The journal of Movement Disorders adheres to the ethical guidelines for research and publication described by the Committee on Publication Ethics (COPE, http://publicationethics.org) and the ICMJE Guidelines (http:// www.icmje.org). A submitted manuscript must not be associated with any type of research misconduct, including fabrication, falsification, and plagiarism with intent the authors’ to deceive. The cover letter to the Editor-in-Chief must declare that a submitted manuscript has not been published and is not under simultaneous consideration for publication elsewhere in whole or in part in any language except in the form of an abstract. The cover letter must also state whether the manuscript contains any portion that may be considered redundant or duplicate information, defined as a paper, data, tables, or figures that overlap substantially with previously published information.
Authorship and author’s responsibility
Authorship should be limited to those who contributed significantly (or a specific role) such as the conception, design, execution, or interpretation of the submitted study. Taking primary responsibility for communication, the corresponding author should be available not only during the entire submission and review process, but also after publication to respond to any critiques or requests from the journal for data. All authors are responsible for all works of the research paper.
Any changes of authorship such as addition, deletion or rearrangement of author names should be made only before acceptance of the manuscript and only if approved by the Editorial Board. To change authorship, the corresponding author should provide i) the reason for the authorship change and ii) written confirmation (through e-mail or cover letter) from all authors that they all agree with the authorship change of addition, removal or rearrangement.
Originality and duplicate publications
Manuscripts under the process of submission/review/revision or accepted/published by other journals will not be accepted for publication. In addition, the submission of duplicate publications with similar data will not be accepted for publication without permission of the Editorial Board.
All authors should confirm that all data were the authors’ own. If any work including words of others is utilized in their manuscript, authors should cite or quote this appropriately. In addition, to avoid “self-plagiarism”, any part work of the manuscript has not been published previously, unless authors disclose a specific aim or expansion of the previous work. Transparency on the re-use should be clearly provided.
Declaration of interest
All authors should disclose any potential or financial conflict of interest to influence their work.
Human and animal rights
The author should indicate within the manuscript that the submitted study was approved by the relevant research ethics committee or Institutional Review Board (IRB). Research involving human subjects must comply with the principles of the Declaration of Helsinki (1964). Articles that describe research involving animals must state in the Methods section that the work was approved by the applicable institutional ethics committee or review board. The manuscript must also state that informed consent was obtained from the subjects, when appropriate.
When the journal faces suspected cases of research and publication misconduct–such as redundant (duplicate) publication, plagiarism, fraudulent or fabricated data, changes in authorship, an undisclosed conflict of interest, ethical problems with a submitted manuscript, a reviewer’s appropriation of an author’s idea or data, and complaints against editors–the resolution process will follow the flowchart provided by the Committee on Publication Ethics (http://publicationethics.org/resources/flowcharts). Discussion and decisions on the suspected cases are carried out by the Editorial Board.
