Transcranial Direct Current Stimulation and Robotic Therapy in Upper Limb Motor Recovery After Stroke

As for transcranial direct current stimulation a HDC kit (ATES/EB NEURO, Firenze, Italy) will be used as device. It is a new device generation of stimulator able to provide an effective stimulation pattern.

As robotic device the InMotion wrist robot (Interactive Motion Technologies Inc., Watertown, MA, USA) will be used. It is an end-effector robotic device able to assist as needed the wrist movements.

Inclusion criteria

• upper limb hemiparesis;
• cognitive and speech abilities sufficient to understand instructions and to provide informed consent;
• absence of intense pain due to passive wrist mobilization assessed by VAS < 3 (range 0-10);
• ability to provide written informed consent.

Exclusion criteria

• previous epilepsy seizures;
• severe electroencephalographic anomalies;
• previous neurosurgery interventions involving metallic elements placement;
• ongoing anticonvulsant drugs treatment
• inability to keep sitting posture;
