    纸质或IT工具可用于远程康复模式,以提高患有发育性阅读障碍(DD)的儿童的技能,寻求提高阅读速度并减少错误。远程康复是提供远程治疗,患者在远程监护下在熟悉的环境中自主工作,通过电信手段,一个专家操作员。通过远程康复,患有DD的儿童可以在专科诊所外接受治疗,在家里或学校,通过互联网连接,并通过先进的技术平台。这些程序允许与家人充分沟通,治疗强度,练习的自适应,和儿童参与;这些因素对于高干预效果至关重要。最近的研究支持了DD儿童远程康复阅读的有效性,一些研究报告远程和面对面方法在疗效上没有差异。然而,关于远程康复所需的程序和方法,还有许多要点有待澄清,与其有效性相关的变量(例如,训练强度和儿童神经心理学特征的影响),以及不同远程治疗路径的比较有效性。本文对这些方面进行了讨论。
    Paper-based or IT tools can be used in telerehabilitation mode to improve the skills of children with developmental dyslexia (DD), seeking to increase reading speed and reduce errors. Telerehabilitation is the provision of remote treatments in which the patient works autonomously in a familiar environment under the remote monitoring, through telecommunication means, of an expert operator. Through telerehabilitation, children with DD can receive treatments outside the specialist clinic, at home or school, via internet connections, and through advanced technological platforms. These procedures allow adequate communication with the family, intensity of treatment, self-adaptivity of exercises, and child engagement; these factors are crucial for a high intervention efficacy. Recent studies have supported the effectiveness of the telerehabilitation of reading in children with DD, with some studies reporting no differences in efficacy between remote and in-person methods. Nevertheless, many points remain to be clarified about the procedures and methods required by telerehabilitation, the variables linked to its effectiveness (e.g., the impact of the intensity of the training and the neuropsychological profile of the child), and the comparative validity of different tele-treatment paths. These aspects are discussed in the present paper.

    尽管它对日常运作很重要,在发展性阅读障碍中推理不足。当前的研究调查了Wason选择任务中的言语演绎推理,以前没有在阅读障碍研究中使用,尽管它已经建立了血统。推理规则被操纵,条件规则在所呈现的逻辑值中有所不同。还操纵了单词术语的单词频率和可成像性。26名患有阅读障碍的成年人和31名没有阅读障碍的成年人完成了Wason选择任务问题。在推理准确性或完成时间方面没有发现组差异。然而,当使用规则类型进行推理时,参与者是最准确的,“如果p,则不是q\",并且使用规则类型\"Ifpthenq\"最不准确。当单词术语高度可想象但具有平均单词频率时,也可以正确回答更多的试验。这些发现与一般推理文献一致。阅读障碍状态不与规则类型或单词术语类型交互。该研究通过测试阅读障碍中的言语演绎推理来扩展先前的研究,强调可想象性在促进所有人推理性能方面的作用,无论是否存在阅读障碍。考虑了对教材设计的影响。
    Despite its importance to everyday functioning, reasoning is underexplored in developmental dyslexia. The current study investigated verbal deductive reasoning on the Wason selection task, not previously used in dyslexia research despite its well-established pedigree. Reasoning rule was manipulated, with the conditional rules varying in the logical values presented. The word frequency and imageability of the word terms was also manipulated. Twenty-six adults with dyslexia and 31 adults without dyslexia completed Wason selection task problems. No group difference in reasoning accuracy or completion time was found. However, the participants were most accurate when reasoning with the rule type \"If p, then not q\" and least accurate with the rule type \"If p then q\". More trials were also answered correctly when the word terms were highly imageable but of average word frequency. These findings are in line with the general reasoning literature. Dyslexia status did not interact with either rule type or word term type. The study expands upon previous research by testing verbal deductive reasoning in dyslexia, highlighting the role of imageability in facilitating reasoning performance for all, regardless of the presence or absence of dyslexia. Implications for the design of educational materials are considered.

