Bimanual Motor Skill Learning Through Robotics in Stroke Survivors and Healthy Individuals
- Conditions
- Stroke
- Interventions
- Device: Bimanual motor skill learning with the REAplan(R) rehabilitation robot
- Registration Number
- NCT03974750
- Lead Sponsor
- University Hospital of Mont-Godinne
- Brief Summary
To test the capacity of healthy and chronic stroke patients to learn and retain a complex bimanual motor skill, trained on the neurorehabilitation robot REAplan (R) (bimanual version).
- Detailed Description
Over 3 consecutive days, healthy individuals and chronic stroke patients (1) will be evaluated and (2) will train on the neurorehabilitation robot REAplan(R).
They will practice several tasks on the robot REAplan (R) (bimanual version), requiring either movements with the affected arm (unimanual tasks) and 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, ...).

- Primary Outcome Measures
Name Time Method bi-SAT, bimanual Speed/Accurady Trade-off measured by the REAplan robot change between baseline (Day 1) and after training (Day 3) bimanual Speed/Accurady Trade-off: mathematical computation of the relationship bewteen speed and accuracy
bi-Force, bimanual Coordination factor measured by the REAplan robot change between baseline (Day 1) and after training (Day 3) bimanual forces, forces exerted in the wrong direction by each arm (Newtons)
bi-CO, bimanual Coordination factor measured by the REAplan robot change between baseline (Day 1) and after training (Day 3) bimanual Coordination factor, mathematical measure of the phase coherence between speeds of both arms
- Secondary Outcome Measures
Name Time Method bi-CO on bimanual REACHING (REAplan robot) change between baseline (Day 1) and after training (Day 3) bimanual Coordination factor, mathematical measure of the phase coherence between speeds of both arms
bi-smoothness on bimanual REACHING (REAplan robot) change between baseline (Day 1) and after training (Day 3) Smoothness of movement : Spectral Arc Length (SPARC)
BBT change between baseline (Day 1) and after training (Day 3) Box \& Blocks Test (timed transfert of blocks from one space to the other, 3 trials/hand)
bi-error on bimanual REACHING (REAplan robot) change between baseline (Day 1) and after training (Day 3) Error in centimeres or degrees during bimanual reaching
bi-SAT on bimanual REACHING (REAplan robot) change between baseline (Day 1) and after training (Day 3) bimanual Speed/Accurady Trade-off: mathematical computation of the relationship
bi-Force on bimanual REACHING (REAplan robot) change between baseline (Day 1) and after training (Day 3) bimanual forces, forces exerted in the wrong direction by each arm (Newtons)
whole-hand GF change between baseline (Day 1) and after training (Day 3) whole-hand Grip Force (GF) measured with a dynamometer, 3 trials/hand)
Visual Analog Scale for fatigue (VAS fatigue) change between baseline (Day 1) and after training (Day 3) Visual Analog Scale to evaluate fatigue = a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. Range : 0- 10.
