Insights

Joint hypermobility in children does not appear linked to neurodevelopmental issues. This study found no causal relationship between joint hypermobility and developmental delays in school-aged children.

Area of Science:

  • Pediatric neurology
  • Developmental pediatrics
  • Orthopedics

Background:

  • Joint hypermobility is often associated with motor developmental delays in infancy.
  • The relationship between joint hypermobility and neurodevelopmental outcomes in older children requires further investigation.

Purpose of the Study:

  • To assess the association between joint hypermobility and neurodevelopmental status in school-aged children.
  • To determine if joint hypermobility is causally related to neurodevelopmental dysfunctions in children.

Main Methods:

  • Assessed 320 first- and second-grade elementary students and 110 special education students for joint hypermobility.
  • Compared neurologic status and performance on verbal and eye-hand coordination tasks with age- and sex-matched controls.

Main Results:

  • Joint hypermobility was identified in 12.4% of regular education students and 6.4% of special education students.
  • No significant differences were found in neurologic status or coordination tasks between hypermobile children and controls.

Conclusions:

  • Joint hypermobility and neurodevelopmental dysfunctions in school-aged children do not appear to be causally related.
  • The maturational trajectories of joint hypermobility and neurodevelopmental status seem distinct.

Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
Movement Joints in Buildings01:27

Movement Joints in Buildings

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...
Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
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.
Learning Disabilities01:25

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
Dyslexia
Dyslexia is a...
