Aim and Scope

The Journal of Stroke (JoS) is published 3 times a year on the last day of January, May, and September. The 2015 impact factor of the JOS is 4.795. The JOS will continue to provide high quality research papers for readers and strengthen its reputation.
JOS will provide stroke clinicians and researchers with peer-reviewed articles on clinical and basic investigation of cerebral circulation and associated diseases to enhance patient management, education, clinical or experimental research, and professionalism.
The journal will consider submissions in areas including, but not limited to, the following: pathophysiology, risk factors, symptomatology, imaging, treatment, and rehabilitation of stroke. We have a particular interest in strokes in Asian populations as they have features distinct from strokes in the other part of the world. Clinical researches on intracranial atherosclerosis, small vessel diseases, or hemorrhagic strokes, and relevant basic researches are welcome, as are issues in epidemiology, public education, and clinical practice guidelines in Asian countries.
The online version is considered the canonical version of the journal because it includes all content available to the reader.
Supplementary issues are occasionally published. Some or all of the articles in this journal are indexed in Scopus, Pubmed, PubMed Central, KoreaMed, Google Scholar and DOI/Crossref.
The printed version of the journal is free if a reader is registered with the Korean Stroke Society, otherwise readers can access articles at the Journal homepage. The URL address of the journal is and The journal was supported by the Korean Federation of Science and Technology Societies Grant funded by the Korean Government (NEST).

Types of Manuscript
JOS is composed of 3 sections, in addition to articles commissioned by the Editorial Committee. All manuscripts are subject to peer review.

Original Articles. These will present original clinical and laboratory research and related topics. Although there is no set limit on the length of an original article, it is recommended that they be no longer than 5,500 words including abstract, tables, figure legends and references. An abstract no longer than 250 words should be provided with the following headings: Background and Purpose, Methods, Results, and Conclusions.
A total of 7 figures or tables are allowed; additional tables and figures may be provided using the online data supplement system.

Reviews. Abstracts are required for Reviews, but the structured abstract format of an Original Article is not necessary. Reviews have no restrictions on word count or the number of figures and tables. However, authors should eliminate redundancy, emphasize the central message, and provide only the data necessary to convey that message.
It is recommended that Reviews have the approximate length of 6,000 words including abstract, tables, figure legends, references. The total number of figures and/ or tables is limited to 7.

Letters to the Editor.
This is either a brief summary of an original research or a comment on papers previously published in this journal. We do not accept a case report unless it presents a very interesting or important finding. No abstraction is required. The letter should be 800 words or less (including references and figure legends) with a maximum of 10 references and may include only 1 figure/table. However, in case of a summary of a relatively large study, a total of 2 figures/tables are allowed; additional tables and figures may also be allowed when authors specifically request this to the editor at the time of submission.

Ethical Policy
A submitted manuscript must not be associated with any type of research misconduct. This includes fabrication, falsification, and plagiarism with intent to deceive by the authors. The corresponding author must declare in the cover letter to the Editor-in-Chief the following: the submitted manuscript has not been previously published, and the manuscript is not under simultaneous consideration for publication elsewhere, either in whole or in part in any language, except in the form of an abstract. The cover letter must also state if the manuscript contains any portion that may be regarded as redundant or duplicate information; defined as a paper, data, tables, or figures that overlap substantially with already published information. Research involving human participants must comply with the principles of the Declaration of Helsinki (1964). Articles describing 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 participants, when appropriate. The Editor-in-Chief has the right to reject a manuscript if research misconduct is suspected. Policies on the research and publication ethics not stated in these instructions can be found in "Good Publication Practice Guidelines for Medical Journals" ( or "Guidelines on good publication" (

The copyright of published manuscripts is held by the Korean Stroke Society. The authors must remember that the use of data, tables, figures, or videos (except for lectures) published in the JOS without written permission of the copyright holder is plagiarism, even if the authors use material from papers they have authored and had published in the JOS.

Online Submission Information
To submit your manuscript online, please visit the journal's online manuscript submission site (, and follow the instructions for creating an author account and submitting a manuscript. Please review the instructions on the website carefully and take note of the further instructions provided at the top of each screen of the 5 submission process stages.

