Previous studies have shown that dual-task costs in gait are associated with future falls and cognitive decline. According to the communication through coherence hypothesis, transcranial alternating current stimulation (tACS) might help alleviate this problem. Objective: The aim of this study was to examine the effects of a single session of theta-tACS targeting the left fronto-parietal network (L-FPN) on dual-task walking and cognitive function compared to sham stimulation and transcranial direct current stimulation (tDCS) targeting the left dorsolateral prefrontal cortex, a node within the L-FPN. Methods: Twenty older adults completed a four-visit, double-blinded, within-subject, cross-over study in which usual-walking, dual-task walking, and cognitive function were evaluated before and immediately after 20 min of tACS, tDCS, or sham (order randomized) stimulation. Dual-task costs to gait speed (primary outcome) and other measures were analyzed. Results: The dual-task cost to gait speed tended to be lower (i.e., better) after tACS (p = 0.067, Cohen\u2019s d = 0.433\u223csmall); tDCS significantly reduced this dual-task cost (p = 0.012, Cohen\u2019s d = 0.618\u223cmedium), and sham stimulation had no effect (p = 0.467). tACS significantly reduced the dual-task cost to step length (p = 0.037, Cohen\u2019s d = 0.502\u223cmedium); a trend was seen after tDCS (p = 0.069, Cohen\u2019s d = 0.443\u223csmall). No statistical differences were found for other measures of gait or cognitive function. Conclusions: The positive effects of tACS on dual-task gait speed and step length were roughly similar to those seen with tDCS. These results suggest that tACS affects the fronto-parietal network and, similar to tDCS, tACS may improve dual-tasking. Nonetheless, to achieve larger benefits and differentiate the effects of tACS and tDCS on brain function and dual-task walking in older adults, other stimulation montages and protocols should be tested. <\/jats:p>","DOI":"10.1159\/000527171","type":"journal-article","created":{"date-parts":[[2022,12,5]],"date-time":"2022-12-05T22:00:57Z","timestamp":1670277657000},"page":"513-518","source":"Crossref","is-referenced-by-count":6,"title":["The Potential of Transcranial Alternating Current Stimulation to Alleviate Dual-Task Gait Costs in Older Adults: Insights from a Double-Blinded Pilot Study"],"prefix":"10.1159","volume":"69","author":[{"given":"Rony M.","family":"Sayig-Keren","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moria","family":"Dagan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"Cornejo Thumm","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Brozgol","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eran","family":"Gazit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0776-237X","authenticated-orcid":false,"given":"Brad","family":"Manor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey M.","family":"Hausdorff","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2022,12,5]]},"container-title":["Gerontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/ger\/article-pdf\/69\/4\/513\/3954713\/000527171.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/ger\/article-pdf\/69\/4\/513\/3954713\/000527171.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:23:39Z","timestamp":1745421819000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000527171"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,12,5]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2023,4,3]]},"published-print":{"date-parts":[[2023,4,20]]}},"URL":"https:\/\/doi.org\/10.1159\/000527171","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.21673412","asserted-by":"subject"}]},"ISSN":["0304-324X","1423-0003"],"issn-type":[{"value":"0304-324X","type":"print"},{"value":"1423-0003","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,12,5]]}}}
