This randomized clinical trial included 104 postpartum women recruited between April and October 2024, who were allocated into two groups: a control group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200952) and an experimental group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200952). The experimental group received infrared LLLT at a dose of 5\u00a0J\/cm\u00b2. Pain intensity was assessed using the Visual Analog Scale (VAS), and wound healing was evaluated using the Vancouver Scar Scale (VSS). Two LLLT sessions were performed at 12\u201324\u00a0h and 48\u00a0h postpartum. A significant reduction in pain intensity was observed after the second application (mean difference [MD]: \u22121.4; 95% CI: \u22122.3 to \u2212\u20090.5), as well as an improvement in overall wound healing quality (MD: 3.31; 95% CI: 3.19 to 3.43). Domain-specific analysis of the VSS revealed improvements in vascularity (MD: 1.0; 95% CI: 1.00 to 1.03) and scar pliability (MD: 1.11; 95% CI: 1.07 to 1.15). No significant differences were observed in global health perception or in the need for pharmacological analgesia. These findings suggest that LLLT is effective in reducing postoperative pain intensity and improving wound healing quality\u2014particularly in terms of scar vascularity and pliability\u2014in women undergoing cesarean section.\n                  <\/jats:p>\n                  <jats:p>Clinical trial registration<\/jats:p>\n                  <jats:p>This study was prospectively registered in the Brazilian Registry of Clinical Trials (ReBEC) under the registration number RBR-4pkhf4b.<\/jats:p>","DOI":"10.1007\/s10103-026-04934-0","type":"journal-article","created":{"date-parts":[[2026,6,25]],"date-time":"2026-06-25T02:15:53Z","timestamp":1782353753000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effectiveness of low-level laser therapy compared to standard postoperative care on pain intensity and cesarean section wound healing in the immediate postoperative period: a randomized clinical trial"],"prefix":"10.1007","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9458-1455","authenticated-orcid":false,"given":"Maria Luci","family":"Quirino de Melo Trindade","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre","family":"Delgado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuri","family":"Miranda de Alencar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasmin","family":"Eduarda da Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Eduarda","family":"da Concei\u00e7\u00e3o Silveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Lemos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,25]]},"reference":[{"issue":"11","key":"4934_CR1","doi-asserted-by":"publisher","first-page":"1045","DOI":"10.1590\/1806-9282.64.11.1045","volume":"64","author":"C Dalmoro","year":"2018","unstructured":"Dalmoro C, Rosa R, Bordin R (2018) Normal delivery and cesarean section: cost per Brazilian regions, 2015.
