Figure 5
Cortical changes at movement execution following the intervention. (A) and (B) depict current source density plots across the sensorimotor cortex Pre-Intervention (Left), Post-Intervention (Middle), and the observed intervention-induced difference (Right) for (A) Hand Opening on the table and (B) Hand Opening while Lifting in one participant. The Left hemisphere is the lesioned hemisphere. (C) and (D) contain box plots depicting cortical activity ratio Pre/Post Intervention for (C) Hand Opening on the table and (D) Hand Opening while Lifting. Regions include combined primary motor cortex and primary sensory cortex (M1/S1) and combined supplementary motor area and premotor area (SMA/PM) for both the ipsilesional (Blue) and contralesional (Red) hemispheres. Participants demonstrated a decrease in contralesional primary sensorimotor cortex activity for hand opening following the intervention (left) and an increase in ipsilesional primary sensorimotor cortex activity for hand opening while lifting following the intervention (right). * indicates p < 0.05.
