A TELEREHABILITATION PROGRAM TO IMPROVE VISUAL PERCEPTION IN CHILDREN AND ADOLESCENTS WITH HEMIANOPIA CONSECUTIVE TO A BRAIN TUMOUR

Abstract BACKGROUND Brain tumours in children often lead to visual impairment, which presents as a significant morbidity for long-term survivors. A recent Children Cancer Survivor Study showed that 22.5% of the patients with astroglial tumours had visual impairment five years after the diagnosis. In the pediatric population with hemianopia, there are no standardized protocols for managing vision loss. This study evaluated a 6-week home-based telerehabilitation program (home-based 3D-MOT-IVR) on visual perception in children with hemianopia consecutive to a brain tumour. METHODS This phase 2a, open-labelled, non-randomized, single-arm study included ten patients aged 12-18 years old with hemianopia consecutive to a pediatric brain tumour. Patients followed a 6-week home-based 3D-MOT-IVR with remote control of the device from the UHN laboratory. Visual assessments were performed at baseline, 2, 4, and 6 weeks, with follow-ups at 1 and 6 months to check the visual field, contrast sensitivity and reading speed. RESULTS The home-based 3D-MOT-IVR intervention proved feasible and safe, with no reported adverse events. All participants completed the prescribed stimulations, pre- and post-intervention assessment points, and 90% completed the follow-ups. Remarkably, the outcomes revealed significant improvements post-intervention: 50% of participants showed enhanced visual perception in their blind field, while 70% exhibited increased reading speed. Importantly, these positive effects were sustained at the 6-month follow-up. A robust correlation emerged between 3D-MOT-IVR performance and improved visual perception in the blind field, emphasizing the intervention’s effectiveness. CONCLUSION These promising results lay a strong foundation for a larger randomized controlled trial, offering hope for a meaningful breakthrough in visual rehabilitation for this vulnerable population. Further studies are being developed to confirm these results and identify the most appropriate schedules to optimize visual outcomes (such as duration and repetition of these programs).

Visual Perception in Children with a History of Hypoglycemia due to Hyperinsulinism.

Hyperinsulinism refers to improper insulin secretion in the presence of low plasma glucose, causing severe and persistent hypoglycemia in infants and children. The brain's occipital lobe, which includes the visual and plays an essential role in visual perception is specifically sensitive to hypoglycemia-induced damage. The present study aims to investigate the visual perception in children suffering from hyperinsulinism and to compare it with the control group. This cross-sectional control study, conducted in 2020 in Isfahan, Iran, involved 20 children aged 4-13 years with hyperinsulinism and 20 healthy children of the same age and gender for comparison. In both groups, the measuring instrument was the Test of Visual Perceptual Skills (non-motor) Third Edition. The mean visual perceptual quotient in the case and control groups was 80.50±26.74 and 116.50±7.56 (p-value<0.001), respectively. The results overall indicated that children suffering from hyperinsulinism were weaker than healthy children in all areas of visual perception. Based on the obtained results, it is recommended that children suffering from hyperinsulinism be screened regarding visual perceptual disorders since this screening may be helpful in initiating different rehabilitation programs among these patients.

Enhancing Visual Perception in Children Ages 4-12 Years: A Systematic Review of Technology-based Interventions

