Prior to submission, please ensure that your manuscript is in accordance with the author guidelines below.

Articles must be submitted online via the European Journal of Pain (EJP) Editorial Manager Site - (see Section 3).

Any queries regarding the scope of the journal, the preparation of manuscripts or the submission of manuscripts may be sent to the Editorial Office at


EJP invites the following types of submission:

Original Articles
Original Articles are the journal's primary mode of communication.

Original articles must include a structured abstract including at the end a statement “Significance”, indicating the main aspects where this work adds significantly to existing knowledge in the field, and if appropriate to clinical practice. The signifiance statement should be both attention-grabbing and rigorously in line with the contents of the full article ' (see Section 4).

Review Articles
The journal aims to publish concise, topical, high-quality Review Articles of recent advances in laboratory or clinical research. Review Articles may be solicited by the Editor-in-Chief or may be submitted by authors. Any topic will be considered, but priority will be given to those addressing a major current problem and those with up-to-date literature reviews. All Review Articles are subject to peer-review.

Review articles must include a structured abstract including at the end a statement “Significance” in answer to the question 'what does this study add?' (see Section 4). Submission of a completed PRISMA checklist is required for all systematic reviews/meta-analyses.

Short Communications
Short Communications typically describe completed laboratory or clinical work. The guidelines for the preparation of Short Communications are the same as those for Original Articles, as far as applicable. The abstract is limited to 250 words and the body of the article should not exceed three printed pages. Full length articles are preferred and Short Communications will only be accepted if they are of broad interest. Generally, no pilot studies or preliminary results will be accepted.

Commentaries may provide opinion on published findings or on topics pertinent to the community of pain practitioners and researchers. Commentaries are typically commissioned by the Editors. However, suggestions for such articles are welcomed and should be directed to the Editorial Office. A commentary on a paper accepted or already published by EJP must cite the primary article.

Letters to the Editor
Letters to the Editor may be in response to issues arising from recently published articles, or as an exception, short, free-standing pieces expressing an opinion. Letters to the Editor should be formatted in one continuous section and should not exceed one printed page (800 words and 10 references). All letters are subject to peer-review.

Letters in response to a previously published article must cite the original article. At the Editors’ discretion, a letter may be sent to authors of the original paper for comment, and both letter and reply may be published together.

Randomized Controlled (Clinical) Trials

Manuscripts reporting randomised controlled trials [RCTs] must follow the CONSORT statement. RCTs will not be considered by EJP without submission of a completed CONSORT checklist. In addition, authors should consider describing the outcome measures following the IMMPACT recommendations (Dworkin et al., Pain 2005:113;9–19). For clinical trials the Clinical Study Registration Numbers has to be given. Please add this information at the end of your manuscript, before the reference list.

Qualitative Studies
While EJP has a strong focus on quantitative research, qualitative studies are also published. However, qualitative reports will only be considered for publication if they address research questions which are new or have not been extensively addressed in the empirical-quantitative literature. The findings must provide new insights..

Open Label Studies
Open label studies are occasionally considered if the topic is particularly interesting and a controlled study was impracticable.

Translations of Questionnaires
Translations of questionnaires into another language will not be considered for publication except if the study provides information and insights that go beyond the issue of translation and are of interest for international readers. Such data include for example comprehensive validity analyses including factorial validity, divergent and convergent validity or findings with regard to the clinical usefulness of a particular questionnaire.

Studies on Health Economics
Generally this journal does not publish papers on economical aspects of particular forms of pain treatments.

Case reports
Single case reports are very rarely published, series of case reports might be published if they are of broad interest.

Audits are not published in the European Journal of Pain.


All submissions should be made online at the EJP Editorial Manager site - New users will be required to register and create an account. Once a user is logged onto the site, submissions should be made via the Author Centre.


Manuscripts must be written in English.

Manuscript text must be saved in Word (.doc) or Rich Text Format (.rtf). Please do not submit text in PDF format (.pdf).

Due to space restrictions and a better readability papers generally should not exceed ten typeset pages (780 words/page, 32 references/page, including figures and tables). EJP can publish additional material as "supporting material" with a special link guiding from the manuscript to this material. Authors are encouraged to take advantage of the online-only publication option.

Suggestions for the cover inset are invited. The illustration may be from a manuscript accepted for publication in the European Journal of Pain.

Personal communications, manuscripts in preparation and other unpublished data should not be cited in the reference list but may be mentioned in the text in parentheses.

