Von Frey test

From 2021 to 2025, 1,282 animal research papers mentioned the von Frey test in their title or abstract, ranking it 14th of the 90 tests we track.

That is 1.6 times the 780 papers of 2011 to 2015. Papers that mention any of the 90 tests grew to 1.2 times as many over the same span.

Papers that mention the von Frey test fell from 243 in 2021 to 217 in 2023, then rose to 315 in 2025. Papers that PubMed indexed under the MeSH heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025. We take each paper's species from PubMed's indexing whenever it names one, so part of this dip may come from the indexing rather than from fewer studies.

Which species the papers used

Each bar is a share of the 1,282 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

Strains and genetic lines

Strain names come from the MeSH terms PubMed adds when it indexes a paper. PubMed has indexed 978 of the 1,282 papers, so each bar is a share of those 978.

Sprague-Dawley rats
294 papers 30%
C57BL mice
197 papers 20%
Wistar rats
120 papers 12%
Knockout mice

Transgenic mice
22 papers 2%
BALB/c mice
14 papers 1%
ICR mice
13 papers 1%
Other inbred mice
3 papers under 1%

A paper indexed under two of these headings, such as knockout mice and a strain, counts under both.

Disease models these papers study

Each bar counts the papers from 2021 to 2025 that mention the von Frey test and study that disease model, with its share of the 1,282 papers. The model comes from a paper's MeSH terms. For a paper PubMed has not indexed, it comes from PubTator 3, NCBI's text-mining service, when that service finds the disease in the title or abstract. A paper can count under more than one model.

How we counted

A count is the number of animal research papers whose title or abstract mentions one of the test's search terms. It is not a count of experiments, labs or animals.

A paper that mentions the von Frey test only in its methods is missed, so the count runs low. The count includes 7 reviews. For 305 of the 1,282 papers, PubMed's indexing gave no species, so the species came from PubTator 3 finding one in the title or abstract.

The test's search terms are in the test list download. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More pain and nociception tests

These pain and nociception tests also have a page, with their papers from 2021 to 2025. Each test with 30 or more papers gets one.
