A music- and game-based oral health education for visually impaired school children; multilevel analysis of a cluster randomized controlled trial.

BACKGROUND: Visually impaired children encounter some challenges for their oral health. We aimed to compare the effectiveness of oral health education using Audio Tactile Performance (ATP) technique alone, ATP combined with oral health education for mothers, and ATP along with art package on the oral health status of visually impaired children. MATERIALS AND METHODS: This cluster, randomized trial, included visually impaired children from preschool to 10th grade (32 classes, n = 200), in Tehran, Iran, in 2018-2019. A questionnaire was filled out through face to face interviews at baseline regarding age, gender, status of visual impairment, and place of residence. The Simplified Oral Hygiene Index (OHI-S) and Bleeding on Probing (BOP) were examined afterward. Classes were randomly assigned to three groups through simple randomization: 1. Art group (ATP, game-based, and music-based education (11 classes, n = 66); 2. Mothers group (children received ATP and their mothers received education by telephone (10 classes, n = 73); and 3. Control group (children received ATP (11 classes, n = 61). Children received reinforcement after 1 and 2 weeks. Follow-up oral examinations were performed after 1 and 2 months by a blind calibrated examiner. Descriptive statistics were performed using Chi-Square, and ANOVA tests by SPSS (version 22). In analytic statistics, two-level mixed-effects models for BOP and OHI-S were fitted using the Statistical Analysis Software (SAS) version 9.4. Both models fitted with the grouping variable and time (baseline, 1, and 2 months after interventions) as the fixed effects. RESULTS: The mean age (SD) of the children was 12.29 (3.45) years (range: 6-17). Male children (67%) more than female children (33%) participated in the study. Also, 35.5% were blind, and 12% resided at the dormitory. The art and mothers groups had no statistically significant difference compared with the control group, in terms of OHI-S (P = 0.92, and 0.39, respectively) and BOP (OR = 0.64, and 0.66, respectively). The time effect was statistically significant in both BOP and OHI-S models (P < 0.0001). CONCLUSIONS: ATP technique is an effective method to improve the oral health status of visually impaired school children. Oral health promotion programs can be done using this method to tackle oral hygiene problems in visually impaired children. TRIAL REGISTRATION: (https://www.irct.ir/trial/34676: Nov 29th, 2018).

On being a pathologist: a pathway to pathology practice; the added value of supplemental vocational training and mentoring in college and medical school.

Traditionally, vocational training and liberal arts (and premedical) curricula have been separate education tracks. This personal profile describes a program that evolved from the partial fusion of vocational training and a premedical education track. My personal health issue, visual impairment, which presumably resulted as a complication of congenital toxoplasmosis, hampered my ability to read in grammar school and necessitated my placement in remedial reading classes until eighth grade. My father created an independent home-based vocational training program that ran in parallel to my traditional school education all the way through college. In this case study, I provide an overview of this hybrid education program, which we refer to as the Vocational Training/Medical College Curriculum of the Future (VTMC). This term implies that the education of a student from K-12 school through medical college is a continuum. I find it useful to conceptualize a single education continuum beginning with vocational training and ending with medical education, with a large overlap area in the middle. In this paper, I describe a set of my work experiences that leveraged and reinforced my didactic education experiences. Mentors who supported aspects of the VTMC program have included a college president, a US Congressman, a Nobel Laureate, and a Massachusetts General Hospital leader in academic pathology. Elements of this innovative VTMC program have been used in K-12 public schools and in nonmedical graduate school programs.

Ayudas ópticas y no ópticas en la baja visión / Visual and not visual aid in low vision

Este estudio se propone conocer la ayuda visual mejor aceptada por pacientes de visión baja, para lo cual se realizó una revisión bibliográfica con el fin de contribuir al ejercicio optométrico. Se revisaron un total de 28 artículos del año 2007 a la fecha actual. En las diferentes patologías en estudio se encontró que la ayuda visual mejor aceptada para la visión cercana fueron las lupas, y para la visión lejana eran más usados los telescopios(AU)

The aim of this study is to determine which is the most frequent visual aid use in low vision. Twenty-eight articles were consulted in a period from 2007 until now. It was observed that for near vision the hans spectacles were the best aid and for far vision telescope were more used(AU)

Virtual environment navigation with look-around mode to explore new real spaces by people who are blind.