All colour illustrations will be published free of charge.

All figures must be uploaded as separate files. Figure legends should be listed on a separate page in numerical order and should contain brief but comprehensible explanations.

Figures should be referred to in the text in numerical sequence as follows: Fig. 1, Figs 2–4. The place at which a figure is to be inserted in the printed text should be indicated clearly on a manuscript. Where a figure has more than one panel, each panel should be labeled in the top left-hand corner using lower case letters in parentheses i.e. ‘(a)’, ‘(b)’ etc., and a brief description of each panel given in the figure legend.

Authors are themselves responsible for obtaining permission to reproduce previously published figures or tables. When an individual is identifiable in a photograph written consent must be obtained. This permission must include the right to publish in electronic media.

Print publication requires high quality, EPS (lineart) or TIFF/PDF (halftone/photographs) files are preferable (though GIF, JPEG, PICT or Bitmap files are acceptable for submission). MS PowerPoint and Word Graphics are unsuitable for printed pictures. Scans (TIFF only) should have a resolution of 300 dpi (halftone) or 600 to 1200 dpi (line drawings) in relation to the reproduction size (see below). EPS files should be saved with fonts embedded (and with a TIFF preview if possible).

Note to NIH Grantees
Pursuant to NIH mandate, Wiley-Blackwell will post the accepted version of contributions authored by NIH grant-holders to PubMed Central upon acceptance. This accepted version will be made publicly available 12 months after publication. For further information, see


Original Publication
Submission of a manuscript will be held to imply that it contains original unpublished work and is not being submitted for publication elsewhere at the same time. The author must supply a full statement to the Editor-in-Chief about all submissions and previous reports that might be regarded as redundant or duplicate publication of the same or very similar work.

Conflicts of Interest
Authors are responsible for disclosing all financial and personal relationships between themselves and others that might be perceived by others as biasing their work. To prevent ambiguity, authors must state explicitly whether potential conflicts do or do not exist.

When reporting experiments on human subjects, indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration of 1975, as revised in 1983. Do not use patients' names, initials or hospital numbers, especially in illustrative material. When reporting experiments on animals, indicate whether the institution's or a national research council's guide for, or any national law on, the care and use of laboratory animals was followed. A statement describing explicitly the ethical background to the studies being reported should be included in all manuscripts in the Methods section. Ethics committee or institutional review board approval should be stated.

Patients have a right to privacy that should not be infringed without informed consent. Identifying information should not be published in written descriptions, photographs and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Identifying details should be omitted if they are not essential but patient data should never be altered or falsified in an attempt to attain anonymity. Complete anonymity is difficult to achieve and informed consent should be obtained if there is any doubt. For example, masking the eye region in photographs of patients is inadequate protection of anonymity.

All persons designated as authors should qualify for authorship and all those who qualify should be listed. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. One or more authors should take responsibility for the integrity of the work as a whole, from inception to published article. Authorship credit should be based only on 1) substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it critically for important intellectual content; 3) final approval of the version to be published. Conditions 1, 2 and 3 must all be met. Acquisition of funding, the collection of data or general supervision of the research group, by themselves, do not justify authorship. All others who contributed to the work who are not authors should be named in the Acknowledgements section.

Committee on Publication Ethics (COPE)
As a member of the Committee on Publication Ethics (COPE), adherence to these submission criteria is considered essential for publication in EJP; mandatory fields are included in the online submission process to ensure this. If, at a later stage in the submission process or even after publication, a manuscript or authors are found to have disregarded these criteria, it is the duty of the Editor-in-Chief to report this to COPE. COPE may recommend that action be taken, including but not exclusive to, informing the authors' professional regulatory body and/or institution of such a dereliction.

The website for COPE may be accessed at:


Faculty of 1000
An overly extensive overlap of a submitted paper with a publication in the database of the “Faculty of 1000” might lead to rejection of the paper.

Changes of Authorship
This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts.

Before the accepted manuscript is published online: requests to add or remove an author, or to rearrange the author names, must be sent to the Editorial Manager or the Production Editor by the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Editorial Manager or the Production Editor to the corresponding author, who must follow the procedure as described above. Note that: (1) the Editorial Manager or Production Editor will inform the Editors of any such requests and (2) publication of the accepted manuscript online will be suspended until authorship has been agreed.

After the accepted manuscript is published online: any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.
