OBJECTIVES/HYPOTHESIS To improve the test standards for a version of the Romberg test and to determine whether measuring kinematic variables improved its utility for screening. STUDY DESIGN Healthy controls and patients with benign paroxysmal positional vertigo, postoperative acoustic neuroma resection, and chronic peripheral unilateral weakness were(More)
OBJECTIVES/HYPOTHESIS To determine whether the Sensory Organization Test (SOT) of the computerized dynamic posturography battery or the Clinical Test of Sensory Integration and Balance (CTSIB) is more likely to indicate balance disorders in people with benign paroxysmal positional vertigo (BPPV). STUDY DESIGN Normal controls were compared to patients with(More)
BACKGROUND Sleep duration is dependent on circadian rhythm that controls a variety of key cellular functions. Circadian disruption has been implicated in colorectal tumorigenesis in experimental studies. We prospectively examined the association between sleep duration and risk of colorectal cancer (CRC). METHODS In the Women's Health Initiative(More)
Locomotion is impaired in some people with vestibular disorders. Performance on cognitive tasks is also impaired in many people with vestibular disorders. The goal of this study was to determine if patients with vestibular disorders have decreased ability to complete a dual task performance involving a cognitive task, an additional motor task or both tasks,(More)
The goal of this study was to determine if parameters of gait are related to the path integration deficits in some people with vestibular disorders. We tested normals, and two groups of vestibularly impaired people, with unilateral benign paroxysmal positional vertigo and with unilateral weakness. Each group had 20 subjects. They walked straight ahead for(More)

OBJECTIVE To identify the characteristics of the gravidas delivering at our birthing center that place them at risk for false-positive human immunodeficiency virus (HIV) enzyme-linked immunosorbent assay (ELISA). STUDY DESIGN The medical records of all rapid HIV-ELISA-positive gravidas that delivered at our hospital between January 2000 and October 2001(More)
BACKGROUND Dynamic visual acuity (DVA) testing may be a useful, indirect indicator of vestibulo-ocular reflex function. Previous evidence shows that acuity for 2 m targets differs little between patients and normals using a 75 ms display duration and that healthy subjects do not differ in acuity when standing and walking while viewing a far target but they(More)
Dynamic visual acuity (DVA) may be a useful indicator of the function of the vestibulo-ocular reflex (VOR) but most DVA tests involve active head motion in the yaw plane. During gait the passive, vertical VOR may be more relevant and passive testing would be less likely to elicit compensatory strategies. The goal of this study was to determine if testing(More)
CONCLUSION The 'bucket test' may indicate that patients with known vestibular disorders have spatial orientation deficits but due to the low receiver operating characteristics (ROC) values it is not useful for screening people for vestibular impairments. OBJECTIVES 1) to verify that patients with unilateral peripheral vestibular weakness (UW) differ from(More)
BACKGROUND AND OBJECTIVES To assess self-perceived proficiency in minimally invasive surgical procedures among fourth-year Ob/Gyn residents in the United States and to evaluate trends in self-perceived proficiencies by comparing the current survey to a similar survey distributed in 2001. METHODS A Web-based survey was sent out to all fourth-year residents(More)
