简要总结
This study aims to evaluate safety, tolerability and efficacy of a new treatment for upper limb motor rehabilitation after severe stroke using non-invasive neurotechnologies. The investigational system is used alone or coupled with brain stimulation provided by transcranic direct current stimulation.
详细描述
This study aims at providing two interventions:
In the first intervention, a brain computer interface able to non-invasively detect motor intention from the non-invasive measure of brain activity by using electroencephalography (BrainVision, V-amp) activates a robotic glove (Gloreha Sinfonia, Idrogenet Srl) that will assist-as-needed hand movements and paretic upper limb functional electric stimulation (RehaStim, Hasomed). The latter will activate upper limb muscles to perform motor rehabilitation exercises for the upper limb. The motor rehabilitation exercises include upper limb and hand mobilization and functional tasks, such as hand open/closing, wrist flexion/extension, and reach and grasp a cup, keep and release.
In the second intervention, non-invasive brain stimulation (DC-Stimulator, NeuroConn) in the form of transcranial direct current stimulation will be provided in addition to the previous intervention.
Each participant will perform a minimum of 11 rehabilitative sessions for the first intervention and a minimum of 11 rehabilitative sessions for the second intervention, for a total minimum of 22 rehabilitative sessions. If the participant recovers with the intervention, the relative rehabilitative session continues to be proposed until patients will reaches a "plateau". The intervention will switch from 1 to 2 if the participant does not improve anymore with the 1st intervention. If the patient does not improve anymore with the 2nd intervention the interventional part of the trial will be finished. The intervention(s) will terminate also if the participant continues to progress after 6 months of inclusion. As the study is especially designed for personalization of intervention for every patient, it is not possible to determine a priori the number of sessions for each participant, because they depend on the response of each participant to the intervention. The duration of each rehabilitative visit is about two and half hours.

结局指标
主要结局
Change in functional improvement of upper limbs along training sessions
时间窗: 10 months average
Measurement of improvement before and after training of upper limb, using Fugl-Meyer (FMA) scale (0-66). FMA is a stroke specific index to estimate motor function. Measurements are performed every second training session and at the evaluation visit.
Change in speed and coordination of the affected side
时间窗: 10 months average
Measurement of speed and coordination of the affected side are performed using FMA modified score, max 54. Measurements are performed every second training session.
Fatigue Visual Analog Scale (VAS)
时间窗: 10 months average
Measurement of fatigue is made with the Visual Analog Scale (VAS; 0-100). Measurements are performed every second training session.
Rivermead Assessment of Somatosensory Performance (RASP)
时间窗: 10 months average
Somatosensory function are measured with RASP (RASP; 0-210) in the two upper limbs. Measurements are performed at the evaluation visit.
Change in sensorimotor status in the two upper limbs
时间窗: 10 months average
Measurement of sensorimotor status in the two upper limbs, using Fugl-Meyer (FMA) scale (0-66). Measurements are performed at the evaluation visit.
Action Reach Arm Test (ARAT)
时间窗: 10 months average
Upper limb functions changes measured by the ARAT test (ARAT scale: 0-57) in the two upper limbs. Measurements are performed at the evaluation visit.
