Summary
Adolescents with concussion show increased postural sway, especially with eyes closed or on unstable surfaces. This sway correlates with symptoms like dizziness and confusion, aiding objective balance assessment.
Area of Science:
- Neuroscience and Sports Medicine
- Biomechanics and Motor Control
Background:
- Concussion in adolescents can lead to persistent balance impairments.
- Objective measures are needed to quantify these deficits in clinical settings.
Purpose of the Study:
- To quantify postural sway during various balance tasks in adolescents with concussion.
- To explore the relationship between postural sway and concussion-related symptoms.
Main Methods:
- A cross-sectional study involving 56 symptomatic adolescents (aged 13-17) within 44 days post-concussion.
- Anterior-posterior postural sway measured via lower back accelerometer during 6 static balance tasks.
- Tasks varied visual input, surface type, and foot stance; symptoms were self-reported.
Main Results:
- Postural sway was significantly greater with eyes closed versus eyes open (19.3 vs. 12.4 mG/s).
- Increased sway observed on foam surfaces or during tandem stance compared to firm surface, feet together.
- Greater sway correlated with reported dizziness and confusion at injury, and with current dizziness and headache.
Conclusions:
- Accelerometer-based postural sway measurement offers an objective method for assessing balance deficits in concussed adolescents.
- The association between sway magnitude and symptom severity highlights the importance of considering symptoms during assessment.

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

01:24Finding Volume Using Cross-Sectional Area
67
For solids whose cross-sectional areas vary in a predictable way, volume can be determined by integrating these areas along an axis perpendicular to the slices. This approach is particularly useful for polyhedral solids, where classical geometric formulas may not be immediately applicable. A tetrahedron provides a clear example of how cross-sectional integration can be applied to a three-dimensional object with continuously changing geometry.Consider a tetrahedron with height h and a base that...

01:26Profile Leveling and Cross Sections
1.6K
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

01:16Spinal Cord: Cross-sectional Anatomy
4.8K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:34Crossing Over
171.9K
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

01:30Crossing Over
6.5K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...
