Oorzaak BPPV
Benigne Paroxysmal Positional Vertigo (BPPV) wil zeggen een goedaardige, aanvalsgewijze, positieafhankelijke draaiduizeligheid. BPPV wordt veroorzaakt door losgebroken oorsteentjes. Deze oorsteentjes van kalkzout calciumcarbonaat (statoliet) bevinden zich in het utriculum, een gedeelte van het binnenoor, en rusten hier in een gelatineuze massa op zintuigharen. Buiging van de zintuigharen informeert de hersenen over evenwicht en positie. De oorsteentjes kunnen losraken door een infectie, een hoofdtrauma of door degeneratie van het binnenoor bij het ouder worden en zich verplaatsen tot in een van de halfcirkelvormige kanalen. Normaal worden deze kanalen alleen geprikkeld door beweging van het hoofd.


Kenmerken van BPPV
Kenmerken van BPPD zijn draaiduizeligheid, aanwezig enkele seconde na het maken van een specifieke beweging van het hoofd, zoalsvoorover buigen, omrollen in bed of naar boven kijken.De duizeligheid duurt meestal niet langer dan een minuut en is vaak aanwezig in lig. Dit is een kenmerkend verschil van BPPV met andere vormen van duizeligheid

Omgaan met BPPD
Als u te maken krijgt met BPPD kunnen enkele aanpassingen in uw dagelijkse activiteiten ervoor zorgen dat de klachten zo minimaal mogelijk aanwezig zijn. Gebruik ’s nachts twee of meer kussens. Voorkom slapen op de “aangedane” zijde. Stap ’s ochtends rustig uit bed en blijf voor het uit bed stappen een minuutje op de randje van het bed zitten. Voorkom vooroverbuigen om iets op te pakken en het hoofd te ver naar achteren buigen om bijvoorbeeld naar het plafond te kijken. Wees bijvoorbeeld voorzichtig als uw haar gewassen wordt bij de kapper.

De behandeling van BPPD
De behandeling bestaat uit de A) de Modified Epley manoeuvre of B)de Modified Semont Manoeuvre gevolgd door thuisoefeningen. De Modified Epley is het meest effectief gebleken



Instructies voor patiënten na de behandeling met Epley of Semont manoeuvre :

New Vestibular Rehabilitation Techniques Can Help Patients With Dizziness

Rehabilitation is essential for patients with disabling symptoms of dizziness, vertigo, and unsteadiness caused by disorders of the vestibular system. A special issue of The Journal of Neurologic Physical Therapy (JNPT) presents an update on new and emerging vestibular rehabilitation techniques, highlighting the physical therapist's role on the multidisciplinary teams providing patient care and research. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, and pharmacy.

The special issue provides physical therapists and other professionals with an update on new developments in vestibular rehabilitation. "We hope that this Special Issue will help clinicians explore some new innovations and discoveries in physical therapist examination and treatment of persons with vestibular disorders," according to guest editors Michael C., Schubert, P.T., Ph.D., and Susan L. Whitney, P.T., Ph.D. "This issue of JNPT is unique," commented Special Issue Editor Kathleen M. Gill-Body, DPT, PT, NCS who also serves as an Associate Editor of JNPT. "Emerging data is reported for specific components of vestibular rehabilitation, and for some specialized patient populations, reflecting the more sophisticated research questions that are being asked now that the overall efficacy of vestibular rehabilitation has been established by prior studies. What was particularly exciting to me was to see preliminary data reported by several authors, and to review the authors' interpretation of the meaning and clinical relevance of their findings."

New Technologies and Emerging Techniques for Vestibular Rehabilitation

The supplement includes nine research papers and reviews, authored by an invited panel of international experts at the forefront of research and practice in vestibular rehabilitation. "The topics covered are diverse and so is the authors' expertise," Drs. Schubert and Whitney write. "The authors include physical therapists, engineers, and physicians who work to enhance the care of persons with vestibular disorders."

The original mainstay of treatment for people with vestibular disorders was developed in the 1950s and included a set of simple, progressive exercises called Cawthorne-Cooksey exercises designed to manage dizziness and improve balance following damage to the inner ear. More recently, techniques have been developed to address specific problems with gaze and postural instability, motion sensitivity, and vertigo in patients with a variety of different vestibular disorders such as benign paroxysmal positional vertigo, Meniere's disease, brain injury, and others.

Several papers report on the use of advanced technologies, such as a "balance vest" that provides patients with vibrotactile feedback to help them relearn balance function. Other topics include computerized techniques to help restore steady vision during head movements (gaze stability) and to document improvements in the ability to focus on tasks in the presence of distractions (perceptual and motor inhibition).

One study uses a device similar to a mirrored "disco ball" to provide optokinetic stimulation for patients with vestibular disorders. All of these techniques "involve some degree of innovative technology to assess treatment effectiveness, measurement of vestibular function, or reveal behavior in people with vestibular dysfunction," Drs. Schubert and Ryan write.

Physical Therapists Play Key Roles in Research and Treatment

Other articles in the special issue document the benefits of vestibular rehabilitation for specific groups of patients. One study shows that gaze stability exercises can reduce the risk of falling in older adults with vestibular disorders. Another paper is one of the first reports on the effectiveness of vestibular rehabilitation on vestibular-visual-cognitive function following blast-induced head trauma sustained by soldiers in Iraq or Afghanistan.

Similarly, a third study reports improvements in dizziness, walking and balance after participation in a customized vestibular physical therapy program in children and adults with concussion. Other articles included in the special issue evaluate the comparative benefits of different types of vestibular rehabilitation exercises (habituation exercises versus gaze stability exercises) to reduce dizziness and improve gaze stability, as well as the influence of damage to the otolith organs of the inner ear on outcomes following vestibular rehabilitation. Such studies are essential to document the effectiveness of specific rehabilitation techniques for specific groups of patients with different types of vestibular disorders.

Physical therapists play a central role in vestibular rehabilitation not only as care providers, but also in helping to advance new research in the field. The next wave of vestibular rehabilitation approaches could include virtual reality feedback and training, vestibular prostheses (implants), and even stem cell techniques, according to Drs. Schubert and Whitney. They encourage physical therapists to collaborate with researchers in evaluating these new techniques as well as in pointing out patient problems in need of new rehabilitation approaches and helping to maximize the value of new technologies.
