Pain conditions

From 2021 to 2025, 2,617 animal research papers on pain conditions mentioned at least one behavioral test, most often the von Frey test.

That is 1.1 times the 2,385 papers of 2011 to 2015. Papers that mention any of the 90 tests grew to 1.2 times as many over the same span.

The tests these papers mention

The von Frey test appears in 38% of the papers on pain conditions and in 4.0% of all 32,277 papers that mention a test. That makes it 9.5 times as common in this research. Each bar counts the papers from 2021 to 2025 on pain conditions that mention the test, with its share of the 2,617 papers. A paper that mentions two tests counts under both.

Papers on pain conditions fell from 550 in 2021 to 479 in 2023, then rose to 552 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 disease models from PubMed's indexing whenever PubMed has indexed the paper, 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 2,617 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 other species in this chart.

Which papers count

A paper counts here when it is animal research, mentions at least one of the 90 tests and studies pain conditions.

A paper counts under pain conditions when its MeSH terms, the subject headings PubMed adds when it indexes a paper, include one of these.

  • Pain
  • Chronic Pain
  • Neuralgia, with the headings under it
  • Hyperalgesia
  • Nociceptive Pain
  • Pain, Postoperative
  • Visceral Pain
  • Cancer Pain
  • Diabetic Neuropathies
  • Sciatica
  • Peripheral Nerve Injuries
  • Sciatic Neuropathy
  • Musculoskeletal Pain
  • Arthralgia

For a paper PubMed has not indexed, PubTator 3, NCBI's text-mining service, supplies the disease model when it finds the disease in the title or abstract. A paper can count under more than one disease model.

Each paper and its disease models are in the downloads. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More disease models

These disease models also have a page, with their papers from 2021 to 2025 that mention a test. Each disease model with 100 or more such papers gets one.
