Summary
Boys with Developmental Coordination Disorder (DCD) struggle with catching, especially in lateral trials. Their coordination challenges limit their ability to perform complex catching tasks effectively.
Area of Science:
- Motor Control
- Developmental Psychology
- Pediatrics
Background:
- Developmental Coordination Disorder (DCD) affects motor skill acquisition.
- Catching is a complex motor skill influenced by coordination.
- Understanding task constraints is crucial for DCD research.
Purpose of the Study:
- To investigate catching coordination in boys with and without DCD.
- To examine the impact of task constraints (location, randomization) on catching performance.
- To identify the specific coordination deficits in boys with DCD.
Main Methods:
- 12 boys with and without DCD participated.
- Participants performed 60 catches in central and lateral locations.
- Blocked and randomized trial conditions were employed.
Main Results:
- No significant effect of randomization on catching accuracy.
- A significant Group x Location interaction revealed performance differences.
- Boys with DCD performed significantly worse in lateral catching trials.
Conclusions:
- Boys with DCD exhibit significant difficulties in lateral catching tasks.
- Grasping and positional errors were prominent in lateral trials for boys with DCD.
- Intersegmental coordination limitations appear to be a key factor in DCD-related catching deficits.

01:28Conduct 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;...
01:30Attention-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.

01:19Autism 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.

01:24Muscle Coordination and Action
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.
