Table of Contents

Journal of Electrodiagnosis and Neuromuscular Diseases (J Electrodiagn Neuromuscul Dis, JEND), an official journal of the Korean Association of EMG Electrodiagnostic Medicine, is published three times a year. It regards all aspects of EMG, electrodiagnostic medicine, and neuromuscular diseases, including clinical practice, experimental and applied research, and education, and its formal abbreviated journal name is J Electrodiagn Neuromuscul Dis.

The manuscript guidelines for JEND are based on the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals” (http://www.icmje.org/recommendations/), and instructions which are not mentioned in the present guidelines are referred to the guidelines stated in the Recommendations.

Editorial Board will make the final decision on approval for the publication of submitted manuscripts and the publication order of accepted manuscripts. Editorial Board reviews ethics, rationality, originality, and scientific significance in accepting submitted manuscripts, and can request any further corrections, revisions, and deletions of the article if necessary.


1-1. Qualifications for authorship

Authors should be limited to members of Korean Association of EMG Electrodiagnostic Medicine, associate members of Korean Association of EMG Electrodiagnostic Medicine or those who are associated with clinical practice, experimental and applied research, and education in the field of EMG, electrodiagnostic medicine, and neuromuscular diseases.

Authorship is credited to those who have direct involvement in the study and have made significant contributions to (a) conceptualization and design of the research, or acquisition, analysis, and interpretation of the data, (b) drafting of the manuscript or critical revision, and (c) approval of the submitted and final versions of the manuscript. The primary investigator is designated the first author of the study unless contested by the other authors. The corresponding author is directly responsible for communication and revision of the submitted manuscript.

In the case that more than one author contributed equally as the first author or the corresponding author, the acceptance of cofirst or co-corresponding author should be determined through discussion of the Editorial Board. Everyone who is listed as coauthors should have made a substantial, direct, intellectual contribution to the work.

In the case of a change of authorship, a written explanation must be submitted. Change in either the first author or the corresponding author requires approval by the Editorial Board, and any changes of other authors require approval by the Editorin-Chief.

1-2. Types of manuscript

Manuscripts include Original Articles, Case Reports, Brief communications, and Reviews, commissioned by the Editorial Committee on EMG, electrodiagnostic medicine, and neuromuscular diseases.

1-3. Duplicate or secondary publication

All submitted manuscripts should be original and should not be considered by other scientific journals for publication at the same time. No part of the accepted manuscript, including the table and the figure, should be duplicated in any other scientific journal without the permission of the Editorial Board. If duplicate publication related to the papers of this journal is detected, the manuscripts may be rejected.

But, if the authors have received approval from the editors of both journals (the editor concerned with secondary publication must have access to the primary version), secondary publication may be allowed only under the conditions for secondary publication stipulated in the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals.” The secondary version informs that the paper has been published in whole or in part elsewhere, and the secondary version cites the primary reference.

If the unauthorized duplicate publication is discovered, authors will be announced in the journal, and their institutes will be informed and are subject to penalties and/or unfavorable outcomes including prompt rejection or prohibited submission.

1-4. Ethical considerations

For all studies involving human subjects, the principles embodied in the Declaration of Helsinki 2013; https://www.wma.net/policies-post/wma-declaration-of-helsinki-ethical-principles-for-medical-research-involving-human-subjects/) should be upheld, informed consent must be obtained from all participants, and must be approved by a recognized Institutional Review Board (IRB) or research ethics committee.

Any information that could have revealed subjects’ identities, such as name and initials, should not appear in the text. If a photo is presented, proper measures should be taken not to reveal the subject’s identity, or written consent must be presented for the photo and possible disclosure of the subject’s identity.

Experiments involving animals should comply with the NIH guidelines for the use of laboratory animals and/or be reviewed by an appropriate committee (Institutional Animal Care and Use Committee, IACUC) to ensure the ethical treatment of animals in research.
