Changes in the Appendicular Skeleton with Age

2.1K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Introduction to Developmental Psychology

393
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Signs of Puberty

509
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Nature and Nurture

20.6K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Area of Science:

  • Developmental Pediatrics
  • Biomechanics
  • Motor Control

Background:

  • Typical gait development is crucial for effective physical therapy interventions for gait disorders.
  • Understanding the developmental trajectory of straight gait is essential for clinical applications.

Purpose of the Study:

  • To investigate the developmental changes in straight gait control mechanisms in children.
  • To quantify straight gait using novel indices and analyze their relationship with age and gait variables.

Main Methods:

  • An experimental study involving 90 participants (76 children, 14 adults) across different age groups.
  • Development of two indices, extrapolated center of mass goal index (XCOMG) and actual progress index (XCOMP), to quantify straight gait.
  • Stepwise multiple regression analysis to identify significant gait variables influencing XCOMG and XCOMP.

Main Results:

  • Both XCOMG and XCOMP decreased with age, being significantly higher in younger children (3-4 and 5-6 years) compared to adults.
  • Step velocity, step width, and coefficient of variation (CV) of step width were key predictors for XCOMG.
  • Symmetry index of step time, step width, and CV of step width were key predictors for XCOMP.
  • Meandering gait was more prominent in younger children, with adult-like straight gait achieved by age 7.

Conclusions:

  • Pace and stability influence the ability to walk towards a target (XCOMG).
  • Stability and symmetry are important for maintaining a straight path (XCOMP).
  • The developed indices (XCOMG, XCOMP) can be utilized by physical therapists to assess straight gait ability in children.