Submit your manuscript and all figures exactly as instructed to avoid any failure or delay in processing.

Users must register when accessing the JOS online submission system for the first time, by clicking on "Register." You will be asked to complete 3 steps in order to obtain your personal account.

We strongly recommend using your email address as your ID, since this represents a unique and easy-to-remember identifier that will be needed each time you log onto the system (as a reviewer or author). The password will be encrypted for security reasons, and will not be known to JOS. A verification email will be emailed to you at the address you used to register.

Once you have verified your email address, you will be asked to provide a basic profile consisting of your contact information.

Uploading a Manuscript
Once logged in to the JOS online submission system, click on "Submit a new manuscript." You will be presented with a series of fields for entering information about your manuscript and uploading the manuscript, image, and supplemental files.

The system will automatically convert your files into a single PDF file for the review procedure. You will be asked to approve the conversion before your manuscript is formally submitted to the JOS. The conversion process can take up to 30 minutes, and an email will be sent informing you when the conversion is complete. Click on "Ready for you to proof" in the author area to check that the manuscript has been converted correctly.

You may begin a submission or continue the process at a later date by clicking on "Save/Continue" at the bottom of the screen when entering your manuscript information. This enables you to save that page or continue to the next page. If you choose not to complete the submission during a particular session, your manuscript will appear in the "incomplete submission" queue in "My Manuscript." Do not submit the same paper more than once.

After completing the submission, the manuscript number will be sent to the email address specified, and this should be quoted in all subsequent communications. This email notification will be sent after we have confirmed that the submitted manuscript is consistent with the journal style. Manuscripts that do not conform to the style of the JOS may be returned without further review, requiring you to correct the style of the manuscript before resubmitting it.

Supplemental Data
Supplemental Data is content that the authors wish to make available online if the paper is accepted for publication. This is currently confined to video files.

Manuscript Status
Authors who submit online using the JOS online submission system can keep track of the progress of their manuscript through the peer-review process by visiting the JOS online submission page and clicking on "My Manuscript."

Submitting a Revision
To submit a revised manuscript via the JOS online submission system, click on "Submit a revised manuscript." You will be presented with information on the original version of your manuscript, which should be edited as necessary. You will then be required to upload the files related to the revised version (see "Submitting a Manuscript" for further details). Please include your responses to the reviewer comments and a cover letter to the Editor-in-Chief. In addition, please submit a copy of the revised text with changes marked in the text using either track changes or highlighted as supplementary data.

Peer Review
Every manuscript received will be delivered to 3 peer reviewers in an anonymous fashion. If a consensus for acceptance is not reached from the initial reviewers, another reviewer will be asked to review and to determine if the manuscript is acceptable for publication. The format of the finally accepted manuscript will be edited by manuscript editors.

Manuscript Preparation
General Style
The manuscript must contain the following: author information page, title page, abstract, main text, references, tables, and figure legends. Leave margins of 2.5 cm on each side. The main body of the manuscript and all tables included with your submission must be provided in Microsoft Word format. The text must be written in double-spaced 12-point font, preferably in Times New Roman. The right margin should not be justified (i.e., left-justification only). Abbreviations should be defined on first use in both the Abstract and main text. Place the page number in the middle of the bottom of each page from the title page onwards. Do not submit the manuscript with automatic formatting features (e.g., when using EndNote, remove field codes before submission).

Cover Letter
The cover letter accompanying the manuscript must specify the type of manuscript and include statements on ethical issues and conflicts of interest, and complete contact information for the corresponding author.

The cover letter should include the following statement: "All authors have read and approved the submitted manuscript, the manuscript has not been submitted elsewhere nor published elsewhere in whole or in part, except as an abstract (if relevant)." The cover letter may include the names of up to 3 potential reviewers whom the authors would like to suggest, especially members of the editorial board. The authors may also include the names of up to 3 reviewers whom they would like not to evaluate their submission. The editor ultimately decides who will review the manuscript.

