Summary
Establishing normal parameters for Craniocorpography (CCG) is crucial. This study defines reference values for CCG tests in healthy adults, improving diagnostic accuracy for balance disorders.
Area of Science:
- Neurology
- Biomechanics
- Vestibular System
Background:
- Normal parameter data for Craniocorpography (CCG) is limited and inconsistent.
- Existing CCG results vary significantly across different studies.
- Establishing normative data is essential for accurate clinical interpretation.
Purpose of the Study:
- To define the criteria for normal Craniocorpography (CCG) in a healthy reference population.
- To provide reliable reference values for CCG measurements.
- To enhance the diagnostic utility of CCG.
Main Methods:
- Prospective study involving 72 healthy volunteers.
- Utilized computerized measurement for Romberg and Unterberger tests.
- Statistical modeling applied for parameter estimation, assuming Gaussian distribution.
Main Results:
- Normal limits for lateral and antero-posterior oscillation established.
- Lateral sway normal limits: 9 cm (lateral), 12 cm (antero-posterior).
- Angular deviation normal limits: 59° (right), 46° (left).
Conclusions:
- A computerized method aids in precise CCG analysis.
- This study provides validated normal CCG values for a reference population.
- The findings contribute to more accurate diagnosis and monitoring of balance disorders.
