Recruiting NA Stroke

New treatment option for Stroke

Official title Implantable Brain-Computer Interface for Upper-Limb Recovery After Stroke

ClinicalTrials.gov ID: NCT07477613

What this study is testing

What it's testing
The clinical investigation will take place in three phases: A pre-selection/selection phase to ensure that the patient (lesion, symptoms, ability of our tools to detect your movement intentions, etc.) is suitable for a six-month intensive rehabilitation program using Brain-Machine Interface. A second phase, consisting of implementing the intensive rehabilitation program, first in the traditional manner, without the Brain-Machine Interface (2 to 5 weeks), then, after implantation, with the Brain-Machine Interface (6 months).

Who can take part

Ages 18 to 70

You may be able to join if

  • Single unilateral stroke occurred 6 months to 18 months ago
  • Disabling motor deficit of upper limb

You likely can't join if
