About this study

Official title: Accident Vasculaire cérébral et Apport Des Neurotechnologies individualisées Chez la Personne Avec Une hémiparésie Chronique : Une Etude Clinique Prospective Visant à Restaurer la mobilité du Membre supérieur

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Paretic upper limb functional electric stimulation through RehaStimDevice

    The stimulation will activate upper limb muscles to perform motor rehabilitation exercises for the upper limb with the help of the Gloreha Sinfonia robotic glove that will assist-as-needed hands movements. Motor intention will be detected by a BCI (Brain Computer Interface) from the non-invasive measure of brain activity by using electroencephalography.

    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.

  • Non-invasive transcranial current stimulation through DC-StimulatorDevice

    Non-invasive brain stimulation in the form of transcranial direct current stimulation will be provided in addition to the previous intervention.

Study groupRoleWhat they receive
Group AExperimentalPatients belonging to group A will start intervention I, immediately after baseline. We will recruit about 25 for group A (randomization will take into account the two to one study design) in order to have about 20 patients in Group A that will complete the study.
Receives: Device: Paretic upper limb functional electric stimulation through RehaStim; Device: Non-invasive transcranial current stimulation through DC-Stimulator
Group BExperimentalPatients belonging to group B will follow an observation period (max. 3 months) before starting intervention I. We will recruit about 15 patients for group B (randomization will take into account the two to one study design) in order to have about 10 patients in Group B that will complete the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in functional improvement of upper limbs along training sessions

    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.

    Measured: 10 months average

  2. Change in speed and coordination of the affected side

    Measurement of speed and coordination of the affected side are performed using FMA modified score, max 54.

    Measurements are performed every second training session.

    Measured: 10 months average

  3. Change in sensorimotor status in the two upper limbs

    Measurement of sensorimotor status in the two upper limbs, using Fugl-Meyer (FMA) scale (0-66).

    Measurements are performed at the evaluation visit.

    Measured: 10 months average

  4. Action Reach Arm Test (ARAT)

    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.

    Measured: 10 months average

  5. Fatigue Visual Analog Scale (VAS)

    Measurement of fatigue is made with the Visual Analog Scale (VAS; 0-100). Measurements are performed every second training session.

    Measured: 10 months average

  6. Rivermead Assessment of Somatosensory Performance (RASP)

    Somatosensory function are measured with RASP (RASP; 0-210) in the two upper limbs.

    Measurements are performed at the evaluation visit.

    Measured: 10 months average

Secondary outcomes (1)
  1. Brain stimulation effectiveness in BCI-aided motor therapy

    The measurement of the effectiveness of brain stimulation is measured by FMA scores of all patients at initial, inter-intervention and final evaluation. This measurement is made between the end and the beginning of each intervention for each patient.

    Comparison is made by using one-way ANOVA if data normally distributed, or Kruskal Wallis test if otherwise. Secondary analysis measures are calculated for each patient once they complete the study. It will consist in the evaluation of effectiveness of BCI-aided motor therapy without and with brain stimulation. Group comparison is done with inferential statistics for full and partial populations. Similar comparisons and judgement criteria are applied for clinical scales and questionnaires.

    Measured: 10 months average
