RESUMEN
Purpose: To adapt the Participation and Environment Measure for Children and Youth for use with Chinese children and youths, and to investigate its psychometric properties.Materials and methods: The Participation and Environment Measure for Children and Youth was translated into Chinese using a cultural adaptation process. Parents of 69 children aged 5-12 years with disabilities and 319 children without disabilities completed the questionnaires. Internal consistency, test-retest reliability, factorial structure, and known-group validity were examined using Cronbach's alpha, intraclass correlation coefficient, confirmatory factor analysis and t-test, respectively.Results: We added and/or replaced activities with culturally-relevant activities in the Chinese version. Internal consistency was acceptable for most of the scales (0.55-0.86). Test-retest reliability of the summary scores was moderate to high (0.70-0.84). Data-model fit was confirmed in a one-factor structure for the participation scales and a two-factor structure for the environment scales. There were also significant differences in the summary scores between 65 gender- and age-matched pairs of children with and without disabilities on the school participation scales and all the environment scales.Conclusion: This study provides psychometric evidence supporting the use of the Participation and Environment Measure for Children and Youth to assess Chinese children's participation and environmental supports/barriers.Implications for rehabilitationThe Chinese version of the Participation and Environment Measure for Children and Youth was developed through a rigorous translation and cultural adaptation process.There is evidence for the reliability (internal consistency and test-retest reliability) and construct validity (factorial structure and known-group validity) of the Chinese version of the Participation and Environment Measure for Children and Youth.The Chinese version of the Participation and Environment Measure for Children and Youth can be used to assess children's participation in home, school and community settings and to identify environmental barriers that require further intervention.

AIMS: This pilot study investigated perceptual and electrophysiological characteristics of dyslexic children, and evaluated the immediate and prolonged effect of visual perceptual training on these characteristics in these children. METHODS AND PROCEDURES: Seven dyslexic children and seven controls aged 7-8 years were recruited and completed this study. All dyslexic children completed 10-weeks of visual perceptual training. The visual perceptual skills were assessed and binocular visual evoked potentials (VEP) were recorded with two different pattern stimulations initially (Baseline), 3 months after the first assessment (Evaluation I) and 6 months after first assessment (Evaluation II). OUTCOMES AND RESULTS: A significant reduction (pâ¯=â¯0.021) in VEP amplitudes in the dyslexic subjects in response to 15â¯Hz reversal frequency at 15% contrast stimulation was found, compared with controls, prior to perceptual training. A significant correlation (pâ¯=â¯0.005) was found between the VEP amplitude with 15â¯Hz reversal frequency and the total score of Test of Visual Perceptual Skills (non-motor) - revised (TVPS-R). After training, dyslexic subjects scored higher in some of the visual perceptual tasks and these improvements persisted for 3 months. However, the VEP amplitude in the dyslexics showed no significant change after perceptual training.

PURPOSE: Although superior performance in visual motor and visual perceptual skills of preschool children has been documented in the Chinese population, a normative database is only available for the US population. This study aimed to determine the normative values for these visuomotor and visual perceptual tests for preschool children in the Hong Kong Chinese population and to investigate the effect of fundamental visual functions on visuomotor and visual perceptual skills. METHODS: One hundred seventy-four children from six different kindergartens in Hong Kong were recruited. Distance visual acuity, near visual acuity, and stereopsis were tested, along with two measures of visual perception (VP): Visual-Motor Integration (VMI) and Test of Visual-Perceptual Skills (TVPS). Raw VMI and TVPS scores were converted into standard/scaled scores. The impact of basic visual functions on VP (VMI and TVPS) was examined using multiple regression. RESULTS: Visual functions were generally good: only 9.2 and 4.6% of subjects had unilateral and bilateral reduced habitual vision, respectively (distance visual acuity in the better eye >0.3 logMAR [logarithm of the minimum angle of resolution]). Performance in the VMI and in the visual memory and spatial relationships subtests of the TVPS exceeded that reported for age-matched children from the United States. Multiple regression analysis provided evidence that age had the strongest predictive value for the VMI and VP skills. In addition, near visual acuity was weakly associated with performance in the VMI and the visual discrimination and spatial relationships subtests of the TVPS, accounting for a limited proportion of the intersubject variability (R < 3%; p < 0.001). CONCLUSIONS: Hong Kong preschoolers outperformed their US peers in the VMI and visual memory/spatial relationships of TVPS subtests, perhaps attributed to greater exposure to such material during their preschool home education. This study provided normality data for VMI and four subtests of the TVPS for Hong Kong Chinese preschool children as a reference for future studies.

BACKGROUND: Dobutamine stress echocardiography (DSE) suffers from high interobserver and inter-institution variability in the diagnosis of myocardial ischemia. Therefore, we developed a three-dimensional (3D) analysis tool that makes it possible to anatomically align 3D rest and stress data systematically, to generate optimal, nonforeshortened standard anatomical cross sections and to analyse the images synchronized and side-by-side. AIM OF THE STUDY: To investigate whether this 3D analysis tool could improve interobserver agreement on myocardial ischemia during 3D DSE. METHODS: The study comprised 34 consecutive patients with stable chest pain who underwent both noncontrast and contrast 3D DSE. Two observers scored segmental wall motion using a conventional analysis and the novel analysis with the new 3D tool. RESULTS: The two observers agreed on the presence or absence of myocardial ischemia in 81 of 102 coronary territories (agreement 79%, kappa (kappa) 0.28) during noncontrast 3D imaging and 92 of 102 coronary territories (agreement 90%, kappa 0.65) during contrast-enhanced 3D imaging. With the new 3D analysis software these numbers improved to 98 of 102 coronary territories (agreement 96%, kappa 0.69) during noncontrast 3D imaging and 98 of 102 coronary territories (agreement 96%, kappa 0.82) during contrast-enhanced 3D imaging. CONCLUSION: The use of a 3D DSE analysis tool improves interobserver agreement for myocardial ischemia both for noncontrast and contrast images.
