Alterations in the correlation coefficient between functional parameters [peak motion-related activation, peak resting-state functional connectivity (RSFC), and coupling strength] and Upper Limb Fugl-Meyer Assessment (UL-FMA) at the corresponding stage of progression. The peak motion-related activation and coupling strength during the acute stage was positively correlated to the UL-FMA scores at the corresponding stage (r = 0.50, 0.65; P = 0.025, P = 0.002, respectively). Red: correlation coefficient alteration between coupling strength and UL-FMA; green: correlation coefficient alteration between peak motion-related activation and UL-FMA; and blue: correlation coefficient alteration between peak RSFC and UL-FMA.
