Talk:Rhythmic movement disorder

Who or what is Zappert?
This article talks about "Zappert" identifying RMD. Clarification whether this is a person or organisation, full name, and perhaps a link to an article about this 'Zappert' would be appropriate? I'd edit this myself, but can't figure out what this refers to. 82.170.141.36 (talk) 13:28, 11 July 2015 (UTC)
