Pulsed electromagnetic field (PEMF) therapy has emerged as a potential alternative. However, evidence regarding its effects on functional and psychological parameters remains scarce. Objectives: To assess the effects of 12 PEMF therapy sessions on knee extensor strength and functional performance (Timed Up and Go test\u2014TUG) in older adults with sarcopenia. Secondary outcomes included changes in calf circumference (CC), SARC-F + CC scores, and depressive symptoms. Methods: A controlled, non-randomized experimental design was employed, with a pre-intervention control group serving as a baseline reference (PEMF group: n = 25; control group: n = 16). Participants received 12 PEMF therapy sessions (three times per week) targeting the quadriceps and gastrocnemius muscles. Outcomes were measured using knee-extension dynamometry, TUG, CC, SARC-F + CC, and the Yesavage Geriatric Depression Scale. Statistical analyses included ANCOVA, with baseline values as covariates. Results: Significant improvements were observed in knee-extension strength, which increased from 13.05 \u00b1 4.8 kgf to 18.56 \u00b1 8 kgf (p &lt; 0.001); TUG test time improved from 23.1 \u00b1 14.4 to 18.7 \u00b1 10 s (p = 0.048); SARC-F + CC scores decreased from 11.6 \u00b1 8.2 to 6.5 \u00b1 7.6 (p &lt; 0.001), though the interaction effect with time was not significant (p = 0.252). No statistically significant changes were observed in CC, which increased from 34.0 \u00b1 4.0 cm to 36.0 \u00b1 3.9 cm following the intervention (p = 0.548). Yesavage Geriatric Depression Scale scores improved significantly (7.9 \u00b1 2.4 to 5.4 \u00b1 1.7, p = 0.0013). Conclusions: PEMF therapy significantly improved lower-limb muscle strength and functional mobility in elderly individuals with sarcopenia. Additionally, depressive symptoms were significantly reduced. However, no significant changes were observed in CC or SARC-F + CC.<\/jats:p>","DOI":"10.3390\/life15071111","type":"journal-article","created":{"date-parts":[[2025,7,16]],"date-time":"2025-07-16T10:46:05Z","timestamp":1752662765000},"page":"1111","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Effects of Pulsed Electromagnetic Field (PEMF) on Muscular Strength, Functional Performance and Depressive Symptoms in Elderly Adults with Sarcopenia: A Short-Term Intervention"],"prefix":"10.3390","volume":"15","author":[{"given":"Patr\u00edcia Sardinha","family":"Leonardo","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Redentor University Center\u2014AFYA, Avenida Presidente Dutra, n\u00ba 1155\u2014Cidade Nova, Itaperuna 28300-000, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9434-4231","authenticated-orcid":false,"given":"Alberto Souza","family":"S\u00e1 Filho","sequence":"additional","affiliation":[{"name":"Graduate Program, Evangelical University of Goi\u00e1s (UniEVANG\u00c9LICA), An\u00e1polis 75083-515, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9354-1460","authenticated-orcid":false,"given":"Pedro Augusto","family":"Inacio","sequence":"additional","affiliation":[{"name":"Graduate Program, Evangelical University of Goi\u00e1s (UniEVANG\u00c9LICA), An\u00e1polis 75083-515, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo Ricardo","family":"Fran\u00e7a","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Redentor University Center\u2014AFYA, Avenida Presidente Dutra, n\u00ba 1155\u2014Cidade Nova, Itaperuna 28300-000, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7285-2742","authenticated-orcid":false,"given":"Vicente","family":"Aprigliano","sequence":"additional","affiliation":[{"name":"Escuela de Ingenier\u00eda de Construcci\u00f3n y Transporte, Pontificia Universidad Cat\u00f3lica de Valpara\u00edso, Avda Brasil 2147, Valpara\u00edso 2362804, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Graduate Program, Evangelical University of Goi\u00e1s (UniEVANG\u00c9LICA), An\u00e1polis 75083-515, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel Monteiro","family":"Macedo","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Redentor University Center\u2014AFYA, Avenida Presidente Dutra, n\u00ba 1155\u2014Cidade Nova, Itaperuna 28300-000, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8395-7434","authenticated-orcid":false,"given":"Douglas Farias","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Graduate Program, Evangelical University of Goi\u00e1s (UniEVANG\u00c9LICA), An\u00e1polis 75083-515, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8548-3150","authenticated-orcid":false,"given":"Pedro Sardinha Leonardo","family":"Lopes-Martins","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Redentor University Center\u2014AFYA, Avenida Presidente Dutra, n\u00ba 1155\u2014Cidade Nova, Itaperuna 28300-000, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0911-8753","authenticated-orcid":false,"given":"Gustavo De Conti Teixeira","family":"Costa","sequence":"additional","affiliation":[{"name":"Faculdade de Educa\u00e7\u00e3o F\u00edsica e Dan\u00e7a\u2014FEFD, Universidade Federal de Goi\u00e1s (UFG\u2014Campus Samambaia), Goi\u00e2nia 74690-900, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4533-1335","authenticated-orcid":false,"given":"Rodrigo Alvaro Brand\u00e3o","family":"Lopes-Martins","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Redentor University Center\u2014AFYA, Avenida Presidente Dutra, n\u00ba 1155\u2014Cidade Nova, Itaperuna 28300-000, RJ, Brazil"},{"name":"Hospital do C\u00e2ncer de Muria\u00e9 da Funda\u00e7\u00e3o Cristiano Varella, Funda\u00e7\u00e3o Cristiano Varella, Av.
