Insights

Infant trunk and pelvic movements differ based on motor development and attention. Eulerian Video Magnification (EVM) revealed unique movement patterns in typically developing, preterm, and cerebral palsy infants during focused attention tasks.

Area of Science:

  • Developmental Pediatrics
  • Motor Control
  • Infant Movement Analysis

Background:

  • Infant motor development is crucial for cognitive engagement.
  • Understanding trunk and pelvic movement in early sitting is key.
  • Attention influences motor control in older children and adults.

Purpose of the Study:

  • To examine infant movement during sitting using a novel video technique.
  • To compare movement patterns in typically developing (TD), preterm, and cerebral palsy (CP) infants.
  • To assess movement differences during focused attention (FA) versus non-focused attention (NFA).

Main Methods:

  • Utilized Eulerian Video Magnification (EVM) to enhance subtle trunk and pelvic movements.
  • Analyzed video recordings of infants during natural play tasks.
  • Compared movement patterns across TD, preterm, and CP infants under FA and NFA conditions.

Main Results:

  • Trunk/pelvic movement varied significantly with motor skill and attention.
  • TD and CP infants showed reduced movement during FA compared to NFA.
  • Preterm infants exhibited greater movement overall, irrespective of attention type.

Conclusions:

  • EVM provides a reliable method for analyzing hidden infant motor adjustments.
  • Reduced extraneous movement during sitting may facilitate attention.
  • Persistent excessive movement in preterm infants could impact future attentional resource allocation.

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....

Glycolysis: Pay-off Phase01:25

Glycolysis: Pay-off Phase

So far, glycolysis has cost the cell two ATP molecules and produced two small, three-carbon sugar molecules. These molecules will proceed through the second half of the pathway, and sufficient energy will be extracted to pay back the two ATP molecules used as an initial investment and produce a profit for the cell of two additional ATP molecules and two even higher-energy NADH molecules.
Step 1 - 5: Glycolysis Preparatory Phase
The first phase of glycolysis has 5 steps where the glucose is...

Typical Model Studies

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Short-distance Transport of Resources02:12

Short-distance Transport of Resources

Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Sustainable Development01:43

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Anatomical Movements00:51

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
