Summary
Children with developmental coordination disorder (DCD) have poorer kinesthetic sensitivity than typically developing peers. This difference becomes significant and measurable in children aged seven and older.
Area of Science:
- Neuroscience
- Developmental Psychology
- Motor Control
Background:
- Developmental Coordination Disorder (DCD) affects motor skills in children.
- Kinesthetic sensitivity, the ability to sense body position and movement, is crucial for motor control.
- Limited research exists on kinesthetic sensitivity differences between DCD and typically developing (TD) children.
Purpose of the Study:
- To quantify and compare kinesthetic sensitivity in children with DCD and TD children.
- To investigate age-related differences in kinesthetic sensitivity between the two groups.
Main Methods:
- A passive motion apparatus was used to measure elbow joint extension at controlled velocities.
- Participants (30 DCD, 30 TD, aged 6-11 years) detected passive arm movements.
- Detection time was recorded as the primary measure of kinesthetic sensitivity.
Main Results:
- Children with DCD exhibited significantly lower kinesthetic sensitivity compared to TD children.
- This deficit was more pronounced in DCD children aged seven and older.
- Eleven-year-old children with DCD showed kinesthetic sensitivity comparable to seven-year-old TD children.
Conclusions:
- Children with DCD demonstrate a lag in kinesthetic sensitivity development compared to TD peers.
- Kinesthetic sensitivity deficits in DCD are significant and measurable between ages 7-11.
- These findings highlight a potential sensory-motor basis for coordination difficulties in DCD.

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.

01:15Kinematic Equations: Problem Solving
29.8K
When analyzing one-dimensional motion with constant acceleration, the problem-solving strategy involves identifying the known quantities and choosing the appropriate kinematic equations to solve for the unknowns. Either one or two kinematic equations are needed to solve for the unknowns, depending on the known and unknown quantities. Generally, the number of equations required is the same as the number of unknown quantities in the given example. Two-body pursuit problems always require two...

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.

01:24Muscle Coordination and Action
4.1K
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.

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

01:18Hierarchy of Motor Control
6.9K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
