Summary
The subjective visual vertical (SVV) test shows good reliability for assessing spatial orientation. Normative data for static and dynamic conditions can help identify utricular dysfunction.
Area of Science:
- Neuroscience
- Vestibular System Function
- Spatial Orientation Perception
Background:
- Otoliths are crucial gravito-inertial force sensors for spatial orientation.
- The subjective visual vertical (SVV) test assesses gravitational vertical perception.
- Establishing normative data and reliability is essential for clinical SVV test use.
Purpose of the Study:
- To acquire normative data for the SVV test.
- To determine the test-retest reliability of the SVV test.
- To evaluate SVV performance in static and dynamic conditions.
Main Methods:
- A descriptive study design was employed.
- Twenty-four healthy young adults participated.
- SVV angles were measured in static and dynamic (on-axis and off-axis rotation) conditions.
Main Results:
- In healthy individuals, static and on-axis SVV were <2°.
- Unilateral centrifugation caused SVV shifts up to 11°.
- The SVV test demonstrated good test-retest reliability across all conditions.
Conclusions:
- The obtained normative SVV data may aid in diagnosing chronic utricular dysfunction.
- Using difference angles (on-axis SVV - off-axis SVV) can reduce bias and variability.
- The SVV test is reliable for static and dynamic assessments of spatial orientation.
