NIRS signals and VMR pattern for subject B – 2nd test. Time course of the O₂Hb and CO₂Hb concentration signals for subject B (post-stroke subject) during BH (left panel) and bidimensional VMR pattern (right panel). Data are realtive to the second test, i.e. after one year of drug and logopedic theraphy. The NIRS signals reveal an little increase in the O₂Hb concentration that was not observable in previous examination; the 2D pattern shows that a functional response is present since O₂Hb increases while CO₂Hb is kept at low levels. This changes in the VMR data are in accordance with the clinical evaluation, which reported an improvement in motor and phasic scores.