BACKGROUND: This paper examines the ability of people who are blind to construct a mental map and perform orientation tasks in real space by using Nintendo Wii technologies to explore virtual environments. The participant explores new spaces through haptic and auditory feedback triggered by pointing or walking in the virtual environments and later constructs a mental map, which can be used to navigate in real space. METHODS: The study included 10 participants who were congenitally or adventitiously blind, divided into experimental and control groups. The research was implemented by using virtual environments exploration and orientation tasks in real spaces, using both qualitative and quantitative methods in its methodology. RESULTS: The results show that the mode of exploration afforded to the experimental group is radically new in orientation and mobility training; as a result 60% of the experimental participants constructed mental maps that were based on map model, compared with only 30% of the control group participants. CONCLUSIONS: Using technology that enabled them to explore and to collect spatial information in a way that does not exist in real space influenced the ability of the experimental group to construct a mental map based on the map model. Implications for rehabilitation The virtual cane system for the first time enables people who are blind to explore and collect spatial information via the look-around mode in addition to the walk-around mode. People who are blind prefer to use look-around mode to explore new spaces, as opposed to the walking mode. Although the look-around mode requires users to establish a complex collecting and processing procedure for the spatial data, people who are blind using this mode are able to construct a mental map as a map model. For people who are blind (as for the sighted) construction of a mental map based on map model offers more flexibility in choosing a walking path in a real space, accounting for changes that occur in the space.

Perception of Complete Visually Impaired Children to Three Different Oral Health Education Methods: A Preliminary Study.

AIM: To evaluate the perception of visually impaired children to three different methods of oral health education. STUDY DESIGN: Sixty total visually impaired children were divided into three groups of 20 children each. Children in group-I received oral health education through a lecture. Children in group II received Demonstration on a Model by Tell and Touch method (DMTT) and children in group III were self trained on oral hygiene skills. All children received written instructions in Braille. Their knowledge and practice of oral hygiene methods were recorded by a questionnaire and their method of brushing and rinsing was assessed during a personal interview. Data obtained was subjected to statistical analysis. RESULTS: Children in group II were able to brush and rinse significantly better (p <0.05) as compared to the other groups. Demonstration on a Model by Tell and Touch method was found to be the most preferred method of oral health education. CONCLUSION: Oral health education given through DMTT method was perceived well by the visually impaired children.

Eighty eight percent of children are physically active, 22 percent had global malnutrition (weight/age), 20.3 percent growth retardation (height/age) and 37.1 percent overweight and obesity (BMI/age). Visually impaired children showed higher percentages of malnutrition and growth retardation and also higher percentages of overweight and obesity than those with hearing disabilities, who had normal nutritional status (statistically significant difference, p< 0.000. Conclusions: Children with visual impairment show mild malnutrition and risk of obesity and overweight. Most of children do regular physical activity(AU)

The effectiveness of the computerized visual perceptual training program on individuals with Down syndrome: An fMRI study.

This study investigated the effectiveness of the Computerized Visual Perception Training (CVPT) program on individuals with Down syndrome (DS, mean age=13.17±4.35years, age range: 6.54-20.75 years). All participants have mild intellectual disability classified by the standard IQ measures (mean=61.2, ranges from 55 to 68). Both the Test of Visual Perceptual Skill- Third Edition (TVPS-3) and functional magnetic resonance imaging (fMRI) were used to evaluate the training outcomes. Results of TVPS-3 and fMRI showed that DS group had visual perceptual deficits and abnormal neural networks related to visual organization. The results showed that DS intervention group had significant improvements on TVPS-3 after intervention. The fMRI results indicated more activation in superior and inferior parietal lobes (spatial manipulation), as well as precentral gyrus and dorsal premotor cortex (motor imagery) in DS intervention group. The CVPT program was effective in improving visual perceptual functions and enhancing associated cortical activations in DS.