Introduction: Visual perception plays a pivotal role in a child’s overall development and learning. Occupational therapists often employ interventions to support children in enhancing their visual perception skills, with technology-based approaches gaining prominence in recent years. This review intends to highlight the significance of visual perception interventions, especially those involving technology. Aim: To systematically synthesise the literature on the effectiveness of technology-based interventions on visual perception in children with disabilities aged 4-12 years. Materials and Methods: A comprehensive search of studies was conducted using electronic databases (Scopus, PubMed, ProQuest, and OTseeker). Additionally, studies were also considered through manual searches from printed journals (American Journal of Occupational Therapy, British Journal of Occupational Therapy, Canadian Journal of Occupational Therapy, and the Australian Journal of Occupational Therapy) to identify existing technology-based visual perception interventions in children aged 4-12 years. Risk of Bias was conducted through guidelines for systematic review by the American Occupational Therapy Association (AOTA). Data extraction was reported by tabulating author(s) and year, sample characteristics, outcome measures used, study design, intervention details (experimental, comparator, study setting, duration), and outcomes of the studies. Results: In the present review of 13 studies, two studies used iPad interventions, while 11 used computer-based interventions, targeting various clinical groups like developmental delays, dyslexia, cerebral palsy, hearing impairment, down syndrome, hydrocephalus, and special needs. Occupational therapists led most studies, with some involving physiotherapists, educators, and multidisciplinary teams. iPad interventions focused on visual skills with structured apps, while computer methods included games and software like Microsoft Office and Computerised Visual Perception Training (CVPT) for visual training. Positive effects were seen on visual perception and motor skills across different conditions with these technology-based interventions. Conclusion: Visual perception interventions, particularly those incorporating technology, have become invaluable in the field of paediatric occupational therapy. As technology continues to evolve, occupational therapists must remain adaptive and innovative in their strategies to provide the best possible support for children with visual perception difficulties.

The relationship between motor function and visual perception in school-aged children with neurodevelopmental disorders

Motor function and visual perception are key areas of occupational performance skills in which children with neurodevelopmental disorders have deficits that affect their daily activities and tasks, such as writing. Aim: The aim of this study was to investigate the relationship between motor function and visual perception in children with Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) and explore differences in performance between the groups. Methodology: We reviewed the file records of 60 school-aged children (51 boys/9 girls), 30 with ASD (M = 8.53 years) and 30 with ADHD (M = 8.42 years), derived from a university Child Psychiatry Department and including assessments in visual perception (Developmental test of Visual Perception- DTVP-2) and motor function (Movement ABC2- M-ABC2). Results: Results indicated a significant correlation between total motor function performance scores and visual-motor integration categories in children with ASD (r(28)=.70, p&lt;.001) and ADHD (r(28)=.40, p=.03). Manual dexterity and balance were found to predict performance on visual-motor integration in both ASD (F (2,27)=10.94, p&lt;.001) and ADHD (F(1,28)=8.45, p=.007). Children with ASD performed lower than ADHD children in the categories of Aiming and Catching (p=.032) and Balance (p&lt;.001). Conclusions: The findings of the present study highlight the interrelationships between motor function and visual perception as it is manifested in children with ASD and ADHD at school age. In-depth knowledge of how motor function relates to visual perception offers valuable insights, therapeutically and research-wise, to enhance participation in daily activities of children with neurodevelopmental disorders.

Assessment of Visual Perception in Children with Autism Spectrum Disorder

Autism spectrum disease (ASD) is a nervous disorder. In this disease children have sensory processing dysfunction and they unable to communicate, interact, and showed repetition in behaviours. The present study was designed to determine visual impairment frequency in children with autism spectrum disorder (ASD). A descriptive study was performed in Paediatrics Department of Children's Hospital and The Institute of Child Health, Lahore. Data was collected in six months and 52 patients of both gender were considered. A total of 40 boys and 12 girls of 3-8 years old children were included. A structured Questionnaire based on visual perception was designed to determine the visual sensory processing issues in children with an autism spectrum disorder. The findings showed a strong difficulties in the visual sense particularly in differentiation among the colours and eye tracking in autism children. It was concluded that sense of sight highly affected in the patients of autism spectrum disorder.

Association between Visual Perception and Socioeconomic Status in Malaysian Preschool Children: Results from the Test of Visual Perceptual Skills-4

