BPPV Treatment in Biaxial Rotational Chair

2014-08-27 04:00:43 | BioPortfolio


Benign paroxysmal positional vertigo (BPPV) represents the most common cause of labyrinthine vertigo with a lifetime prevalence of 2.4 percent. Onset is most common between the fifth and seventh decades of life. The disease can be a major handicap for the affected patient, and causes a great expense for society. The traditional manual treatment with repositioning maneuvers has greatly improved the possibilities for treatment of BPPV the last decade. However some patients are still difficult to diagnose and treat, and there are some who for health reasons cannot undergo traditional manual treatment. In this perspective there is a demand for a reliable, effective and precise method to treat all semicircular canals for the differentiated patient groups, and the techniques are under continuous development.


There has been extended research to improve the techniques and develop better and more reliable methods for diagnosing and treating BPPV efficiently. An important part in this technique evolution is the development of biaxial rotational chairs that can treat the patients regardless of other health problems.

Mechanical assistance chairs have been designed to diagnose, differentiate and treat more precisely all forms of positional vertigo. The patient is strapped to a chair and fitted with infrared video goggles which identify and quantify the nystagmus in different positions. Dr. John M. Epley developed the Epley Omniax System, an automated, power driven, multi axial patient positioning device that can move the patient into any position to treat the affected canal. This chair is electronically managed. Another mechanical assistance chair, the TRV chair, developed by Thomas Richard-Vitton in Marseille France, became commercially available in 2005. This chair has a vertical and a horizontal axis of rotation and is lockable in preset positions. It is manually handled and can swivel between two axes in all planes of the semicircular canals for up to 360 degrees or more. Velocity of rotation can be regulated freely.

The TRV chair is used by 34 centers worldwide today. Bergen (Norway) was the first place in North-Europe to acquire this chair, and have used it since December 2009. In 2013 Rigshospitalet Denmark started using the TRV chair as well and Oslo University Hospital Rikshospitalet, will have their chair in 2013. The TRV chair opens for treatment that previously was not possible.

The aim of this study is to:

- Evaluate the presence of positional nystagmus in the normal population

- Evaluate the efficacy of D-BBC treatment compared to S-BBC for treatment of lateral canal BPPV in TRV chair

- Examine the serum level of vitamin D in BPPV patients

- Give a detailed description of the method.

Medical and Biotech [MESH] Definitions

Idiopathic recurrent VERTIGO associated with POSITIONAL NYSTAGMUS. It is associated with a vestibular loss without other neurological or auditory signs. Unlike in LABYRINTHITIS and VESTIBULAR NEURONITIS, inflammation in the ear is not observed.

Five-ring derivatives of dammarane having a chair-chair-chair-boat configuration. They include the lupanes, oleananes, amyrins, GLYCYRRHIZIC ACID, and soyasaponins.

A triterpene that derives from the chair-boat-chair-boat folding of 2,3-oxidosqualene. It is metabolized to CHOLESTEROL and CUCURBITACINS.

A condition characterized by the recurrence of HEMOGLOBINURIA caused by intravascular HEMOLYSIS. In cases occurring upon cold exposure (paroxysmal cold hemoglobinuria), usually after infections, there is a circulating antibody which is also a cold hemolysin. In cases occurring during or after sleep (paroxysmal nocturnal hemoglobinuria), the clonal hematopoietic stem cells exhibit a global deficiency of cell membrane proteins.

An illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. Vertigo may be associated with disorders of the inner ear (EAR, INNER); VESTIBULAR NERVE; BRAINSTEM; or CEREBRAL CORTEX. Lesions in the TEMPORAL LOBE and PARIETAL LOBE may be associated with FOCAL SEIZURES that may feature vertigo as an ictal manifestation. (From Adams et al., Principles of Neurology, 6th ed, pp300-1)