Manuscripts should be presented in the following sequence:
1. Title and author information page
2. Abstract
3. Text, including Introduction, Methods, Results, Discussion and Summary/Conclusions
4. Acknowledgments
5. Sources of Funding
6. Conflict(s) of Interest and any Disclosure(s)
7. References
8. Figure Legends
9. Tables
10. Figures

Author Information Page
Titles should be short, specific, and informative. The first page should contain all the following information: title; the full names of all authors and affiliations where the work was performed; a running title (not exceeding 50 characters, including spaces); and the contact information for the corresponding author including the complete address, telephone number, fax number, and email address. When there are multiple authors from multiple affiliations, use lower-case letters as superscripts in the order of appearance (e.g., a,b,c). Acknowledgements, sources of funding, and any conflicts of interest should be stated on this page under separate subheadings.

Sample title and author information
Low-Molecular-Weight Heparin in Atherosclerotic Stroke: A Surprising Resurrection of Anticoagulants?
Oh Young Bang,a Jong S. Kimb,c
a Department of Neurology, Samsung Medical Center, Sungkyunkwan University, Seoul, Korea
b Stroke Center and c Department of Neurology, University of Ulsan, Asan Medical Center, Seoul, Korea

Title Page
This page should contain the following: title, running title, number of characters in the title, number of words in the manuscript (excluding author information, references, tables, and figure legends), number of figures, and number of tables. The full title of the article is limited to 120 characters (including spaces). The author names should not appear on this page. This is considered the first page of the manuscript.

The Abstract must appear on a separate page. All Original Articles must include abstracts that do not exceed 250 words, and conform to the following structure: Background and Purpose, Methods, Results, and Conclusions. Each title should be terminated in boldface.

Abstracts are required for Reviews, but the structured format used in Original Articles is not necessary.

Between 3 and 6 keywords should be provided at the end of the abstract page. Important keywords can be selected from the Medical Subject Headings (MeSH) used to catalogue and index MEDLINE and Index Medicus.

Main Text
The main text of Original Article must be prepared under the following subheadings: Introduction, Methods, Results, Discussion, and Conclusions. There is no restriction on section headings for Review Articles.

The first indent should be suppressed only after a section heading and that all other paragraphs must be indented, for each paragraph, (1) ensure that it is separated from the previous paragraph by a vertical space, and (2) do not include any new-line or new-paragraph marks (except at the end of the paragraph). Do not include any new-page marks in the file.

Use SI units of measurement in all manuscripts. For example, cm should be changed to mm. The SI unit should be used in the text, followed by the conventionally used measurement in parentheses. All drugs should be referred to by their generic names rather than trade names. The generic chemical identification of all investigational drugs must be provided.

Manuscripts that describe studies on humans must indicate that the study was approved by an institutional review committee and that all participants gave informed consent. If not, the authors should state the appropriate reasons, and the Editorial Committee will decide the relevance. Manuscripts involving animals must indicate that the study was approved by an institutional animal care and use committee.

All sources of funding and financial or material support should be clearly identified in an acknowledgement. All authors are also required to report potential conflicts of interest, including funding and specific financial interests relevant to the subject of their manuscript in an acknowledgement.

References should be numbered serially in the text using numbers as unparenthesized superscripts: 1,4,7-9. They should be listed on a separate page at the end of the paper in the order first cited in the text. Unpublished data and personal communications may be cited in the text (including the initials and surnames of all authors, and the year in which the observation was made), but should not be listed as references. One copy of any in-press article that is cited in the references should be sent to the editorial office or submitted as supplementary data. Do not reference papers that are "submitted"; these can be specified as unpublished data in the body of the text. Personal communications should also be mentioned in the body of the text only.
The accuracy of reference data is the author's responsibility. Verify all entries against original sources, especially journal titles, inclusive page numbers, publication dates, accents, diacritical marks, and spelling in languages other than English. The format of references should conform with that specified in "Uniform Requirements for Manuscripts Submitted to Biomedical Journals." Journal abbreviations should conform to the style used in the Cumulated Index Medicus.
List all authors when there are 6 or fewer; when there are 7 or more, list only the first 6 and add "et al." Do not list the month/issue/day (the number in parentheses) in the reference.