Visual perception in children can be evaluated using the Test of Visual Perceptual Skills-4th edition (TVPS-4) with normative data developed for the U.S. population. It is widely used by healthcare practitioners in Malaysia, despite reports that children in Asia outperform their U.S. peers in visual perception assessment. We compared TVPS-4 scores among 72 Malaysian preschool children (mean age: 5.06 ± 0.11 years) with U.S. norms and investigated the association between socioeconomic factors and TVPS-4 scores. Malaysian preschoolers had significantly higher standard scores (116.60 ± 7.16) than the U.S. norms (100 ± 15; p < 0.001). They also had significantly higher scaled scores (between 12.57 ± 2.10 and 13.89 ± 2.54) than the U.S. norms (10 ± 3, all p < 0.001) for all subtests. Multiple linear regression analyses revealed that socioeconomic variables were not significant predictors for five visual perception subtests and the overall standard score. The visual form constancy score could be predicted by ethnicity (β = -1.874, p = 0.03). The visual sequential memory score could be predicted by the father's employment status (β = 2.399, p < 0.001), mother's employment status (β = 1.303, p = 0.007), and low household income (β = -1.430, p < 0.037). In conclusion, Malaysian preschoolers outperformed their U.S. peers in all TVPS-4 subtests. Socioeconomic variables were associated with visual form constancy and visual sequential memory, but not with the other five subtests or TVPS-4's overall standard scores.

Efficacy of Dual Task Training versus Conventional Therapy on Hand Function and Visual Perception Ability in Children with Cerebral Palsy

This pilot study aimed to assess the effect of dual-task training, compared to conventional therapy on the hand functional ability and visual perception in children with cerebral palsy. It was a pretest-posttest control group design, conducted for 4 weeks with ten children ranged between 5-13 years old. Participants were randomly allocated either to the experimental group (dual-task training) or the control group (conventional treatment). The experimental group received the usual physical therapy session and dual-task training sessions 3 sessions/week for 4 weeks. The control group received only the conventional physical therapy 3 sessions/week for 4 weeks. Fine and gross motor hand function were assessed by the Jebsen-Taylor hand function test and the Motor-free Visual Perception Test 3rd edition was used to assess visual perceptual ability before intervention and at 4 weeks after intervention. Only the experimental group showed an improvement in hand function (p<0.05) and no significant differences were observed between the groups (p>0.05). Statistically significant changes were noticed in three of the five subscales of the visual perception in the experimental group (p<0.05) with the experimental group superior to the control group. These findings suggest that dual-task training conducted with a precise goal to achieve (problem-solving) and including cognitive tasks is beneficial in means of improving hand function and visual perceptional ability of children with hemiplegic cerebral palsy with a short-term effect. However, further studies on children with cerebral palsy with a similar approach are warranted.

Background and Aims: Visual perception skills are essential for daily life activities. The purpose of this study was to investigate the effect of eight-week Wii-Fit training on visual perception in children aged 6 to 10 years with a developmental coordination disorder Methods: The research method was semi-experimental with pre-test and post-test with the control group. The statistical population included all children aged 6 to 10 years in Rafsanjan in the academic year of 2018-19. Of these children, 40 children with developmental coordination disorder were selected by multi-stage available sampling method and randomly assigned to experimental and control groups. Research instruments were Wilson's Developmental Coordination Disorders Questionnaire, Movement Assessment Buttery for Children (MABC), and Gardner's Visual Perception Test. Subjects in the experimental group performed the individual Wii fit training for 16 sessions (8 weeks and two sessions per week). The Shapiro-Wilk, Levin test and 95% confidence level covariance were used for data analysis. Results: The results showed that timely interventions based on active video games significantly affected children's visual perception with developmental coordination disorder (P˂0.05). Conclusion: According to the results, the emphasis on identifying and performing appropriate interventions such as Wii Fit training may be effective in treating and developing children with developmental coordination disorder.

Parents’ Perception of School-aged Children’s Body Weight, Height, and Body Shape

ABSTRACT Background: Parents have important roles to perceive the growth abnormalities of their children. Parental misperception can affect the children’s long-term health problems. Aim: To investigate: (a) the accuracy of parents’ perception of children’s weight, height, and body shape, (b) the effects of misperception in caring for children’s health, and (c) the factors of parental misperception. Methods: A cross-sectional study was conducted at a primary school in Bangkok, Thailand. A total of 1,153 parents completed self-administered questionnaires: (1) verbal perception of children’s weight and height and (2) visual perception of children’s body shape using Children’s Body Image Scale developed by Truby H and Paxtron SJ. Results: The agreement of parents’ perception and children’s actual weight and height was fair (K = 0.33 and 0.27, respectively). While the agreement of parents’ perception of boys’ and girls’ body shape was moderate (K = 0.43 and 0.48, respectively). Parents who underestimated children’s weight and height were likely to seek medical care (OR = 1.92; 95% CI 1.39, 2.65 and OR = 3.73; 95% CI 2.56, 5.44, respectively). Nonetheless, parents tended to underestimate the boys’ weight. Conclusion: Many parents do not accurately perceive their children’s weight, height, and body shape. This misperception could influence their caring for children’s health. Thus, educating parents about the perception of children’s growth should be emphasized to avoid long-term health effects.

