Research summary
Benign Proximal Positional Vertigo (BPPV) is a common balance disorder that affects around 2.4% % of the entire UK population, (Brevern et al 2007). The condition is more likely to occur with age with most cases classified as idiopathic, (Katsarkas et al, 1999). BPPV is easily diagnosed and usually treatable using particle repositioning manoeuvres (Steenerson et al 2005). The condition has a high incidence of reoccurrence with up to 41% of people diagnosed and treated for BPPV suffering a repeat attack within two years (Helminski et al 2005). There are currently over thirty three thousand references on Google that suggest levels of dietary salt and caffeine cause BPPV.
This exploratory pilot study proposes to examine if there are differences in the dietary levels of patients with BPPV and those patients with normal vestibular function. The research will be in the form of a comparison of the dietary intake between BPPV sufferers and people reporting with no vestibular problems.
The study will be in the form of a three day food and drink questionnaire-based comparison of BPPV sufferers and people reporting with no balance problems. The study will consist of two groups of ten patients, one comprising of BPPV sufferers and one comparison group of non-sufferers. The non BPPV group will only be asked to provide one diet diary which can be used as normative data.REC name