Understanding the Relationship Between Teacher Behavior and Motivation in Students with Acquired Deafblindness.

Because little is known about teacher-student relationships that involve students with acquired deafblindness, the authors performed a multiple case study with a multiple-method design to investigate the relationship between need-supportive teaching behaviors and student engagement. Using self-determination theory (Deci & Ryan, 2000), they analyzed video observations of interactions. It was found that teachers' provision of structure, autonomy support, and involvement often cooccurs with higher levels of student engagement. Moreover, varying degrees of need support over time seem to result in varying levels of student engagement. Examples are provided of need-supportive teaching behaviors that can be used to foster the motivation of students with acquired deafblindness.

Analysis of Interaction and Attention Processes in a Child With Congenital Deafblindness.

Children with deafblindness need support to be able to understand the world and to have access to information. The authors analyzed a dyad consisting of a child with congenital deafblindness and a specialized teacher. The study included participant observations and audiovisual recordings. It was found that the child showed attention to the teacher in activities involving music and rhythm. As potential forms of nonverbal communication, the child presented vocalization, touch, body contact, body movements, facial expressions, and tears. The teacher's forms of communication were verbal, touch, visual, rhythm, and sign language. It was concluded that a significant communication partner is essential to identify, interpret, and respond to attention and communicative behaviors. Use of other forms of communication must comply with individual characteristics so that the child with deafblindness can receive information from the environment through these senses and thus be guaranteed access to the world.

Increasing Self-Regulation and Classroom Participation of a Child Who Is Deafblind.

Self-regulation has been identified as essential to school success. However, for a variety of reasons, its development may be compromised in children and youth who are deafblind. A single-case multiple-baseline study of a child who was deafblind examined the effects of three groups of evidence-based interventions on variables thought to be associated with self-regulation. The dependent variables were (a) frequency and duration of behaviors thought to indicate dysregulation, (b) active participation in school activities, and (c) time from onset of behaviors indicating dysregulation until achievement of a calm, regulated state. The interventions, which included provision of meaningful, enjoyable, and interactive activities, anticipatory strategies, and calming strategies, significantly influenced the dependent variables and are described in detail.

Supporting Blind Students in STEM Education in Austria.

Equal access to education will foster a knowledge society for all. In particular for the ICT based information society a benchmark has been set to raise the numbers of graduates in science, technology, engineering and mathematics (STEM) study courses by 15% (748.000) per year, asking for increased efforts in Europe (http://ec.europa.eu/education/policy/strategic-framework/index_en.htm). This holds even more true for people with disabilities who a) participate in and graduate from STEM at a much lower number and b) face a much higher unemployment rate, in particular in STEM related fields. This asks for sound and well-founded education - first and foremost in math - for people with disability and here especially for blind people.

Educational Applications for Blind and Partially Sighted Pupils Based on Speech Technologies for Serbian.

The inclusion of persons with disabilities has always represented an important issue. Advancements within the field of computer science have enabled the development of different types of aids, which have significantly improved the quality of life of the disabled. However, for some disabilities, such as visual impairment, the purpose of these aids is to establish an alternative communication channel and thus overcome the user's disability. Speech technologies play the crucial role in this process. This paper presents the ongoing efforts to create a set of educational applications based on speech technologies for Serbian for the early stages of education of blind and partially sighted children. Two educational applications dealing with memory exercises and comprehension of geometrical shapes are presented, along with the initial tests results obtained from research including visually impaired pupils.

Observing the use of tactile schedules.

