During the last 10 years, computerized dynamic posturography has yielded various patterns of sway on the sensory organization test and the motor control test that have been associated with a variety of organic balance disorders. Some aspects of performance during computerized dynamic posturography, however, are under conscious control. Voluntary movements not indicative of physiologic response to balance system stimulation can also affect computerized dynamic posturography results. Quantification of nonorganic or “aphysiologic” response patterns in normal subjects, patients, and suspected malingerers is crucial to justify use of computerized dynamic posturography for identification of physiologically inconsistent results. For this purpose the computerized dynamic posturography records of 122 normal subjects, 347 patients with known or suspected balance disorders, and 72 subjects instructed to feign a balance disturbance were critically evaluated by use of seven measurement criteria, which were postulated as indicating aphysiologic sway. Each criterion was scored with a standard calculation of the raw data in a random, blinded fashion. The results of this multicenter study show that three of the seven criteria are significantly different in the suspected “malingerer” group when compared with either the normal or patient group. The relative strength of each criterion in discerning organic from nonorganic sway provides the examiner with a measure of reliability during platform posture testing. This study demonstrates that computerized dynamic posturography can accurately identify and document nonorganic sway patterns during routine assessment of posture control.

The relationship between lifetime alcohol consumption and postural control was investigated in 35 subjects with no clinically-detectable neurologic abnormalities, using computerized dynamic posturography (CDP) procedures. The estimated total number of lifetime alcoholic drinks was positively correlated with anteroposterior sway spectral power within the 2–4 Hz and 4–6 Hz frequency bands, in three Sensory Organization Test (SOT) conditions: eyes closed with stable support surface (SOT 2), eyes open with sway-referenced support (SOT 4), and eyes closed with sway-referenced support (SOT 5). All correlations remained significant after controlling for subject age, and were increased after excluding nine drug-abusing subjects. In contrast to the strong findings for frequency-based measures, no correlation was observed using conventional amplitude-based sway measures. These results suggest that 1) alcohol consumption compromises postural control in an exposure-dependent manner, and 2) sway frequency analysis reveals pathological processes not manifested in conventional CDP measures of sway amplitude.

Vestibular Pathology

OBJECTIVE: We sought to correlate the severity of vertigo and handicap in patients with vestibular pathology according to measures of impairment. STUDY DESIGN AND SETTING: We conducted a prospective assessment of patients with dizziness by means of caloric, rotatory test, and computerized dynamic posturography to estimate impairment. Handicap and severity of vertigo were determined with specific questionnaires (Dizziness Handicap Inventory and UCLA-DQ). RESULTS: A fair relationship were found between severity of dizziness and vestibular handicap. When impairment was taken into consideration, values were still fair and only moderate for a group of patients with an abnormal caloric test as the only pathologic finding. The composite score from the sensory organization test portion of the computerized dynamic posturography is fairly correlated to severity of vertigo and handicap in the whole population of patients, but no correlation was found when they were assigned to groups of vestibular impairment. CONCLUSION: To assess vestibular impairment, the results from several tests must be taken into account. However, vestibular handicap is not solely explained with measurements of impairment and/or severity.

Soccer Training

The aim of this study was to determine the effect of regular soccer training on the balance system for young women. Computerized dynamic posturography of female footballers (n = 25) and control group (n = 50) was assessed during three tests: Sensory Organization Test, Motor Control Test, and Adaptation Test. Statistically significant differences between the groups was found in Composite Equilibrium Score with higher values, indicating better postural stability, for footballers. Regular trainees also showed better usefulness of vestibular system while maintaining balance. Weight symmetry of the lower limbs during Motor Control Test also showed statistically significant differences between the groups. This study shows that female footballers have better postural stability than their inactive peers and that regular workouts may improve the balance system.

Insight Into

The complexities of the balance system create difficulties for professionals interested in testing equilibrium function objectively. Traditionally, electronystagmography (ENG) has been used for this purpose, but it provides information on only a limited portion of the equilibrium system. Computerized dynamic posturography (CDP) is less specific than ENG, but it provides more global insight into a patient's ability to maintain equilibrium under more challenging environmental circumstances. CDP also appears to be valuable in obtaining objective confirmation of an abnormality in some dizzy patients whose ENG findings are normal. Our review of 33 patients with normal ENG results and abnormal CDP findings suggests that posturography is useful for confirming or quantifying a balance abnormality in some patients whose complaints cannot be confirmed by other tests frequently used by otologists.

We measured sway velocity using static and dynamic posturography in a group of young normal subjects and two groups of subjects older than 75 years; one older group considered their balance normal for their age, and the other reported imbalance. The latter group consisted of patients with documented peripheral and central vestibular disorders and patients with dizziness and imbalance of unknown cause. The velocity of sway was higher in older subjects than in younger subjects and in older subjects who reported imbalance than in age-matched controls. The difference was greater with dynamic posturography than with static posturography, but the posturography data provided little information about the cause of the imbalance and did not correlate with the frequency of reported falls.

Background: People with multiple sclerosis (MS) frequently have impaired postural control (balance). Psychometric properties of clinical tests of balance for individuals with MS, including the computerized dynamic posturography sensory organization test (CDP-SOT), are poorly understood. This study aimed to determine the reliability and discriminant validity of the CDP-SOT in people with MS. Methods: The CDP-SOT was performed on 30 participants with MS. A 2-week–interval, repeated-measures (sessions 1 and 2) design was implemented to investigate test-retest reliability of the CDP-SOT and the ability of the CDP-SOT to discriminate between participants with lower versus higher disability. Self-reported disability level was based on Patient-Determined Disease Steps (PDDS) scale scores: lower (PDDS scale score, 0–3; n = 17) and higher (PDDS scale score, 4–6; n = 13). Results: All six conditions of the CDP-SOT had good-to-excellent reliability (interclass correlation coefficients, 0.70–0.90) and excellent reliability for composite scores (0.90). Composite scores were significantly greater in the lower-disability group versus the higher-disability group at session 1 (70.89 vs. 48.60, P = .001) and session 2 (74.82 vs. 48.85, P = .002). Conclusions: The CDP-SOT is a reliable measure of balance and accurately differentiates disability status in people with MS. Collectively, the results support clinical application of the CDP-SOT as a reliable and valid measure of disease-related progression of impaired balance related to sensory integration and its utility in determining changes in balance in response to treatment.

Our objective was to assess the capability of computerized dynamic posturography (CDP) to evaluate dizziness in blind patients who lack corneoretinal potential. We performed a retrospective analysis of 2 young blind subjects with intraorbital scarring who complained of dizziness and underwent CDP. Tests were carried out at our center for balance disorders using the NeuroCom's EquiTest System version 4.0. CDP demonstrated vestibular dysfunction and revealed it to be severe. We conclude that CDP can serve as a potentially reliable tool for assessing dizziness in blind patients who have no corneoretinal potential.
