“…Morgan et al [2002] looked whether dynamic posturography was able to detect informed malingerers, based on the scoring method of Cevette et al [1995] and blinded subjective clinical scoring. They investigated 2 groups of healthy subjects who both were asked to simulate a balance deficit.…”

Differentiating balance disorder patients who are malingering from those with organic balance disorders is difficult and costly. We used trunk sway measured during several stance and gait tasks in 18 patients suspected of malingering in order to differentiate these from 20 patients who had suffered unilateral vestibular loss 3 months earlier, 20 patients with documented whiplash injuries, and 34 healthy controls. Classification results ranged from 72 to 96% and were equally accurate for task or criteria variables based on 90% sway values. The tasks yielding the best discrimination were: standing with eyes closed on a foam and firm surface; standing with eyes open on a firm surface; standing on 1 leg; and walking tandem steps. The criteria yielding the best discrimination were: standing with eyes open on a firm surface; the difference between standing with eyes closed on foam and firm surfaces; the difference between walking tandem steps and standing on 1 leg with eyes open; and the difference between roll and pitch velocity when walking 8 tandem steps. We conclude that discriminating suspected malingering balance disorder patients is possible using variables or criteria based on objective measures of trunk sway during several stance and gait tasks.

“…Thus despite some doubts [see Morgan et al, 2002], sway-referenced dynamic posturography appears to be able to objectively determine a malingerer's balance performance. Nonetheless, this technique has some disadvantages.…”

It has been suggested that malingering should be suspected in patients suffering from dizziness or imbalance and who had a potential gain associated with insurance and worker's compensation claims. This study aimed to assess and compare the prevalence of aphysiologic performance on computerized dynamic posturography (CDP) in patients with the potential for secondary gain using a retrospective review of two groups of patients: work-related patients referred for dizziness and/or imbalance (Group 1) were compared against a group of patients with complaints of dizziness or imbalance, who had no history of work-related injury, or litigation procedures (Group 2). CDP and videonystagmography (VNG) were carried out in all patients. The Sensory Organization Test summaries were scored as normal, aphysiologic, or vestibular using the scoring method published by Cevette et al. in Otolaryngol Head Neck Surg 112:676-688 (1995). 24 out of 88 (27%) patients had aphysiologic CDP in Group 1 and 9 out of 51 (18%) in Group 2 but these differences were not significant (p > 0.05). Definite signs of vestibular dysfunction were found in 12 out of 24 (50%) of patients with aphysiologic performance in Group 1 although the presence of VNG abnormalities was significantly higher (p = 0.005) in Group 2. The hypothesis that the occupational group could show a significantly higher rate of aphysiologic results than a control group is not confirmed. Furthermore, VNG abnormalities were found in 50% of the work-related cases with non organic sway patterns. These results suggest that patient's complaints should be considered genuine in work-related cases and due caution exercised when evaluating aphysiologic CDP patterns.
