Reinforced Feedback in Virtual Environment "RFVE"


Phase N/A Results N/A

Trial Description

The aims of the study is to explore whether the rehabilitation of the upper extremity performed in interaction with a virtual environment could improve motor function in post-ischemic and post-haemorrhagic stroke subjects with hemiparesis, in comparison to the traditional neuromotor rehabilitation treatment.



  • Reinforced Feedback in Virtual Environment (RFVE) Device
    Other Names: Virtual Reality Rehabilitation System (VRRS)
    Intervention Desc: The patients allocated to RFVE group, will be treated using the "Virtual Reality Rehabilitation System" (VRRS). During the virtual therapy the subject will be seated in front of the wall screen grasping a sensorized real object with the affected hand. If the grasp is not possible the sensors will be fixed on a glove worn by the patient. The real object held by the subject, equipped with electromagnetic sensors, is matched to the virtual handling object. Thereafter, the patient moved the real object (e.g. ball) following the trajectory of the corresponding virtual object displayed on the computer screen in accordance with the requested virtual task.
    ARM 1: Kind: Experimental
    Label: Reinforced Feedback in Virtual Environment
    Description: During the experiment, patients in the RFVE training group (Reinforced Feedback in Virtual Environment) will receive 1 hour of virtual reality-based therapy by means of RFVE and 1 hour of TNR treatment (Traditional Neuromotor Rehabilitation). Both treatments will last 1 hour a day, five days weekly for four weeks. The treatment is focused on motor function impairment of the upper extremity.
  • Traditional Neuromotor Rehabilitation Other
    Intervention Desc: The patients randomized to the Traditional Neuromotor Rehabilitation group will be asked to perform exercises for postural control, exercises for hand pre-configuration, exercises for the stimulation of manipulation and functional skills, exercises for proximal-distal coordination. All the exercises will be performed with or without the assistance of a physiotherapist. The upper limb motricity will be trained with progressive complexity. To achieve the requested goal (in a horizontal or vertical plane) patients will be asked to perform various movements, for example: shoulder flexion and extension, shoulder abduction and adduction, shoulder internal and external rotation and shoulder circumduction, elbow flexion and extension, forearm pronation and supination, hand grasping-release and clenching into a fist.
    ARM 1: Kind: Experimental
    Label: Traditional Neromotor Rehabilitation
    Description: The TNR training group (Traditional Neuromotor Rehabilitation) patients will be treated totally for two hours daily by means of a TNR programme. The treatment will last 4 weeks.
