/Objectives : Multisensory inputs generate a common gravity-reference frame, but just the otoliths sense the gravity vector. Graviception is frequently assessed by setting a luminous line to the subjective visual vertical (S.V.V.). Population aging and diabetes prevalence, with insufficient physical activity, imply the need to ponder these factors in clinical assessments. This study aimed to assess S.V.V....

Discussion
Signed responses from readers of the wire.
Audiologists and balance specialists should be aware that age and diabetes status may affect subjective visual vertical test norms; using age-matched and diabetes-stratified reference values when interpreting SVV results would improve diagnostic accuracy.
Establishing age- and diabetes-stratified norms for the subjective visual vertical test refines the diagnostic precision of a commonly used vestibular assessment tool.
- 01SVV (subjective visual vertical) accuracy and precision were examined across adult age groups.
- 02Both diabetic and non-diabetic adults were included, allowing direct comparison.
- 03Age-related and diabetes-related changes in otolith function may affect SVV test interpretation.
- 04Findings could influence normative reference ranges used in vestibular clinics.
- 05Published in Diagnostics (PMID 42510008).
SVV accuracy and precision vary according to age in adults.
