Insights

Typical children reduce postural sway with age during sit-to-stand (STS) movements. Children with cerebral palsy (CP) do not exhibit these age-related changes in sway, indicating different postural control development.

Area of Science:

  • Pediatrics
  • Neurology
  • Biomechanics

Background:

  • Postural sway, a measure of balance, changes with age in typical development.
  • Cerebral palsy (CP) can impact motor development, potentially affecting postural control.
  • Understanding age-related changes in postural sway is crucial for assessing developmental milestones and identifying atypical development.

Purpose of the Study:

  • To investigate age-related differences in postural sway during sit-to-stand (STS) movements.
  • To compare postural sway development between typical children (TC) and children with mild CP.
  • To identify potential delays or differences in postural control development in children with CP.

Main Methods:

  • Thirty-five TC and 23 children with mild CP were grouped by age (5-6, 7-9, 10-12, 13-15 years).
  • Participants performed STS movements while standing on a force plate.
  • Anterior-posterior and medial-lateral center of pressure (CoP) displacement, area, and velocity were analyzed.

Main Results:

  • TC aged 5-6 years exhibited greater anterior-posterior CoP displacement and CoP sway area during the stabilization phase compared to those aged 10-12 years.
  • No significant age-related changes in postural sway were observed in children with mild CP.
  • This suggests a divergence in postural control maturation between TC and children with CP.

Conclusions:

  • Typical children demonstrate a reduction in postural sway during the latter stages of STS as they mature.
  • Children with CP do not show similar age-related improvements in postural sway during STS.
  • This highlights a distinct developmental trajectory of postural control in children with CP.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Standing Waves01:17

Standing Waves

Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...

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.

Modes of Standing Waves - I

A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This...

Modes of Standing Waves: II

The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....

Standing Waves in a Cavity01:28

Standing Waves in a Cavity

A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:
