“…Participants performed Romberg standing balance tests without shoes, but while wearing socks to standardize footwear [30], [31], [32], on the floor and on 10.2 cm thick, medium density, Sunmate® compliant foam (Dynamic Systems, Leicester, NC), with heels and toes together and arms crossed. The four test conditions were: eyes open on the floor, eyes closed on the floor, eyes open on the foam, and eyes closed on the foam (ECF).…”

BackgroundMost HIV-seropositive subjects in western countries receive highly active antiretroviral therapy (HAART). Although many aspects of their health have been studied, little is known about their vestibular and balance function. The goals of this study were to determine the prevalences of vestibular and balance impairments among HIV-seropositive and comparable seronegative men and women and to determine if those groups differed.MethodsStandard screening tests of vestibular and balance function, including head thrusts, Dix-Hallpike maneuvers, and Romberg balance tests on compliant foam were performed during semiannual study visits of participants who were enrolled in the Baltimore and Washington, D. C. sites of the Multicenter AIDS Cohort Study and the Women's Interagency HIV Study.ResultsNo significant differences by HIV status were found on most tests, but HIV-seropositive subjects who were using HAART had a lower frequency of abnormal Dix-Hallpike nystagmus than HIV-seronegative subjects. A significant number of nonclassical Dix-Hallpike responses were found. Age was associated with Romberg scores on foam with eyes closed. Sex was not associated with any of the test scores.ConclusionThese findings suggest that HAART-treated HIV infection has no harmful association with vestibular function in community-dwelling, ambulatory men and women. The association with age was expected, but the lack of association with sex was unexpected. The presence of nonclassical Dix-Hallpike responses might be consistent with central nervous system lesions.

“…Tandem walking is widely used to screen patients for neurologic and vestibular disorders, and to screen automobile drivers for suspected intoxication. A fairly old test, it is easy to administer. Normal people can perform it well with eyes open, although performance declines with age .…”

“…TW has been used for many years to assess balance in people with vestibular disorders [6,9]; originally developed for use on narrow rails with eyes open eventually it became standardized with eyes closed [7]. Although TW is widely used, Longridge and Mallinson recently reported that less than 30% of patients or normals could perform 5 steps of tandem walking with eyes closed [15].…”

Few reliable tests are available for screening people rapidly for vestibular disorders although such tests would be useful for a variety of testing situations. Balance testing is widely performed but of unknown value for screening. The goal of this study was to determine the value of tests of walking balance for screening people with vestibular impairments. We tested three groups of patients with known vestibular impairments: benign paroxysmal positional vertigo, unilateral vestibular weakness, and post-acoustic neuroma resection. We compared them to normal subjects. All subjects were independently ambulatory without gait aids. Subjects were tested on tandem walking (TW) with eyes open and eyes closed for 10 steps, walking with no additional head motions and with augmented head rotations in yaw for 7 m (WwHT), and an obstacle avoidance task, the Functional Mobility Test (FMT). Subjects wore a 3-D motion sensor centered at mid-torso to capture kinematic measures. Patients and normals differed significantly on some behavioral measures, such as the number of steps to perform TW, and on some but not all kinematic measures. ROC analyses, however, were at best only moderate, and failed to find strong differences and cut-points that would differentiate the groups. These findings suggest that although patients and normals differ in performance of these tests in some interesting ways the groups are not sufficiently different on these tests for easy use as screening tests to differentiate the populations.
