This study aimed to assess the efficacy and cortical activity impact of a dual\u2010target electrical stimulation approach combining tDCS and TENS in the treatment of KOA after stroke. We hypothesized that the combination of tDCS with TENS could more effectively address KOA after stroke by enhancing brain activity through the induction of neural oscillations. To test this hypothesis, a double\u2010blind, randomized trial was conducted with 30 participants receiving either TENS\u2009+\u2009tDCS or TENS\u2009+\u2009sham tDCS over an 8\u2010week period, from Monday to Friday. Electroencephalograms (EEGs), Brief Pain Inventory (BPI), visual analog scale (VAS), stride length, cadence, 6\u2010min walk test (6\u2009MWT), knee range of motion (ROM), and quadriceps strength were collected pre\u2010 and poststimulation. Pain indicators were analyzed using\n                    <jats:italic>t<\/jats:italic>\n                    \u2010tests for continuous variables and chi\u2010square tests for categorical variables, with repeated measures ANOVA employed to explore changes and interactions over time. For EEG analysis, paired\n                    <jats:italic>t<\/jats:italic>\n                    \u2010tests were utilized to investigate changes in brain regions before and after treatment on the affected side, with visual analysis conducted subsequently. The results indicated that the combined treatment led to significant improvements in the affected hemisphere, with significant changes observed in \u03b11, \u03b12, and \u03b2 power. Additionally, significant group\u00d7\u2009time interaction effects were noted for BPI, VAS, stride length, cadence, and 6MWT. The study concludes that dual\u2010target electrostimulation using tDCS combined with TENS significantly ameliorates knee joint inflammation following stroke by acting on the cerebral cortex and