    发展性阅读障碍的特点是学习阅读困难,影响认知并导致学校失败。对发展性阅读障碍儿童的干预措施侧重于提高语言能力(拼读,正交和形态学指令),但是发展性阅读障碍伴随着各种各样的感觉运动障碍。这项研究的目的是研究本体感觉干预对发育性阅读障碍儿童的阅读表现和眼球运动的影响。19名被诊断患有发育性阅读障碍的儿童被随机分配到常规言语治疗(ST)或本体感受和言语干预(PSI),他们接受了通常的言语治疗和本体感觉干预,旨在纠正他们的感觉运动障碍(棱镜眼镜,口腔神经刺激,鞋垫和呼吸说明)。在干预前和干预后(9个月后)测量无声阅读表现和眼球运动。在PSI组中,阅读性能提高,眼球运动更流畅,更快,达到与具有典型阅读表现的儿童相似的值。对书面文字的认可度也有所提高,表示更好的词汇访问。这些结果表明,PSI可能是改善发育性阅读障碍儿童阅读的有价值的工具。
    Developmental dyslexia is characterized by difficulties in learning to read, affecting cognition and causing failure at school. Interventions for children with developmental dyslexia have focused on improving linguistic capabilities (phonics, orthographic and morphological instructions), but developmental dyslexia is accompanied by a wide variety of sensorimotor impairments. The goal of this study was to examine the effects of a proprioceptive intervention on reading performance and eye movement in children with developmental dyslexia. Nineteen children diagnosed with developmental dyslexia were randomly assigned to a regular Speech Therapy (ST) or to a Proprioceptive and Speech Intervention (PSI), in which they received both the usual speech therapy and a proprioceptive intervention aimed to correct their sensorimotor impairments (prism glasses, oral neurostimulation, insoles and breathing instructions). Silent reading performance and eye movements were measured pre- and post-intervention (after nine months). In the PSI group, reading performance improved and eye movements were smoother and faster, reaching values similar to those of children with typical reading performance. The recognition of written words also improved, indicating better lexical access. These results show that PSI might constitute a valuable tool for reading improvement children with developmental dyslexia.

    这项研究旨在研究基于视觉实践的职业治疗(VPOT)计划对发育性阅读障碍(DD)儿童的阅读和运动技能的影响。42名儿童被纳入研究。此外,在VPOT之前,对参与者应用了朗读和阅读理解测试2(ORSRC-2)和Bruininininks-Oseretsky运动能力测试2-简短表格(BOT2-BF)。根据研究设计,VPOT被应用于每周两个疗程,为期8周。在此期间,B组为对照组。在这八周结束时,对两组进行评估测试.然后,A组为对照组,B组为干预组,并将VPOT应用于B组。在另外8周结束时,对两组进行了第三次评估测试.当检查最终的ORSRC-2结果时,VPOT被认为是提高阅读技能的有效计划。此外,当检查最终的BOT2-BF结果时,确定VPOT可有效改善运动技能(p<0.05)。我们认为,重要的是进行全面的研究,例如VPOT计划,以解决DD儿童的身体和学习活动中的问题。
    This study aimed to examine the effects of a visual praxis-based occupational therapy (VPOT) programme on reading and motor skills for children with developmental dyslexia (DD). Forty-two children were included in the study. Additionally, before VPOT, the Reading-Aloud and Reading-Comprehension Test 2 (ORSRC-2) and the Bruininks-Oseretsky Motor-Proficiency-Test-2-Brief Form (BOT2-BF) were applied to the participants. According to the study design, VPOT was applied to two sessions per week for 8 weeks to group A. During this period, group B was accepted as the control group. At the end of these 8 weeks, evaluation tests were applied to both groups. Then, group A was defined as the control group and Group B as the intervention group, and VPOT was applied to Group B. At the end of another 8 weeks, evaluation tests were applied to both groups for the third time. When the final ORSRC-2 results were examined, VPOT was found to be an effective programme for improving reading skills. Additionally, when the final BOT2-BF results were examined, VPOT was determined to be effective in improving motor skills (p < 0.05). We believe that it is important to carry out comprehensive studies such as the VPOT programme to solve problems in the physical and learning activities of children with DD.

