We aimed to compare how premotor and parietal stimulation affects performance across reach directions with different movement demands, in preparation for therapeutic application of TMS. Methods: 16 participants with chronic subcortical stroke performed planar reaches with the KINARM exoskeleton toward distal and proximal targets. Before movement, a 10-Hz triple-pulse TMS train was delivered over bilateral dorsal or ventral premotor cortex (PMd, PMv) or dorsomedial posterior parietal cortex (PPC) at subthreshold and supr","pubDate":"2026-10-22","url":"https://www.medrxiv.org/content/10.64898/2026.10.22.26365984v1?rss=1"},"indexado":"2026-10-22T21:54:18.823Z"}}
