Characteristics of BPPV.
The dizziness and nausea in this condition occurs suddenly usually due to a change in head position, commonly when rolling over or getting out of bed. The duration and intensity of the symptoms vary from person to person. Some experience them intermittently for a short time and for others it is a life long problem.
Causes of BPPV.
BPPV is the most common vestibular disorder with 2.4 % of the population experiencing it as some point in their lives. It's cause can either be due to 1) Traumatic injury 2) Infection 3) Age-related degeneration. In all three cases, the otoconia (small crystals in the membrane of the ear) become dislodged and collect in the semi-circular canals of the inner ear. Motion of the head causes these crystals to move and gives the body an aberrant sensation that leads to the dizziness and nausea.
Chiropractic treatment of BPPV.
Adjustment of the cervical spine combined with Epley's maneuver are very effective at removing the otoconia from the posterior semi-circular canal. Once the otoconia are removed it is important to remain upright for an extended amount of time to not allow them to fall back into the canal. This treatment is effective at reducing or eliminating BPPV in most cases.
