Physioter"],"abstract":"<jats:p>Introduction:\u00a0The presence of altered central pain processing and modulation, as well as negative psychological factors, have been suggested to impede recovery in chronic low back pain (CLBP). Psychologically-informed physiotherapy (PiP) aims to specifically address the latter factors\u2014in addition to physical factors\u2014to improve treatment effects. This study aims to determine if the effect of PiP is superior to usual physiotherapy (UP) on pain sensitivity and modulation in participants with CLBP and if changes in these variables were associated with changes in clinical outcomes.\nMethods:\u00a0Forty participants with CLBP were randomly allocated to PiP or UP. Seven physiotherapy sessions over 6 weeks plus a booster session at an 11-week follow-up were delivered. Pressure pain threshold (PPT), temporal summation of pain (TSP), and exercise-induced hypoalgesia were assessed on lumbar, upper, and lower limb sites at baseline and after 6 weeks. Linear mixed models tested if PiP was superior to UP on pain sensitivity\/modulation. Linear regressions tested if pain sensitivity\/modulation changes were associated with changes in clinical outcomes (pain intensity, physical functioning, symptoms of central sensitization).\nResults:\u00a0PiP was not superior to UP to modulate pain sensitivity\/modulation variables. All PPTs increased after 6 weeks regardless of the approach. Lumbar PPT and lumbar and lower limb TSP changes were associated with physical functioning changes.\nConclusion:\u00a0Although our study suggests that neither approach has a superiority to impact on pain sensitivity, both approaches elicited widespread hypoalgesia. Future powered trials should verify if pain sensitivity can be a mediator of physical functioning improvement, as suggested by our results.<\/jats:p>","DOI":"10.33393\/aop.2025.3323","type":"journal-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T14:42:42Z","timestamp":1739803362000},"page":"32-41","source":"Crossref","is-referenced-by-count":2,"title":["Comparisons of the effects of psychologically-informed and usual physiotherapy on pain sensitivity in chronic low back pain: an exploratory randomized controlled trial"],"prefix":"10.33393","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4472-9656","authenticated-orcid":false,"given":"Hugo","family":"Mass\u00e9-Alarie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6291-4866","authenticated-orcid":false,"given":"Am\u00e9lie","family":"Desgagn\u00e9s","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1800-1832","authenticated-orcid":false,"given":"Claudia","family":"C\u00f4t\u00e9-Picard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4326-4165","authenticated-orcid":false,"given":"Olivier","family":"Liberty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4339-3687","authenticated-orcid":false,"given":"Pierre","family":"Langevin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4171-2226","authenticated-orcid":false,"given":"Mathieu","family":"Pich\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1133-8707","authenticated-orcid":false,"given":"Yannick","family":"Tousignant-Laflamme","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"18642","published-online":{"date-parts":[[2025,2,17]]},"reference":[{"key":"15180","doi-asserted-by":"crossref","unstructured":"Meucci RD, Fassa AG, Faria NM.
