Disorder of Water Balance01:29

Disorder of Water Balance

2.4K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...

Disorders of Acid-Base Balance01:29

Disorders of Acid-Base Balance

1.9K
The human body maintains a precise pH range of arterial blood between 7.35 and 7.45. Deviations result in either acidosis (pH < 7.35) or alkalosis (pH > 7.45). These conditions are further classified as respiratory or metabolic disorders based on their underlying cause.
Respiratory Acidosis and Alkalosis
Respiratory acidosis occurs due to an increase in the partial pressure of carbon dioxide PCO2 in the blood. It often arises from shallow breathing or impaired gas exchange caused by...

Treatment Strategies for Psychological Disorders01:24

Treatment Strategies for Psychological Disorders

756
Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

Coordination Number and Geometry02:57

Coordination Number and Geometry

19.0K
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Coordination Compounds and Nomenclature

26.5K
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Lattice Centering and Coordination Number02:33

Lattice Centering and Coordination Number

11.5K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
Types of Unit Cells
Imagine taking a large number of identical...

Summary
This summary is machine-generated.

Children with Developmental Coordination Disorder (DCD) use less efficient movement strategies than typically developing (TD) children. Even after practice, most TD children adopt effective strategies, while few with DCD do.

Area of Science:

  • Motor Control
  • Developmental Psychology
  • Kinesiology

Background:

  • Developmental Coordination Disorder (DCD) affects motor skill acquisition.
  • Understanding movement strategies is crucial for intervention.
  • The Wii Fit platform offers a novel tool for motor task analysis.

Purpose of the Study:

  • To analyze and differentiate movement control strategies in children with and without DCD.
  • To investigate changes in movement strategies over time and with practice.
  • To correlate movement strategies with task performance and quality.

Main Methods:

  • Video-observation tool to score body part movements during a Wii Fit slalom task.
  • Two-step cluster analysis to identify distinct movement strategies.
  • Comparison of strategies between children with DCD (n=28) and typically developing (TD) children (n=15).

Main Results:

  • Two distinct movement strategies were identified and validated.
  • Both groups showed initial differences and changes toward more successful strategies over time.
  • The more efficient strategy was prevalent in the majority of TD children but only a small subset of children with DCD.

Conclusions:

  • Children with DCD exhibit less efficient movement strategies compared to TD peers.
  • Practice improves strategy efficiency in both groups, but to a different extent.
  • Movement strategy analysis provides insights into motor deficits in DCD.
