Insights

Children with developmental coordination disorder (DCD) show delayed skeletal development and reduced physical activity participation. Lower intensity in activity participation is linked to this skeletal delay in children with DCD.

Area of Science:

  • Pediatric Development
  • Motor Control
  • Growth and Maturation

Background:

  • Developmental Coordination Disorder (DCD) affects motor skills in children.
  • Skeletal maturity and physical activity participation are crucial for child development.
  • Understanding the interplay between DCD, skeletal development, and activity is important.

Purpose of the Study:

  • Compare skeletal maturity and activity patterns in children with and without DCD.
  • Investigate the association between activity participation and skeletal development in children with DCD.

Main Methods:

  • Recruited 33 children with DCD and 30 typically developing children.
  • Assessed skeletal maturity using the Sunlight BonAge system.
  • Evaluated motor ability with the Movement Assessment Battery for Children-2 (MABC-2) and participation using the Children Assessment of Participation and Enjoyment.

Main Results:

  • Children with DCD exhibited delayed skeletal development and lower motor ability scores.
  • DCD group showed less intense participation in physical activities compared to controls.
  • Activity participation intensity significantly correlated with delayed skeletal development in children with DCD, explaining 28% of the variance.

Conclusions:

  • Pre-pubertal children with DCD experience delayed skeletal development.
  • Limited intensity of physical activity participation is a potential contributing factor to skeletal development delay in DCD.

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
The Functions of the Skeletal System01:22

The Functions of the Skeletal System

The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
