Summary
This study establishes reference values for sagittal plane posture analysis in healthy adults using computerized photogrammetry. These findings provide crucial data for future postural assessments and research.
Area of Science:
- Biomechanics
- Human Posture Analysis
- Medical Imaging
Background:
- Computerized photogrammetry has established reference values for coronal plane postural alignment.
- Sagittal plane postural alignment reference values are lacking for healthy adults.
- Accurate postural analysis is essential for identifying musculoskeletal imbalances.
Purpose of the Study:
- To propose reference values for angular measurements of sagittal plane posture in healthy adults.
- To establish a baseline for objective postural assessment using photogrammetry.
- To address the gap in sagittal plane postural data.
Main Methods:
- Systematic literature search of electronic databases (PubMed, BVS, Cochrane, Scielo, Science Direct) from 2006-2012.
- Inclusion of articles utilizing the Postural Assessment Software/Software for the Analysis of Postural (PAS/SAPO).
- Calculation of average angular values for head horizontal alignment, pelvic horizontal alignment, hip angle, and vertical body alignment.
Main Results:
- Six articles met the inclusion criteria.
- Average angular values were determined for: head horizontal alignment (51.42° ± 4.87°), pelvic horizontal alignment (-12.26° ± 5.81°), hip angle (-6.40° ± 3.86°), and vertical body alignment (1.73° ± 0.94°).
- Thoracic kyphosis and lumbar lordosis measurements were not found in the selected articles.
Conclusions:
- The proposed reference values can serve as a benchmark for future sagittal plane postural assessments.
- Consistency in anatomical landmark identification is recommended for reliable comparisons.
- Further research is needed to include thoracic kyphosis and lumbar lordosis data.

Adjusting a Traverse
477
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

Influence of Earth's Curvature and Atmospheric Refraction on Leveling
1.3K
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

Design Example: Traverse Angle Computations
453
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Methods of Obtaining Topography
550
Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...
