[Evaluation of diagnosing cervical vertigo with computerized static posturography].

Area of Science:

• Biomechanics
• Neurology
• Ophthalmology

Context:

• Cervical vertigo diagnosis relies on subjective assessments.
• Objective diagnostic tools are needed to improve accuracy and clinical utility.
• Quantitative biomechanical methods offer a potential solution.

Purpose:

• To establish a quantitative biomechanics method for diagnosing cervical vertigo.
• To evaluate the clinical value of static posturography (SPG) in diagnosing cervical vertigo.
• To compare the diagnostic performance of SPG under closed-eye and open-eye conditions.

Summary:

• Static posturography (SPG) demonstrated high sensitivity (76%) and specificity (93%) for diagnosing cervical vertigo with eyes closed.
• Foreword-backward type shift orbit was identified as a key indicator in patients with cervical vertigo.
• SPG with eyes open yielded lower diagnostic accuracy (sensitivity 49.3%), indicating its limitations.

Impact:

• SPG with eyes closed provides a valid, reliable, and clinically applicable method for objective cervical vertigo diagnosis.
• The findings support the integration of SPG into clinical practice for improved diagnostic capabilities.
• Further research may refine open-eye SPG protocols or explore alternative diagnostic strategies.