    目的:患有阅读障碍的个体感知和利用听觉输入不足的统计特征。本研究调查了受影响的儿童是否也从重复上下文音调作为后续语音处理的感知锚中受益较少。
    方法:在事件相关电位研究中,患有阅读障碍(n=21)和没有阅读障碍(n=20)的11岁儿童听到了音节对,第一个音节接收恒定音高(锚)或可变音高(无锚),而第二个音节在不同条件下是相同的。
    结果:有和没有阅读障碍的儿童对恒定音高和可变音高第一音节的听觉P2反应较小,而仅对照儿童另外表现出较小的N1和较快的P1反应。这表明阅读障碍中锚重复的自动处理较少。对于第二个音节,两组在锚定后的P2反应都比无锚定第一音节快,但只有对照组额外显示较小的P2反应。
    结论:有和没有阅读障碍的儿童在锚定效应方面表现出差异。虽然两组似乎在上下文重复后对言语刺激的关注较少,患有阅读障碍的儿童在声学锚的语音处理中显示出较少的促进作用。
    结论:语言领域锚定的改变可能会导致阅读障碍患者难以建立长期的言语表征。
    OBJECTIVE: Individuals with dyslexia perceive and utilize statistical features in the auditory input deficiently. The present study investigates whether affected children also benefit less from repeating context tones as perceptual anchors for subsequent speech processing.
    METHODS: In an event-related potential study, eleven-year-old children with dyslexia (n = 21) and without dyslexia (n = 20) heard syllable pairs, with the first syllable either receiving a constant pitch (anchor) or variable pitch (no-anchor), while second syllables were identical across conditions.
    RESULTS: Children with and without dyslexia showed smaller auditory P2 responses to constant-pitch versus variable-pitch first syllables, while only control children additionally showed smaller N1 and faster P1 responses. This suggests less automatic processing of anchor repetitions in dyslexia. For the second syllables, both groups showed faster P2 responses following anchor than no-anchor first syllables, but only controls additionally showed smaller P2 responses.
    CONCLUSIONS: Children with and without dyslexia show differences in anchor effects. While both groups seem to allocate less attention to speech stimuli after contextual repetitions, children with dyslexia display less facilitation in speech processing from acoustic anchors.
    CONCLUSIONS: Altered anchoring in the linguistic domain may contribute to the difficulties of individuals with dyslexia in establishing long-term representations of speech.

    语音幅度包络携带语音清晰度所需的重要声学信息,并包含感觉线索(幅度上升时间,ARTs)在感觉节律感知和神经语音编码中起关键作用。通过时间抽样理论,儿童对ART的敏感性的个体差异与儿童跨语言的语音处理技能的发展有关。ARTs的处理障碍也是阅读障碍儿童的特征。然而,不同的研究采用了不同的ART任务,在不同的语言中,在不同的年龄。这里,我们比较了三种常用的ART任务的灵敏度(基于合成音节,正弦音调,和语音噪声)在对有或没有阅读障碍的英语儿童的纵向研究中。儿童辨别频率上升的能力,持续时间,强度也进行了测试。所有3项任务中的ART歧视均显着相互关联,但是在不同的年龄,不同的ART任务与语音和素养有不同的关系。特别是,经常使用的正弦音调和语音噪声ART任务在年龄较大的儿童中显示出更高的灵敏度,而合成音节任务(/ba/rise)在年幼儿童中显示出更高的敏感性。对频率上升的敏感性也与不同年龄的语音和读写能力有关。数据是根据发展性阅读障碍的时间抽样理论进行解释的。
    The speech amplitude envelope carries important acoustic information required for speech intelligibility and contains sensory cues (amplitude rise times, ARTs) that play a key role in both sensory rhythm perception and neural speech encoding. Individual differences in children\'s sensitivity to ARTs have been related to the development of children\'s phonological processing skills across languages by the Temporal Sampling theory. Impaired processing of ARTs also characterises children with dyslexia. However, different ART tasks have been employed in different studies, in different languages, and at different ages. Here, we compare the sensitivity of three frequently used ART tasks (based on synthetic syllables, sine tones, and speech-shaped noise) in a longitudinal study of English-speaking children with and without dyslexia. Children\'s ability to discriminate rising frequency, duration, and intensity was also tested. ART discrimination in all 3 tasks was significantly inter-related, but different relations to phonology and literacy were found for different ART tasks at different ages. In particular, the often-used sine tone and speech-shaped noise ART tasks showed greater sensitivity in older children, while the synthetic syllable task (/ba/ rise) showed greater sensitivity in younger children. Sensitivity to rising frequency was also related to phonology and literacy across ages. The data are interpreted with respect to the Temporal Sampling theory of developmental dyslexia.

