Forced swim test in pain conditions research

From 2021 to 2025, 136 animal research papers on pain conditions mentioned the forced swim test in their title or abstract.

That is 1.9 times the 70 papers of 2011 to 2015. Between the same two periods, the papers on pain conditions that mention any of the 90 tests we count grew more slowly, to 1.1 times as many.

Papers on pain conditions that mention the forced swim test fell from 33 in 2021 to 17 in 2023, then rose to 24 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. Where PubMed has indexed a paper, we take its disease models from that indexing. Otherwise PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract, or the paper is not counted here. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.

Which species the papers used

Each bar is a share of the 136 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

“Other animals” counts papers that use none of the species this chart names.

Tests mentioned alongside the forced swim test

Each bar is one test, with how many of the 136 papers also mention it, and what share that is. Of these papers, 24 (18%) mention no other test.

Which papers count

A paper counts here when it is animal research, mentions the forced swim test in its title or abstract, and studies pain conditions.

We tell whether a paper studies pain conditions from its MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. For a paper without MeSH terms, PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract. A paper can count under more than one disease model. A paper that mentions the test only in its methods is missed, so the count runs low.

The page on pain conditions research names the subject headings we count as pain conditions. Download the test list for the search terms we used for the forced swim test, or the paper list for the PubMed ID of every paper behind these counts. Our main page, Behavioral tests in published research, has the full method and each source's terms of use.

More tests and disease models

Every pairing of a disease model and a test with 30 or more papers from 2021 to 2025 has a page like this one.

The page on the forced swim test counts all the papers that mention it, whatever they study. The page on pain conditions research ranks the tests by their papers on pain conditions.
