Postural instability in Meniere

Area of Science:

  • Neurology
  • Otolaryngology
  • Biomedical Engineering

Background:

  • Meniere's disease (MD) is a disorder of the inner ear affecting balance and hearing.
  • Postural instability is a common symptom in MD, but its relationship with disease duration is not fully understood.

Purpose of the Study:

  • To investigate the association between the duration of Meniere's disease and postural instability.
  • To evaluate postural sway in MD patients using posturography.

Main Methods:

  • 180 Meniere's disease patients underwent clinical examination and symptom questionnaires.
  • Postural instability was assessed using force platform posturography, measuring sway velocities (SV).
  • Patients were grouped by disease duration and hearing loss severity (pure tone average - PTA).

Main Results:

  • No statistically significant difference in mean sway velocity (SV) was found across different Meniere's disease durations.
  • A non-significant trend showed a decline in normal eyes-open SV from 73% to 38% with increasing disease duration.
  • Patients with moderate hearing loss (PTA 41-70 dB) exhibited significantly higher SV (eyes open and closed) compared to those with mild hearing loss (PTA < 25 dB).

Conclusions:

  • Disease duration does not appear to significantly impact overall sway velocity in Meniere's disease patients.
  • Hearing loss severity, specifically moderate impairment, is associated with greater postural instability in Meniere's disease.

Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.

Mitral Valve Prolapse III: Nursing Management

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
The Vestibular System01:29

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
