Methods: This exploratory, nonrandomized, open-label study enrolled 20 adults aged 60\u201390 years, allocated by order of entry to consecutive, nonconcurrent cohorts of auricular laser acupuncture (n\u2009=\u200910) or seed acupressure (n\u2009=\u200910), treated twice weekly for five weeks. VAS, McGill, SF-36, and thermography were assessed before the first (A1) and fifth sessions (A2) and after the tenth (A3) and analyzed using linear mixed-effects models. Results: From A1 to A3, VAS decreased by \u2212\u20092.70 points in Laser (95% CI\u2009\u2212\u20094.37 to \u2212\u20091.03) and \u2212\u20092.50 in Seed (95% CI\u2009\u2212\u20094.17 to \u2212\u20090.83); the between-group difference was \u2212\u20090.20 points (Laser\u2009\u2212\u2009Seed; 95% CI\u2009\u2212\u20092.54 to 2.14). Selected McGill and SF-36 outcomes changed; McGill affective A1-to-A2 change differed between groups (Laser\u2009\u2212\u2009Seed: \u22122.70; 95% CI\u2009\u2212\u20094.86 to \u2212\u20090.55; p\u2009=\u20090.017). Anterior thermal range (\u0394T) showed a TIME \u00d7 GROUP interaction (p\u2009=\u20090.007); the A1-to-A3 between-group difference was \u2212\u20091.941 \u00b0C (Seed\u2009\u2212\u2009Laser; 95% CI\u2009\u2212\u20093.097 to \u2212\u20090.785), although Seed \u0394T was higher at baseline (+\u20091.496 \u00b0C; 95% CI 0.607 to 2.385). Lateral \u0394T showed a TIME effect (p\u2009=\u20090.033); posterior \u0394T showed none. Conclusion: Clinical outcomes improved over time without evidence of differential changes between interventions. Thermography identified region-specific \u0394T trajectories, warranting further investigation as a complementary method.<\/jats:p>\n                  <jats:p>Clinical trial registration: ClinicalTrials.gov NCT07010627.<\/jats:p>","DOI":"10.1007\/s10103-026-05078-x","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T10:06:31Z","timestamp":1792577191000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Thermographic outcomes of auricular laser acupuncture and auricular seed acupressure in older adults with chronic shoulder pain: an exploratory nonrandomized, nonconcurrent comparison"],"prefix":"10.1007","volume":"41","author":[{"suffix":"Jr","given":"Gerson","family":"Quadros","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3526-3890","authenticated-orcid":false,"given":"Emilia Angela","family":"Lo Schiavo Arisawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9360-7407","authenticated-orcid":false,"given":"Lu\u00eds Eduardo","family":"Soares","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,10,21]]},"reference":[{"issue":"1","key":"5078_CR1","doi-asserted-by":"publisher","first-page":"51","DOI":"10.4314\/ejhs.v35i1.8","volume":"35","author":"A Hajizadeh","year":"2025","unstructured":"Hajizadeh A, Hafezi R, Torabi F, Sari AA, Tajvar M (2025) Consequences of population aging on health systems: a conceptual framework for policy and practice.
