Implication

fNIRS may map passive motor activation; leaves open clinical translation to rehabilitation monitoring.

Structured PICO

Population

4 healthy right-handed male volunteers, mean age 32 years, with no history of neurological, physical, or psychiatric illnesses.

Intervention

Active movement (flexion/extension of right hand) and passive movement (via functional electrical stimulation) at 0.5 Hz.

Comparator

Rest phase and comparison between active and passive movements.

Outcome

Cerebral cortex activation (oxy-hemoglobin concentration changes) and effective connectivity (Granger causality) in the primary somatosensory cortex (S1), primary motor cortex (M1), and supplementary motor area (SMA).surrogate

Active and passive finger movements elicit different directional coupling in sensorimotor networks, with passive movement primarily driving S1 to M1 connectivity.
