Abstract

OBJECTIVES: To determine the incidence of nonorganic sway patterns on computerized dynamic posturography (CDP) among patients with potential secondary gain compared with patients without any obvious secondary gain. METHODS: A retrospective chart review of 100 patients who underwent clinical evaluation, audiometry, electronystagmography, and CDP was undertaken. Group 1 consisted of 50 patients who were randomly selected from a group who had pending lawsuits, worker's compensation claims, or disability claims. Group 2 consisted of 50 randomly selected patients who had no pending legal status, worker's compensation claims, or disability claims. Previously published criteria for nonorganic sway patterns were then applied to each group. Statistical analysis was performed. RESULTS: The average age of group 1 patients was 43.8 years compared with 63.2 years for group 2 patients (P < 0.0001). Among group 1 patients 50% had normal audiovestibular evaluations compared with only 4% of group 2 patients (P < 0.0001). Nonorganic sway patterns were found in 76% of group 1 patients, but only in 8% of group 2 patients (P < 0.0001). CONCLUSION: Patients who have the potential for secondary gain are generally younger and have a much higher prevalence of normal audiovestibular evaluations and a much higher prevalence of nonorganic sway patterns on CDP. A high degree of clinical suspicion should be maintained when evaluating the dizzy patient who has a pending lawsuit, worker's compensation claim, or disability claim.
