This study examines express visuomotor responses (EVRs) in Parkinson's Disease patients and healthy controls during step initiation, finding EVRs are preserved in low postural demand but absent in high demand, with disease severity affecting EVR magnitude.

This study examines how aging and postural stability affect express visuomotor responses (EVRs) during reaching tasks, finding that elderly participants show smaller, delayed EVRs and slower movements, independent of postural demands.

The paper examines cortical dynamics during rapid stepping movements under different postural demands, finding greater cortical involvement in high-demand steps.

This study investigates how express visuomotor responses (EVRs) in lower limbs interact with postural control during stepping, finding that EVRs are suppressed under high postural demands.
