Discussion
Signed responses from readers of the wire.
The EGV scale shows promise as a patient-reported outcome tool for vestibular symptom severity, but clinicians should await broader external validation before adopting it over established scales.
A psychometrically validated self-report scale for vestibular symptom severity could standardize patient-reported outcomes in balance disorder clinics and vestibular research.
- 01The EGV (Self-Perception of Vestibular Symptom Severity Scale) is a newly developed patient-reported outcome measure.
- 02Published in Brazilian Journal of Otorhinolaryngology (PMID 42790266).
- 03Psychometric validation included assessments of validity and reliability.
- 04Focuses on how patients themselves perceive the severity of their vestibular (balance-related) symptoms.
- 05A validated scale could improve consistency in clinical assessment and research on dizziness disorders.
The EGV scale demonstrates valid and reliable measurement of self-perceived vestibular symptom severity.
