まとめ
この研究では、ダウン症候群(DS)児の微細運動スキル発達曲線を作成しました。初期の遅れにもかかわらず、DS児では把握および視覚運動スキルは年齢とともに改善します。
科学分野:
- 発達小児科学
- 神経発達障害
- 運動発達
背景:
- ダウン症候群(DS)児は、微細運動スキルに遅れを示すことがよくあります。
- DS児の特定と支援のためには、典型的な発達軌道を理解することが不可欠です。
研究 の 目的:
- ダウン症候群児の微細運動発達の標準成長曲線を作成する。
- 特に把握および視覚運動統合スキルを評価する。
- 早期発見と介入のためのツールを提供する。
主な方法:
- ダウン症候群児の大規模コホートの後ろ向きチャートレビュー。
- ピーボディ発達運動尺度第2版(PDMS-2)から収集されたデータ。
- 生後0歳から6歳までの児の分析。
主要な成果:
- ダウン症候群児は、典型的な発達児と比較して、微細運動および視覚運動発達に遅れが見られました。
- 把握および視覚運動の総合スコアは、年齢とともに増加しました。
- 微細運動指数と年齢の間には負の関連が観察されました。
結論:
- 開発されたダウン症候群特異的パーセンタイル曲線は、さらなる評価が必要な児の特定に役立ちます。
- これらの曲線は、DSにおける微細運動発達に影響を与える要因に関する将来の研究に役立ちます。
- このデータは、保護者が発達検査の結果を解釈し、子供の進捗状況を理解するのに役立ちます。

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Introduction to Developmental Psychology
1.3K
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Meiosis vs. Mitosis
69.2K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

Meiosis I
217.4K
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by...

Intellectual Disability
595
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
