CCBS Subcommittees

The following guidelines were agreed to during the Bárány Society business meeting on May 27th, 2014 in Buenos Aires.

Composition of the Subcommittees

Every subcommittee will have a chair designated by the Classification Committee of the Bárány Society (CCBS). The chair of a subcommittee should be a member of the Bárány Society and report to the CCBS. He/she will compose his/her own subcommittee group according to the following guidelines:

• Minimum 3 continents represented
• Minimum of one clinician with ENT background
• Minimum one clinician with neurology background
• Additional expertise from different backgrounds (like vestibular testing or imaging, etc.) should be sought out as needed
• Input from each member of a working group should be such that it will qualify for authorship (this should encourage small efficient working groups)

Procedures

No more than 12 months should elapse from the designation of the coordinator to presentation of first proposal to the CCBS. Each paper will undergo an internal review and consensus process for ICVD Publications in the Journal of Vestibular Research (JVR).

1. Subcommittee completes draft document and together with the CCBS, decides it is ready for input from the Bárány Society membership.
2. The draft document is placed on the JVR website and Bárány Society members are alerted via email or other electronic means that a draft document is ready for comments. Only Bárány Society members are able to access this page.
3. Comments are provided by interested Bárány Society members via the JVR website. NOTE: These comments are only visible to the Editor of JVR and not available to the public.
4. The Editor of JVR forwards all legitimate comments to the relevant subcommittee chair.
5. At their own discretion, the subcommittee chairs respond to individual comments by replying to the member who provided the comment, revising the draft document, or both. The subcommittee chair can also decline to respond. The subcommittee chair will involve subcommittee members as they see fit.
6. After approximately 3 months, a revised document that incorporates comments received from the Bárány Society membership is prepared by the subcommittee.
7. The subcommittee chair, with the agreement of the subcommittee members and the CCBS, decides whether or not the document is ready for input from colleagues outside the Bárány Society. If additional input is necessary from the Bárány Society membership based on the extent of the revisions, a revised document is placed on the JVR website and another round of comments is accepted. If the subcommittee chair and members determine that the document is ready for outside comments, the subcommittee seeks input from relevant societies.
8. After revisions based on comments received from relevant outside societies, a penultimate draft is placed on the JVR website for comment from the Bárány Society membership.
9. As above, relevant comments from Bárány Society members are forwarded to the subcommittee chair by the Editor of JVR and appropriate revisions are made.
10. The subcommittee, after getting approval from the subcommittee chair, subcommittee members, and the CCBS, advises the Editor of JVR that the document is ready for publication.
11. JVR publishes the document as a special publication available in print and online as an open access article on both the IOS website and the JVR‐web.org website.

Publication and Authorship

The work of the various subcommittees will be submitted for publication to JVR after the final approval by the CCBS. The members of the subcommittee will be listed as the authors, with the chair as the first author and will include the addendum “on behalf of the CCBS.” This is according to the model of the Symptom classification paper.

Dissolution of a Subcommittee

After publication of its definition, the subcommittee is dissolved. The revision and possible updating of the definition will be done according to the same procedure as described above. All members of the previous subcommittee are eligible for the revision subcommittee.

Format and Content of the Definitions

To establish the definitions all available types of evidence should be taken into account: clinical description, pathophysiology, vestibular tests, imaging, treatment results, genetics, epidemiology, etc. and should retain what is essential for the disease definition.

Currently, the following vestibular disorders and topics are addressed in subcommittees:

• Vestibular syndromes nomenclature classifications (David Newman Toker)
• Nystagmus classification (Scott Eggers)
• Functional and psychiatric aspects (Jeff Staab)
• Vestibular migraine (Thomas Lempert)
• Meniere’s Disease (Antonio López Escámez)
• BPPV (Michael von Brevern)
• Vascular vertigo (Michael Strupp)
• Acute unilateral vestibulopathy (Måns Magnusson)
• Presby-vestibulopathy (Yuri Agrawal)
• Cervical vertigo (Barry Seemungal)
• Bilateral vestibulopathy (Michael Strupp)
• Motion sickness and mal de debarquement (Yoon-Hee Cha)
• Measuring functioning, participation, and quality of Life (Joe Furman, Eva Grill)
• Laboratory testing (Herman Kingma)
• Postconcussion vestibular disorders (Michael Hoffer)
• Superior canal dehiscence (John Carey)

A series of consensus documents is finished or currently under development by the Committee for the Classification of Vestibular Disorders (ICVD) of the Bárány Society. To see a list of these documents, please click here.

As mentioned above, all finalized documents of the CCBS are published open access in the Journal of Vestibular Research.
