Bimanual Motor Skill Learning Through Robotics in Chronic Cerebellar Stroke Survivors and Healthy Individuals

Not Applicable
Active, not recruiting
Conditions
Healthy Individuals (Controls)
Chronic Cerebellar Stroke
Interventions
Device: Bimanual motor skill learning with the REAplan® rehabilitation robot
Registration Number
NCT04642599
Lead Sponsor
University Hospital of Mont-Godinne
Brief Summary

To test capacity of chronic cerebellar stroke patients and healthy individuals to learn and retain a complex bimanual motor skill, trained on the neurorehabilitation robot REAplan® (bimanual version).

Detailed Description

Over 3 consecutive days, healthy individuals and chronic cerebellar stroke patients (1) will be evaluated and (2) will train on the neurorehabilitation robot REAplan®.

They will practice several tasks on the robot REAplan® (bimanual version), requiring either movements with the affected arm (unimanual tasks) or complex, coordinated movements with both arms (bimanual tasks).

In addition, several "classical" clinical scales and tests will be used to evaluate overall motor-sensory-cognitive functions (clinical tests, questionnaires, ...).

Hand/digits motor function will be also evaluated with the kinetic device DexTrain®.
