We used near-infrared spectroscopy (NIRS) to measure the cerebral oxygenation and blood volume of nondisabled subjects and subjects with traumatic brain injury (TBI) performing a rhythmic handgrip exercise on two separate occasions.

Both groups' cerebral oxygenation and blood volume increased during the exercise. The changes were similar for both trials and cerebral oxygenation was significantly lower in subjects with TBI than in nondisabled subjects.

These findings indicate that NIRS reliably and noninvasively evaluates cerebral oxygenation and blood volume changes during motor function and can monitor cerebral oxygenation recovery during rehabilitation.
