We previously found FUS parameters resulting in changes to nerve structure and reversible increased mechanical withdrawal threshold as well as reversible inhibition of motor and non\u2010pain sensory fibers. However, as behaviors were only followed for 4\u2009weeks and structure for 2\u2009weeks, the duration of increased thermal withdrawal latency and changes to nerve structure were undetermined. We investigated the duration of increased thermal withdrawal latency and nerve structure alterations after FUS application in an acute pain model. FUS was applied directly to the rat sciatic nerve prior to hindpaw (HP) incision; animal behaviors (thermal and mechanical nociceptive thresholds, HP extension and flexion) were assessed for 12\u2009weeks and nerve structure was assessed for 28\u2009weeks. The primary outcome was the change in HP thermal withdrawal latency. Secondary outcomes were the changes to sciatic nerve structure and HP mechanical withdrawal threshold, extension, and flexion. Compared with controls, after FUS application, animals had increased thermal nociceptive thresholds until week 9, increased mechanical nociceptive thresholds until week 2, decreased HP motor response until week 3.5, and decreased HP plantar sensation until week 4. Nerve ultrastructure changes may have persisted until week 24. In this new longer\u2010term follow\u2010up study, after invasive FUS application to the sciatic nerve in a rodent model of acute incisional pain, we determined the duration of changes to thermal hyperalgesia, mechanical hyperalgesia, motor, and non\u2010pain sensory responses, and changes to nerve structure.<\/jats:p>","DOI":"10.1002\/jnr.70079","type":"journal-article","created":{"date-parts":[[2025,9,24]],"date-time":"2025-09-24T10:10:46Z","timestamp":1758708646000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Focused Ultrasound\u2010Induced Peripheral Nerve Blockade: Duration of Changes to Thermal Withdrawal Latency and Nerve Structure After Focused Ultrasound Application to the Sciatic Nerve in a Rat Model of Acute Pain"],"prefix":"10.1002","volume":"103","author":[{"given":"Gwen","family":"Gao","sequence":"first","affiliation":[{"name":"Division of Behavioral and Organization Sciences Claremont McKenna College  Claremont California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4427-1416","authenticated-orcid":false,"given":"Zara","family":"Thomas","sequence":"additional","affiliation":[{"name":"Department of Chemistry Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Husniye","family":"Kantarci","sequence":"additional","affiliation":[{"name":"Department of Neuroscience University of Texas at Austin  Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cholawat","family":"Pacharinsak","sequence":"additional","affiliation":[{"name":"Department of Comparative Medicine Stanford University School of Medicine  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
