We noticed after publication that there are errors in Table two (table 1 of this article) of our article [1], recently published in BMC Neurology.

For answers marked in the questionnaire, the corresponding numbers are added up. Items marked with the same superscript number within one diagnosis are scored only once. E. g. the score for PPV of a patient reporting „rotational vertigo" or „perception of the environment like on a roundabout" (both marked by 1) will be diminished by 1.48 no matter whether this patient reports both or only one of these two symptoms. Patients are allowed to check only one answer per question, except for the 2nd and 3rd question.

Examples of calculated scores can be found in the Additional file 1.

Please find the corrections below:

1) A 2.82 is missing in column VM.

2) The superscripts in column BPPV are superfluous, as the last two questions allow only one answer each, as detailed in the caption.

These corrections are included in the spreadsheet files we offered upon request in the article.