    BACKGROUND: Dyslexia is one of the most common learning disabilities. It poses challenges in reading skills development and can have a lasting impact in other areas of learning.
    OBJECTIVE: To investigate the prevalence of developmental dyslexia among primary school children aged 6-13 in Arab countries, and to explore associations with gender and residency.
    METHODS: Following the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines, we included studies up to December 2023 that were found in English and Arabic research database searches. Random-effects proportional meta-analyses determined the prevalence of dyslexia in Arab countries, with a direct comparison between girls and boys using odds ratios.
    RESULTS: The meta-analysis included 18 studies with 30,243 participants: eight studies (44 %) from Egypt, four (22 %) from Saudi Arabia, and six (34 %) from other Arab countries. The pooled prevalence of dyslexia for children aged 6-13 in these studies was 11 %. The odds ratio for girls vs. boys was 0.85 (95 %). Geographical variations were notable, with eight studies (44 %) from Asia and ten (56 %) from Africa. Eight studies (44 %) were from the Gulf region, while ten (56 %) were from non-Gulf region. Prevalence of dyslexia was significantly higher in Arab countries in Asia (24 %) than in Africa (12 %), and the prevalence in non-Gulf countries was 13 % which was nearly half in comparison to Gulf countries (24 %).
    CONCLUSIONS: The prevalence rates of dyslexia in primary school children varies across the Arab world, with higher rates among boys, Arab countries in Asia, and Gulf countries. Further research is needed to include both genders and standardized diagnostics across more Arab countries to understand and address dyslexia effectively.

    40名儿科患者(67.5%的男孩和32.5%的女孩,平均年龄:11.02±2.53岁,范围:6-15岁)将DD与40名年龄和性别匹配的健康参与者进行牙齿错牙合的患病率比较,正畸参数,和超功能习惯。牙科检查由正畸医生进行。
    患有DD的儿科患者的AngleIII类错牙合的患病率明显更高(22.5%vs.5.0%,P=0.024),深咬伤(27.5%vs.7.5%,P=0.019),中线偏差(55.0%与7.5%,P<0.0001),中线舒张(32.5%与7.5%,P=0.010),磨损方面(92.5%与15.0%,P<0.0001),自我报告夜间磨牙(82.5%vs.7.5%,P<0.0001),咬指甲(35.0%vs.0.0%,P<0.0001),和非典型吞咽(85.0%vs.17.5%,P<0.0001)与健康对照组相比。
    患有DD的儿科患者表现出较高的III类错牙合患病率,较大的正畸垂直和横向差异,和功能异常活动的发生率。临床医生和牙医应意识到阅读障碍儿童表现出错牙合的脆弱性,并鼓励早期评估和多学科干预。
    UNASSIGNED: The study aimed to assess the prevalence of dental malocclusion, orthodontic parameters, and parafunctional habits in children with developmental dyslexia (DD).
    UNASSIGNED: Forty pediatric patients (67.5% boys and 32.5% girls, mean age: 11.02 ± 2.53 years, range: 6-15 years) with DD were compared with 40 age- and sex-matched healthy participants for prevalence of dental malocclusion, orthodontic parameters, and parafunctional habits. Dental examinations were performed by an orthodontist.
    UNASSIGNED: Pediatric patients with DD exhibited a significantly higher prevalence of Angle Class III malocclusion (22.5% vs. 5.0%, P = 0.024), deep bite (27.5% vs. 7.5%, P = 0.019), midline deviation (55.0% vs. 7.5%, P < 0.0001), midline diastemas (32.5% vs. 7.5%, P = 0.010), wear facets (92.5% vs. 15.0%, P < 0.0001), self-reported nocturnal teeth grinding (82.5% vs. 7.5%, P < 0.0001), nail biting (35.0% vs. 0.0%, P < 0.0001), and atypical swallowing (85.0% vs. 17.5%, P < 0.0001) compared to that in healthy controls.
    UNASSIGNED: Pediatric patients with DD showed a higher prevalence of Class III malocclusion, greater orthodontic vertical and transverse discrepancies, and incidence of parafunctional activities. Clinicians and dentists should be aware of the vulnerability of children with dyslexia for exhibiting malocclusion and encourage early assessment and multidisciplinary intervention.

