Summary

The purpose of this study is to tested the effect of combination of a paired associative stimulation of two functional interconnected areas of the cerebral cortex (posterior-parietal cortex and primary motor cortex) with robot-assisted therapy in the recovery of upper limb after stroke.

Conditions

Interventions

DEVICE

Cortico-cortical stimulation plus robot-assisted therapy

15 sessions of cortico-cortical stimulation between the PPC and the M1 of the lesioned hemisphere and robot-assisted therapy. Paired-pulse stimulation (PAS) technique, with 5ms inter-stimulus time between the two areas (PPC to M1), will be done through two high-power Magstim 200 machines (Magstim® Rapid²). To stimulate the M1 area, the coil will be placed tangentially to the scalp at a 45° angle to the midline, to stimulate the PPC area the center of the coil will be positioned over P4 (10-20 EEG system) tangentially to the skull with the handle pointing downward and slightly medial (10°). Robot-assisted therapy will be performed with an Armeo® Power II (Hocoma), an integrative system composed by a robotic exoskeleton device connected to a laptop for the audio-visual biofeedback for the upper limb therapy.

DEVICE

Sham cortico-cortical stimulation plus robot-assisted therapy

15 sessions of sham cortico-cortical stimulation between the PPC and the M1 of the lesioned hemisphere and robot-assisted therapy. Sham paired-pulse stimulation (PAS) will be done through two high-power Magstim 200 machines (Magstim® Rapid²). To simulate the real stimulation, the coils will placed in the same sites with different inclination respect to the scalp (90°). Robot-assisted therapy will be performed with an Armeo® Power II (Hocoma), an integrative system composed by a robotic exoskeleton device connected to a laptop for the audio-visual biofeedback for the upper limb therapy.
