Wavelet analysis of cerebral oxygenation signal measured by near infrared spectroscopy in subjects with cerebral infarction.
Frequency‐specific functional connectivity related to the rehabilitation task of stroke patients
Analysis of the brain network patterns of stroke patients while performing a four-limb linkage rehabilitation training using the functional near-infrared spectroscopy (fNIRS) method suggested that the frequency-specific FC methods based on WPCO would provide a potential approach to quantitatively assess the effect of rehabilitation tasks.

The decreased effective connectivity levels among brain regions may be a marker of impaired cognitive function in the mild cognitive impairment group.
Decreased low-frequency brain effective connectivity in seafarers during voyages: a functional near-infrared spectroscopy study.
Investigation of the low-frequency brain effective connectivity in seafarers during voyages by using the coupling strength of functional near-infrared spectroscopy (fNIRS) imaging revealed that the Patient Health Questionnaire-9 scores were positively correlated with the Systolic blood pressure values, delta HbO2 values and EC levels, respectively.

The reduction of spontaneous oscillations in subjects with CI may suggest an increased stiffness in cerebral arterial vessels and indicates the possibility of applying spontaneous oscillation to assessing atherosclerosis in high risk subjects for CI based on the wavelet transform of NIRS signals.
The efficacy of median nerve electrical stimulation in rehabilitating post-stroke cognitive impairment and its mechanism
Electrical stimulation of the median nerve can help to improve cognition after a stroke and increases oxyhemoglobin concentration in the bilateral frontal lobes.
