Abstract : HANDS therapy was developed as a new therapeutic approach to facilitate the use of the affected upper extremity in daily living by combining closed loop EMG controlled neuromuscular electrical stimulation with a wrist splint for patients with moderate to severe hemiparesis. We found significant functional recovery and physiological changes following HANDS therapy. We cannot, however, apply HANDS therapy in patients whose paretic extensor EMG activities are not detected with surface electrodes. However, for such severe hemiparetic patients, we can apply Brain Machine Interface (BMI) to facilitate EMG activities of paretic finger extensors. After the BMI training, we found EMG activity in the affected finger extensors. Our BMI system is triggered by event related desynchronization (ERD) during motor imagery. Additionally, anodal tDCS can increase the amount of ERD of the affected hemisphere. Thus, BMI combined with anodal tDCS can improve the effectiveness of BMI training among severe hemiparetic patients. HANDS therapy, BMI and BMI combined with tDCS may offer promising options for the improvement of paretic upper extremity function among severe hemiparetic patients.
