چکیده
Abstract Evaluating the effectiveness of different bone conduction (BC) transducers with controlled coupling force to elicit cervical and ocular vestibular evoked myogenic potentials (cVEMPs, oVEMPs) in healthy subjects by comparing response rates, amplitudes, latencies, thresholds asymmetry ratios. Prospective experimental study including participants. VEMPs were measured stimulation modes; BC transducer was 5.4 (± 0.5) Newton. cVEMPs: conducted vibration (BCV) B81 on mastoid; oVEMPs: BCV mastoid, forehead, Mini-Shaker 4810 forehead. Air sound (ACS) insert earphones used as reference. Data 24 normal (mean age 25.3 3.0) years) analyzed. ACS B81on mastoid cVEMPs 100% ears. The highest oVEMP rates obtained (83–92%), lowest forehead (17–22%). elicited lower (65%) compared results from literature without control (78–87%). Amplitudes higher for than ACS. caused stimulation. feasible placement can be an approved medical device measure a clinical set-up. Normative values have established due variability

Cervical and ocular vestibular evoked myogenic potentials in multiple sclerosis participants
Background: Multiple sclerosis (MS) is a chronic neurological disease that affects brain and spinal cord. The infratentorial region contains the cerebellum and brainstem. Vestibular evoked myogenic potentials (VEMPs) are short-latency myogenic responses. Cervical vestibular evoked myogenic potential (cVEMP) is a manifestation of vestibulocolic reflex and ocular vestibular evoked myogenic pote...
متن کاملOcular Vestibular Evoked Myogenic Potentials
Introduction Diagnostic testing of the vestibular system is an essential component of treating patients with balance dysfunction. Until recently, testing methods primarily evaluated the integrity of the horizontal semicircular canal, which is only a portion of the vestibular system. Recent advances in technology have afforded clinicians the ability to assess otolith function through vestibular ...

Introduction: The majority of the daily life activities involve the concurrent performance of simultaneously challenging motor and cognitive activities, such as talking while walking, which requires the vestibular system for balance. Functional balance allows the brain to interpret and integrate the sensory information from our physical and social environment. This study aimed to investig...
