DizzyFIX
The DizzyFIX is an FDA cleared home medical device available to assist in the treatment of Benign paroxysmal positional vertigo (BPPV) and its associated vertigo. The device itself is a head-worn representation of semi-circular canals. The device is filled with fluid and a particle representing the otoconia (loose hard particles) 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.
