Insights

General movements (GMs) assessed in infancy show higher sensitivity for detecting motor problems in the fidgety period compared to the writhing period. However, the specificity of GMs for predicting later motor skills remains low.

Area of Science:

  • Developmental Pediatrics
  • Neuroscience
  • Motor Control

Background:

  • Early identification of children at high risk for cerebral palsy is established.
  • Predicting minor motor deficits in early childhood remains a challenge.

Purpose of the Study:

  • To investigate the correlation between the quality of general movements (GMs) from term to 20 weeks postterm and motor competence at 5-6 years of age.
  • To assess the predictive value of GMs for later motor development in preterm infants.

Main Methods:

  • 45 preterm infants were assessed using Prechtl's general movements (GMs) method.
  • Motor competence was evaluated using the Movement Assessment Battery for Children (M-ABC) between 5 and 6 years of age.
  • Correlations between GM quality and M-ABC scores were analyzed.

Main Results:

  • During the writhing period, GM sensitivity for detecting motor problems ranged from 0.67 (manual dexterity) to 0.92 (balance).
  • During the fidgety period, GM sensitivity was higher, reaching 1.00 for total impairment, manual dexterity, and ball skills.
  • Specificity of GMs for predicting later motor abilities was low at both term (0.24) and 3 months corrected age (0.21).

Conclusions:

  • General movements (GMs) demonstrate increased sensitivity in identifying motor problems during the fidgety period compared to the writhing period.
  • The specificity of GMs in predicting later motor abilities at term and fidgety age is limited.

5-Number Summary

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

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,...

The Movement of Organelles and Vesicles

In eukaryotic cells,  cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Relative Velocity in One Dimension

The understanding of the concept of reference frames is essential to discuss relative motion in one or more dimensions. When we say that an object has a certain velocity, we must state the velocity with respect to a given reference frame. In most examples, this reference frame has been Earth. For instance, if a statement reads that a person is sitting in a train moving at 10 m/s east, then it implies that the person on the train is moving relative to the surface of Earth at this velocity,...

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...
