Equilibrium and Balance01:15

Equilibrium and Balance

6.1K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

4.5K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

The Vestibular System01:29

The Vestibular System

38.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Summary

Motion sickness affects nearly half of schoolchildren in cars and buses. This condition is linked to poorer postural balance and reduced quality of life in children.

Area of Science:

  • Pediatric Health
  • Neuroscience
  • Human Physiology

Background:

  • Motion sickness is a common condition affecting individuals during travel.
  • Understanding its prevalence and impact on children's well-being is crucial for targeted interventions.
  • Previous research has explored motion sickness triggers, but its relationship with postural control and quality of life in school-aged children requires further investigation.

Purpose of the Study:

  • To determine the prevalence of motion sickness in schoolchildren aged 7-12 years.
  • To investigate the association between motion sickness, postural balance, and quality of life in this population.
  • To identify specific transport modes and activities associated with higher motion sickness incidence.

Main Methods:

  • A population-based cross-sectional study involving 831 schoolchildren (ages 7-12).
  • Motion sickness susceptibility was assessed using the Motion Sickness Susceptibility Questionnaire-Short (MSSQ-short).
  • Postural balance was evaluated using the Romberg test, and quality of life was measured with the Dizziness Handicap Inventory (DHI).

Main Results:

  • The prevalence of motion sickness was high: 43.4% in cars and 43.2% on buses.
  • Significant correlations were observed between MSSQ-short scores and all postural balance tests.
  • A significant association was found between motion sickness (MSSQ scores) and quality of life (modified DHI scores) across all age groups.

Conclusions:

  • Motion sickness is highly prevalent in schoolchildren, particularly during car and bus travel.
  • Impaired postural balance and reduced quality of life are associated with motion sickness in children.
  • These findings highlight the need for strategies to manage motion sickness and its consequences in pediatric populations.
