Complete locked-in state.
Infra-red plus oxygen:
Communication!
Complete locked-in state is a condition where patients are suffering from motor paralysis but retain their mental processing abilities. The inability to control their own body movements has made communication with people suffering from this condition effectively impossible. However, by using functional near-infrared spectroscopy measure changes in frontocentral oxygenation patients were able to answer yes and no questions. Chaudhary et al, 2017.
