Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This manuscript examines the application of electrical stimulation (ES) as a supplementary treatment for acute burns, addressing a notable gap in systematic evidence within this domain and presenting an innovative approach.

  1. Introduction

1)The introduction lacks a comprehensive discussion on the "differences in electrophysiological mechanisms between acute burns and chronic wounds,". It is advisable to incorporate relevant literature to substantiate this point.

 

2)Expand the conversation about the state of acute burn care today (such as the shortcomings of current treatments) and emphasize the necessity of ES.

  1. Discussion and conclusions

1)It explains why certain investigations have revealed notable effects when combined with the molecular processes by which ES stimulates cell migration (e.g., fibroblasts, keratinocytes) (e.g., calcium signaling pathways, growth factor release).

 

2) Mechanistic explanation: A more thorough examination of how ES reduces bacterial load is warranted. Furthermore, the distinct impacts of various current types (DC versus AC) on the healing phases.

It is advisable to accept it following the incorporation of the aforementioned details.

good study, but why did he do it for adults only, why not for pediatrics?

Author Response

Comments 1: good study, but why did he do it for adults only, why not for pediatrics?

Response 1: Thank you for the positive review comment. In relation to the challenges of application of ES in children, the scope of this review was kept to adults. That said, the reviewer makes a good pitch for a future review.

Reviewer 3 Report

Comments and Suggestions for Authors

Overall: Interesting article, well written and structured. Small corrections have to be done. 

  1. Title: It's confusing, I suggest something more appealing like: "Enhancing Burn Recovery: A Systematic Review on the Benefits of Electrical Stimulation in Accelerating Healing"
  2. English grammar, sentence structure, and article design: Well written and structured article. All the ideas are put across in a clear and interconnected way.
  3. Abstract: The abstract is good and has everything that is needed. Everything is connected and well-written. However, the keywords can't be the same as the ones in the title, please review that. Furthermore, the graphic that comes after, I like to point out that it´s an amazing graphic, however I´m confused: Is this the abstract graphic or a figure for the text? Because if it is the second, this should have a legend and be cited on the text, and only after the introduction
  4. Introduction: Again, the introduction is good and has everything that is needed. Nothing to point out.
  5. Methods: Once again, the Methods are good and have everything that is needed. However, I suggest an alteration, in line 130-131: “Further terms and search strategy are documented in Appendix A. The results of acute burn searches 130 and electrical stimulation searches were combined using the Boolean operator AND.”
  6. Results: This section is good and has everything that is needed. But I have to point out the unreadable tables 1,2, and 3 – I suggest simplifying and shortening the text in the table and putting it bigger.
  7. Discussion: Again, this part is good and has everything that is needed. However, I suggest a rewriting of this part in a way to use the connected terms throughout the text, like: Furthermore, Additionally, On the contrary, etc - only to connect more the text.
  8. Conclusion: Again, this section is good and has everything that is needed. I have nothing to point out.
  9. References: I have nothing to point out.

Response 8: Thank you. We will work with the publisher to improve the visibility of the tables as they are submitted as figures to adhere with formatting requirements.

Comments 9: Discussion: Again, this part is good and has everything that is needed. However, I suggest a rewriting of this part in a way to use the connected terms throughout the text, like: Furthermore, Additionally, On the contrary, etc - only to connect more the text.

Response 10: Thank you for the positive comments.

Reviewer 4 Report

Comments and Suggestions for Authors

Overall a very well presented review. It clearly follows the appropriate reporting guidelines. The topic is of clinical interest and it was an enjoyable read.

Suggestions:

The abstract could be a little clearer about the primary outcome of the study - this is made very clear in the introduction (see below) so consider adding specific outcomes measured.

One small typographical error shown in red (This needs to be replaced with The)

The primary aim of this review was to evaluate the effectiveness of ES as an adjunct to routine wound care for accelerating acute burn wound healing, when compared to routine wound care alone. The primary outcome investigated was time to re-epithelization, with secondary outcomes including edema management and reduction of pain and infection.

The Figure on Page 2 is somewhat unconventional - it appears to be a poster style Figure to summarise the results. This may be better at the end of the manuscript (depending on the Editors views).

Reviewer 5 Report

Comments and Suggestions for Authors

Dear authors,

Thank you very much for considering EBJ for publication of your revised »Electrical stimulation is beneficial as an adjunct to routine care, reducing healing time of acute burns in adult patients: A systematic review«.

Overall, this systematic review provides valuable insights into the potential benefits of ES in acute burn wound healing. Addressing the methodological and interpretive concerns outlined would improve the clarity, reliability and applicability of the findings. You have also nicely demonstrated the purpose of the study and its findings with interesting diagrams.

You might also consider discussing the clinical significance of the digital photography, transepidermal water loss, and bioimpedance spectroscopy metrics (e.g., their reliability, validity, and correlation with functional outcomes), as this might strengthen the practical applicability of your findings.

We have no further comments.

I have carefully reviewed the manuscript. The introduction reflects the research direction, the methodology is properly and reliably conducted, and the results are consistent and clear. However, in the recommendations, it is suggested that reviews should be registered in the PROSPERO database, which can also be done after the study is completed. Despite my positive review, the final decision on accepting the paper is left to the editor-in-chief. I have no further comments on the work. Congratulations and best regards.

Response 1: Thank you to Reviewer 6 for their positive comments. Unfortunately, PROSPERO will not accept submissions of review protocols in retrospect. We will certainly submit our protocol a priori in future. Thank you for the comment.
