All participants underwent clinical assessment one week before surgery and three months postoperatively using the Harris hip score (HHS), knee society score (KSS), and oxford knee score (OKS), together with full\u2011cap EEG recordings (19 electrodes) during resting state and stair\u2011climbing motor imagery.<\/jats:p>\n                  <jats:p>\n                    EEG analysis revealed a generalized increase in low alpha band power during rest after arthroplasty in both hip (\n                    <jats:italic>n<\/jats:italic>\n                    = 33) and knee (\n                    <jats:italic>n<\/jats:italic>\n                    = 48) patients, particularly over frontocentral and parietal regions (mean increases \u223c1\u20133 \u00b5V\n                    <jats:sup>2<\/jats:sup>\n                    ;\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.001; Cohen's d up to 1.6). High alpha band changes were less consistent and often moved in the opposite direction over posterior sites, especially after knee arthroplasty and during motor imagery (\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.001).

The results support a relevant contribution of central mechanisms to postoperative outcomes and highlight qEEG as a promising tool for monitoring neuroplastic adaptation following major joint arthroplasty.This study reveals significant neuroplastic changes in cortical EEG activity post total hip\/knee arthroplasty in osteoarthritis patients, with increased low alpha and theta power over frontocentral\/parietal regions during rest and motor imagery. These alterations accompany functional improvements (HHS\/KSS), suggesting qEEG's potential for monitoring recovery.<\/jats:p>","DOI":"10.1002\/brb3.71464","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T04:35:44Z","timestamp":1777523744000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["EEG\u2010Based Cortical Alterations in Patients Following Total Hip and Knee Arthroplasty Due to Osteoarthritis: Pre\u2010 and Post\u2010Operative Assessment"],"prefix":"10.1002","volume":"16","author":[{"given":"Pawel Piotr","family":"Dobrakowski","sequence":"first","affiliation":[{"name":"Psychology Institute Humanitas Academy In Sosnowiec  Sosnowiec Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaroslaw","family":"Szyszka","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery Department Opole Rehabilitation Center  Korfant\u00f3w Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.17816\/vto101512"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.21380"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600\u20100838.2007.00702.x"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpain.2022.855493"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11517\u2010010\u20100579\u20100"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999\u2010009\u20101119\u20109"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpsycho.2003.07.001"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.26603\/001c.124840"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301\u2010620x.80b1.7859"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/1550059419879020"},{"issue":"2","key":"e_1_2_12_12_1","first-page":"155","article-title":"Kinesiophobia Negatively Influences Recovery of Joint Function Following Total Knee Arthroplasty","volume":"51","author":"Doury\u2010Panchout F.","year":"2015","journal-title":"European Journal of Physical and Rehabilitation Medicine"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2665\u20109913(23)00163\u20107"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2022.871930"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.4085\/1062\u20106050\u20100544.20"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2008.05.024"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.2015.5549"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1080\/09593985.2017.1318988"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623\u2010196951040\u201000012"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/ene.15189"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13018\u2010025\u201005936\u20104"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086\u2010198911000\u201000004"},{"key":"e_1_2_12_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2012.10.007"},{"key":"e_1_2_12_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2020.11.014"},{"key":"e_1_2_12_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2011.01.003"},{"key":"e_1_2_12_26_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891\u2010017\u20101923\u20104"},{"key":"e_1_2_12_27_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13063\u2010025\u201009053\u20109"},{"key":"e_1_2_12_28_1","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/7051079"},{"key":"e_1_2_12_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpain.2023.11.012"},{"key":"e_1_2_12_30_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0170455"},{"key":"e_1_2_12_31_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891\u2010020\u201003748\u20107"},{"key":"e_1_2_12_32_1","unstructured":"Narodowy Fundusz Zdrowia.2025.Realizacja \u015bwiadcze\u0144 endoprotezoplastyki stawowej w 2022 r.
