This study aimed to assess the effect of altered strength sound limb on hemodynamics in affected brain stroke patients. We recruited 20 patients detect changes HbO concentrations bilateral prefrontal cortex (PFC), sensorimotor (SMC), and occipital lobe (OL). performed functional near-infrared spectroscopy (fNIRS) oxyhemoglobin (HbO) regions interest (ROIs) cerebral hemispheres while they 20%, 50%, 80% maximal voluntary contraction (MVC) levels handgrip tasks with unaffected hands. The results suggest that when 50% MVC force, SMC hemisphere was strongly activated change concentration similar MVC. When force MVC, showed a more proportional activation than at Overall, this research suggests poor upper function should perform motor training their hands grip task activate ipsilesional hemisphere.
