Interrater and Intrarater Agreement in Neonatal Electroencephalogram Background Scoring.

Many neonates undergo electroencephalogram (EEG) monitoring to identify and manage acute symptomatic seizures. Information about brain function contained in the EEG background data may also help predict neurobehavioral outcomes. For EEG background features to be useful as prognostic indicators, the interpretation of these features must be standardized across electroencephalographers. We aimed at determining the interrater and intrarater agreement among electroencephalographers interpreting neonatal EEG back...

Validation of three-dimensional wound measurements using a novel 3D-WAM camera.

In order to monitor wound healing it is essential to obtain accurate and reliable wound measurements. Various methods have been used to measure wound size including three-dimensional (3D) measurement devices enabling wound assessment from a volume perspective. However, the currently available methods are inaccurate, costly or complicated to use. As a consequence, we have developed a 3D-WAM camera (Wound Assessment Monitor camera), which is able to measure wound size in three-dimension and to assess wound ch...

Is There a Safe Level for Recording Vestibular Evoked Myogenic Potential? Evidence From Cochlear and Hearing Function Tests.

There is a growing concern among the scientific community about the possible detrimental effects of signal levels used for eliciting vestibular evoked myogenic potentials (VEMPs) on hearing. A few recent studies showed temporary reduction in amplitude of otoacoustic emissions (OAE) after VEMP administration. Nonetheless, these studies used higher stimulus levels (133 and 130 dB peak equivalent sound pressure level [pe SPL]) than the ones often used (120 to 125 dB pe SPL) for clinical recording of VEMP. Ther...

The role of vestibular evoked myogenic potentials in multiple sclerosis-related vertigo. A systematic review of the literature.

Vertigo is a common symptom of multiple sclerosis (MS) that can be caused by a central or peripheral involvement of the vestibular pathways. Magnetic Resonance Imaging (MRI) is commonly used to evaluate progression of MS but is not sensitive enough to detect small lesions. Vestibular evoked myogenic potentials (VEMPs) are commonly used to evaluate function of vestibular-cochlear pathways. The aim of this literature review is to evaluate the role of VEMPs in patients with MS-related vertigo as a tool to dete...

Simultaneous four-channel recording of bilateral cervical and ocular vestibular-evoked myogenic potentials in response to stimulation by forehead bone-conducted vibration: Our experience in 20 healthy adults.

Various vestibular stimuli, including air-conducted sound (ACS), bone-conducted vibration (BCV), and galvanic vestibular stimulation (GVS), can be used to elicit vestibular-evoked myogenic potential (VEMP). VEMP obtained from the sternocleidomastoid (SCM) muscle is called cervical VEMP (cVEMP), while that recorded at extraocular muscles is termed ocular VEMP (oVEMP). cVEMP was first recognized as fundamental in determining the sacculo-collic reflex (SCR) pathway in the mid-1990s. In the mid-2000s, oVEMP was...

Computerized Dynamic Posturography does not detect measured CVEMP and OVEMP abnormalities.

Computerized Dynamic Posturography (CDP)was developed by the American space program to assess imbalance in astronauts, and eventually evolved into a clinical diagnostic tool. However it is not a specific measure of vestibular function. Vestibular Evoked Myogenic Potential testing (VEMPs) is a new clinical tool which is sensitive and specific for measuring otolithic pathology, especially in the atypical vestibular patient.