The Effect of Convergence Vision Therapy on Symptoms and Visual Perception in Children with ADHD tendency

The purpose of this study is to determine whether vision therapy improves symptom and visual perceptual skills in children with attention deficit hyperactivity disorder tendency who have visual problems. The subjects of this study were 10 children. Before and after vision therapy, the visual function test, developmental test of visual-motor integration, test of visual perceptual skills, and ADHD rating scale test were performed. Vision therapy was conducted twice a week for a period of 6 months to 1 year. After vision therapy, all subjects achieved normal ranges of visual function, sensory fusion, stereoacuity, vergence function, and convergence. The visual function and visual perceptual skill were improved and the score for ADHD symptoms was reduced. Therefore, it seems that vision therapy can be used to improve the symptoms and visual perception of children with ADHD.

Exploring the spatial working memory and visual perception in children with autism spectrum disorder and general population with high autism-like traits.

The aim of the study is to compare the spatial working memory and visual perception between children with autism spectrum disorder (ASD) and typically developing control (TDC). Furthermore, this study validated whether this impairment was a feature of autism in general population with different autism-like traits (ALTs). This study contains two parts: case-control study and community population study. The ASD group and the control group were enlisted voluntarily (ASD group, n = 52; control group, n = 32). In the population study, we recruited 2994 children. Based on the scores of Autism Spectrum Quotient (AQ), children were divided into two groups (higher ALTs n = 122, lower ALTs n = 122). The participants completed the cognition tasks focusing on spatial working memory, visual-motor integration, and Intelligence. Analysis of covariance (ANCOVA) was conducted, with potential confounders IQ, age, and gender were controlled. Pearson correlations were computed by controlling the IQ and age as covariate to better understand the relations between visual perception, spatial working memory, and autism-like traits. In the case-control study, the results of cognition tasks focusing on the spatial working memory and visual perception indicated underperformance in children with ASD. In the community population study, we found that individuals with higher ALTs performed worse than children with lower ALTs in spatial working memory. Pearson correlation analysis suggested that a correlation between SWM total errors and visual perception was identified both in the children with ASD and in community population (ASD group, r = -0.592, p<0.001; general population, r = -0.201, p = 0.003). It suggested that spatial working memory deficit was a characteristic of autism, and may be distributed across the general population. Furthermore, we speculated a correlation between spatial working memory and visual perception in children with ASD and in general population.

The Broader Autism Phenotype and Visual Perception in Children.

Atypical visual perception has increasingly been described in individuals with autism spectrum disorders (ASD) and linked to quantitative, autism-like features that are present in children and adults without ASD. We investigated whether individual differences in visual processing skills were related to quantitative measures of autism traits in a pediatric sample with a range of clinical features. Visual processing was comprehensively characterized using the test of visual perceptual skills (TVPS), a standardized test of visual perception with seven subtests that capture a range of visual processing abilities. The TVPS Figure Ground (TVPS-FG) subtest requires an individual to disembed a smaller figure from a larger scene. TVPS-FG subtest scores were positively correlated with children's autism features as measured by a parental report of the Broader Autism Phenotype Questionnaire (BAP-Q). The correlation with BAP-Q was specific to the TVPS-FG subtest, as the other TVPS subtest scores were not significantly related to the BAP-Q. This adds to the growing body of research documenting that atypical visual processing is associated with the autism phenotype and highlights the importance of capturing quantitative traits in heterogeneous developmental brain disorders.