This article explores the use of tactile schedules in a heterogeneous sample of children with congenital blindness and varying degrees of additional disabilities. Basic conditions for the use of tactile schedules are proposed and discussed. Child behaviour indicative of some particular functions that can be attained with the use of tactile schedules, such as sense of agency and increased predictability and communication, is described and discussed. The role of the teacher is emphasized throughout the article.

First steps in the journey from consumers to producers of research in deaf education.

Faculty shortages in the study of low-incidence sensory disabilities (deafness, blindness, deaf-blindness) constitute personnel preparation challenges, as documented by a variety of organizations. To alleviate this deficit in the low-incidence sensory disability professoriat, the National Leadership Consortium for Sensory Disabilities (NLCSD) was created to support the preparation of preservice researchers in these disciplines. This qualitative study documents the emerging perceptions of research by deafness-focused NLCSD first-year doctoral Fellows during their participation in an online enrichment seminar. Thematic analysis of the online interactions of the Fellows reveals their initial steps in their journey from consumers to producers of research. Results of the study offer insight into the preparation process of leadership personnel in deaf education.

The influence of assistive technology devices on the performance of activities by visually impaired / A influência de recursos de tecnologia assistiva sobre a performance em atividades de deficientes visuais

Objective: To establish the influence of assistive technology devices (ATDs) on the performance of activities by visually impaired schoolchildren in the resource room. Methods: A qualitative study that comprised observation and an educational intervention in the resource room. The study population comprised six visually impaired schoolchildren aged 12 to 14 years old. The participants were subjected to an eye examination, prescribed ATDs comprising optical and non-optical devices, and provided an orientation on the use of computers. The participants were assessed based on eye/object distance, font size, and time to read a computer screen and printed text. Results: The ophthalmological conditions included corneal opacity, retinochoroiditis, retinopathy of prematurity, aniridia, and congenital cataracts. Far visual acuity varied from 20/200 to 20/800 and near visual acuity from 0.8 to 6 M. Telescopes, spherical lenses, and support magnifying glasses were prescribed. Three out of five participants with low vision after intervention could decrease the font size on the screen computer, and most participants (83.3%) reduced their reading time at the second observation session. Relative to the printed text, all the participants with low vision were able to read text written in smaller font sizes and reduced their reading time at the second observation session. Conclusion: Reading skills improved after the use of ATDs, which allowed the participants to perform their school tasks equally to their classmates. .

Objetivo: Verificar a influência da utilização de recursos de tecnologia assistiva no desempenho de escolares com deficiência visual em atividades em sala de recursos. Métodos: Realizou-se pesquisa qualitativa, por meio de observação e intervenção educacional em sala de recursos. A população foi composta por seis escolares com deficiência visual situados na faixa etária entre 12 e 14 anos. Os escolares fizeram exame oftalmológico e receberam prescrição de recursos de tecnologia assistiva distribuídos em recursos ópticos, não-ópticos e orientação para uso da informática. Foram observados quanto à distância olho-objeto, tamanho de fonte e tempo de leitura. Resultados: Diagnósticos oftalmológicos: opacidade corneana, retinocoroidite, retinopatia da prematuridade, aniridia e catarata congênita. A acuidade visual para longe variou de 20/200 a 20/800 e para perto de 0,8 M a 6 M. Foram prescritos telescópios, lentes esféricas e lupas de apoio. Comparando-se o tamanho de fonte utilizado no computador verificou-se que na segunda observação, três dos cinco escolares com baixa visão leram fontes menores no computador e a maioria (83,3%) melhorou o tempo de leitura na segunda observação. Em relação ao tamanho de fonte e tempo utilizado para lerem os textos impressos, todos os escolares com baixa visão conseguiram ver tipos menores e diminuíram o tempo de leitura na segunda observação. Conclusão: Constatou-se o melhor desempenho das habilidades de leitura, após o uso de recursos de tecnologia assistiva, o que facilitou a realização de atividades acadêmicas em igualdade aos colegas da sala. .