    背景:发展性阅读障碍,一种复杂的神经发育障碍,不仅影响儿童的学习成绩,而且还与医疗费用的增加有关,就业率较低,降低了生产力。阅读障碍的发病机制尚不清楚,一般认为是由遗传和环境因素重叠引起的。目前缺乏系统地探索阅读障碍发展中环境化合物暴露与易感基因之间的密切关系,但很有必要。
    方法:在本研究中,我们系统地汇编了131个公开报道的来自DisGeNet的阅读障碍易感基因,OMIM,和GeneCards数据库。比较毒性基因组学数据库数据库用于探索易感基因与95种环境化合物之间的重叠,包括金属,持久性有机污染物,多环芳烃,和杀虫剂。在观察/期望比>1和通过超几何概率检验获得的相应P值中,考虑了对阅读障碍风险基因的化学偏见。
    结果:我们的研究发现,每种化学物质靶向的阅读障碍风险基因的数量从1到109不等。共有35种化学物质参与了与阅读障碍相关基因的化学反应,具有从1.147(阿特拉津)到66.901(二苯并(a,h)芘)。
    结论:结果表明,阅读障碍相关基因与某些化学反应有关。然而,这些发现是探索性的,需要进一步研究涉及动物或细胞实验。
    BACKGROUND: Developmental dyslexia, a complex neurodevelopmental disorder, not only affects children\'s academic performance but is also associated with increased healthcare costs, lower employment rates, and reduced productivity. The pathogenesis of dyslexia remains unclear and it is generally considered to be caused by the overlap of genetic and environmental factors. Systematically exploring the close relationship between exposure to environmental compounds and susceptibility genes in the development of dyslexia is currently lacking but high necessary.
    METHODS: In this study, we systematically compiled 131 publicly reported susceptibility genes for dyslexia sourced from DisGeNET, OMIM, and GeneCards databases. Comparative Toxicogenomics Database database was used to explore the overlap between susceptibility genes and 95 environmental compounds, including metals, persistent organic pollutants, polycyclic aromatic hydrocarbons, and pesticides. Chemical bias towards the dyslexia risk genes was taken into account in the observation/expectation ratios > 1 and the corresponding P value obtained by hypergeometric probability test.
    RESULTS: Our study found that the number of dyslexia risk genes targeted by each chemical varied from 1 to 109. A total of 35 chemicals were involved in chemical reactions with dyslexia-associated genes, with significant enrichment values (observed/expected dyslexia risk genes) ranging from 1.147 (Atrazine) to 66.901 (Dibenzo(a, h)pyrene).
    CONCLUSIONS: The results indicated that dyslexia-associated genes were implicated in certain chemical reactions. However, these findings are exploratory, and further research involving animal or cellular experiments is needed.

    背景:形态意识(MA)缺陷与中国发展性阅读障碍(DD)密切相关。然而,关于中国DD儿童MA缺陷背后的白质底物知之甚少。
    方法:在目前的研究中,招募了34名患有DD的中国儿童和42名典型发育(TD)儿童,以完成MA的扩散磁共振成像扫描和认知测试。我们进行了线性回归来检验MA和DTI指标之间的相关性,与MA相关的束的结构异常,以及分组DTI指标对MA的交互作用。
    结果:首先,MA与右枕骨-额叶下束(IFO)和下纵肌(ILF)显著相关,双侧丘脑-枕骨(T_OCC)和左弓状束(AF);第二,与TD儿童相比,中国患有DD的儿童在右IFO和T_OCC中具有较低的轴向扩散系数(AD);第三,各组中右IFO和MA的度量(各向异性分数(FA)和径向扩散率(RD))之间存在显着相互作用。在DD儿童中,右IFO的FA和RD与MA显着相关,而在TD儿童中没有。
    结论:结论:与TD儿童相比,中国DD儿童不仅在腹侧束(右IFO)而且在视觉空间束(右T_OCC)都有轴突变性,这与他们的MA缺陷有关。中国MA不仅涉及腹侧,还有视觉空间通路和背道。
    BACKGROUND: Morphological awareness (MA) deficit is strongly associated with Chinese developmental dyslexia (DD). However, little is known about the white matter substrates underlying the MA deficit in Chinese children with DD.
    METHODS: In the current study, 34 Chinese children with DD and 42 typical developmental (TD) children were recruited to complete a diffusion magnetic resonance imaging scan and cognitive tests for MA. We conducted linear regression to test the correlation between MA and DTI metrics, the structural abnormalities of the tracts related to MA, and the interaction effect of DTI metrics by group on MA.
    RESULTS: First, MA was significant related to the right inferior occipito-frontal fascicle (IFO) and inferior longitudinal fsciculus (ILF), the bilateral thalamo-occipital (T_OCC) and the left arcuate fasciculus (AF); second, compared to TD children, Chinese children with DD had lower axial diffusivity (AD) in the right IFO and T_OCC; third, there were significant interactions between metrics (fractional anisotropy (FA) and radial diffusivity (RD)) of the right IFO and MA in groups. The FA and RD of the right IFO were significantly associated with MA in children with DD but not in TD children.
    CONCLUSIONS: In conclusion, compared to TD children, Chinese children with DD had axonal degeneration not only in the ventral tract (the right IFO) but also the visuospatial tract (the right T_OCC) which were associated with their MA deficit. And Chinese MA involved not only the ventral tracts, but also the visuospatial pathway and dorsal tracts.
