The DizzyFIX device and hat

The DizzyFIX is a home medical device available to assist in the treatment of Benign Paroxysmal Positional Vertigo (BPPV) and its associated vertigo. [1] The device itself is a head-worn representation of semi-circular canals. The device is filled with fluid and a particle representing the otoconia associated with BPPV. The device works like a visual set of instructions and guides the user through the treatment maneuver for BPPV. This maneuver is called the particle repositioning maneuver or Epley maneuver.

BPPV

Nystagmus.

BPPV is the most common cause of peripheral vertigo.[2] It can be characterized by three main symptoms: positional onset, spinning dizziness and short lived symptoms. The primary diagnostic maneuver is the Dix-Hallpike which elicits the cardinal sign associated with BPPV, rotatory nystagmus.

Background

The DizzyFIX was originally developed by Ear Nose and Throat (ENT) physicians to assist in the long term treatment of patients with a known history of recurrent BPPV[3]. BPPV is frequently highly recurrent with rates as high as 50%[4]. Radtke et al have suggested that home treatment is both safe and effective when training is adequate but that the key cause of failure of the home treatment is an imperfect repositioning maneuver[5]. As a result of failed home treatments the DizzyFIX was developed to assist patients in the performance of a correct particle repositioning maneuver. Research to date indicates that use of the device is correlated with a correct particle repositioning maneuver (Beyea, 2007).

The device was subsequently manufactured by Clearwater Clinical Limited of Calgary, Alberta and further research was undertaken at the University of Western Ontario, London, Ontario.

Research

Beyea et al used the DizzyFIX as an objective measure of a various methods of medical education. DizzyFIX outcome was compared with objective observers of participants performance.

Further research dealing with the design and clinical application of the device is in press in the Journal of Otolaryngology - March 2008.

Device Certification

  • The DizzyFIX is CE registered in the European Union.
  • The DizzyFIX device is a Class I medical device according to Rule 7( 1) of the Medical Devices Regulations and has been reviewed and determined to be such by the Device Licensing section of the Medical Devices Bureau of Health Canada.
  • The DizzyFIX complies with Canada's Medical Devices Regulations, which include:Safety and effectiveness (Sections 10 to 20,21 to 23,52 to 58, 59 to 62 and 63 to 65). It also complies with the requirements of Sections 3 and 19 to 21 of Canada's Food and Drugs Act.
