Cross-Sectional Research01:50

Cross-Sectional Research

12.7K
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...

Finding Volume Using Cross-Sectional Area

96
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...

Profile Leveling and Cross Sections

1.7K
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...

Spinal Cord: Cross-sectional Anatomy

4.9K
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.
Gray Matter and its Components
Central to the gray matter is...

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Summary

Radiographic measurements of the lumbar spine, including lumbar lordosis, do not correlate with chronic low back pain (CLBP) intensity. These spinal measurements are not recommended for managing CLBP.

Area of Science:

  • Orthopedics
  • Radiology
  • Pain Management

Background:

  • Chronic low back pain (CLBP) is a prevalent condition with multifactorial causes.
  • Radiographic assessment of spinal alignment, particularly in the sagittal plane, is sometimes considered in evaluating CLBP.
  • Lumbar lordosis, sacral inclination, and lumbosacral disc angle are key sagittal parameters.

Purpose of the Study:

  • To investigate the correlation between radiographic sagittal lumbosacral spinal parameters and chronic low back pain (CLBP).
  • To determine if specific spinal curvatures (hypo- or hyperlordosis) are associated with increased CLBP intensity.

Main Methods:

  • A cross-sectional analysis of standing lateral lumbar spine radiographs from 352 CLBP patients.
  • Measurement of lumbar lordosis, lumbosacral disc angle, and sacral inclination.
  • Correlation analysis with baseline variables (pain intensity, age, sex) and regression analysis for lordosis effects.

Main Results:

  • No significant correlation was found between spinal angles and CLBP intensity or age.
  • A weak but statistically significant correlation existed between spinal measurements and sex.
  • Neither hypo- nor hyperlordosis was associated with greater CLBP intensity.

Conclusions:

  • Radiographic sagittal lumbosacral spinal measurements, including lumbar lordosis, do not correlate with CLBP intensity.
  • These radiographic parameters are not recommended for guiding pain management strategies in CLBP patients.
