Aphysiologic performance on dynamic posturography in work-related patients
Summary
Malingering suspicion in dizziness claims is not supported by this study. Aphysiologic computerized dynamic posturography (CDP) results were similar between work-related and non-work-related dizziness patients.
Area of Science:
- Neurology
- Otolaryngology
- Audiology
Background:
- Malingering is suspected in dizziness/imbalance patients with potential secondary gain (insurance/worker's compensation).
- Computerized dynamic posturography (CDP) assesses balance and can reveal non-physiologic performance.
Purpose of the Study:
- To compare the prevalence of aphysiologic CDP performance in work-related dizziness patients versus non-work-related dizziness patients.
- To investigate the association between secondary gain and non-physiologic balance test results.
Main Methods:
- Retrospective review of two groups: work-related (Group 1) and non-work-related (Group 2) dizziness patients.
- All patients underwent CDP and videonystagmography (VNG).
- CDP Sensory Organization Test summaries were scored as normal, aphysiologic, or vestibular.
Main Results:
- Aphysiologic CDP prevalence was 27% in Group 1 and 18% in Group 2; this difference was not significant.
- Vestibular dysfunction was found in 50% of aphysiologic cases in Group 1.
- VNG abnormalities were significantly higher in Group 2 (p=0.005).
Conclusions:
- The study did not confirm a higher rate of aphysiologic CDP in work-related dizziness patients.
- VNG abnormalities were noted in 50% of work-related cases with non-organic sway patterns.
- Patient complaints in work-related cases should be considered genuine, with caution in interpreting aphysiologic CDP patterns.
