Abstract
New technologies for rehabilitation involving Augmented Reality (AR) as a complement to conventional therapy
have appeared in recent years. An earlier study for shoulder
rehabilitation using the AR NeuroR computer system showed
improved clinical outcomes for stroke patients. This study aims
to analyze a proposed protocol to measure possible changes
in functional brain connectivity associated with the use of the
NeuroR system in the context of shoulder motor rehabilitation
of post-stroke subjects. A pilot study was conducted with a poststroke patient, using resting-state functional magnetic resonance
imaging (RS-fMRI). RS-fMRI signals were acquired pre and post
use of the NeuroR system (pre-test and post-test), integrated
into the patient’s rehabilitation program. Functional connectivity
analysis of RS-fMRI was performed using the motor area as seed.
he maximum connectivity value in the pre-test occurred in the
ipsilesional parietal region while the maximum in the post-test
was located in the ipsilesional frontal region. It was observed
that the regions strongly associated with motor activity had
higher connectivity values at post-test compared to pre-test. The
proposed protocol is suitable and safe for verifying if functional
brain connectivity was changed after the rehabilitation program
with NeuroR training, indicating a possible neuroplasticity effect.
Tests with a larger number of patients are still necessary.
