Summary
Benign paroxysmal positional vertigo (BPPV) often resolves after canalith repositioning maneuvers (CRM). However, some patients experience recurrence (26%) or persistence (4%) within a year, with aquatic physiotherapy aiding persistent cases.
Area of Science:
- Neurology
- Otolaryngology
- Vestibular Disorders
Background:
- Benign paroxysmal positional vertigo (BPPV) is a highly prevalent vestibular disorder.
- Effective treatments like canalith repositioning maneuvers (CRM) are crucial for managing BPPV.
Purpose of the Study:
- To investigate the one-year recurrence and persistence rates of BPPV following CRM treatment.
- To evaluate the efficacy of aquatic physiotherapy for vestibular rehabilitation (APVR) in persistent BPPV cases.
Main Methods:
- A longitudinal cohort study followed 100 BPPV patients for 12 months post-CRM.
- Patients were monitored for disease recurrence and persistence.
- APVR was implemented for individuals with persistent BPPV symptoms.
Main Results:
- Immediate CRM success was high, with 96% symptom-free.
- Over one year, 26% of patients experienced BPPV recurrence.
- A small percentage (4%) had persistent BPPV, which improved with APVR.
Conclusions:
- BPPV shows a 70% non-recurrence rate within one year post-CRM.
- Recurrence (26%) and persistence (4%) rates highlight the need for ongoing monitoring.
- APVR offers a viable treatment option for persistent BPPV.

01:15Equilibrium 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...
01:29The 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.
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
01:22Mitral 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.
01:28Dysrhythmias II: Classification of Tachyarrhythmias
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
