Unimanual Versus Bimanual Motor Skill Learning in Acute and Chronic Stroke (MLAS6)

14. september 2026 oppdatert av: Pr Yves Vandermeeren, MD, PhD, University Hospital of Mont-Godinne

Comparison of Unimanual Versus Bimanual Motor Skill Learning (Proximal and Distal) After Stroke by Means of Robotics (REA²Plan® and Dextrain®) and Multimodal Brain Imaging (VLSM, DTI, NODDI, DIAMOND)

To test the capacity of healthy individuals, chronic and acute stroke patients to learn and retain a complex unimanual or bimanual motor skill, trained on the neurorehabiliation robot REAplan® et the Dextrain® device. The goals are (1) to compare head-to-head bimanual versus unimanual motor learning (in the proximal and distal upper limb, UL) during the acute - early subactue stage of stroke with robotics and (2) to identify the neural substrates associated with (and deficits in) unimanual versus bimanual motor control (proximal and distal) after stroke by means of multimodal brain imaging.

Detaljert beskrivelse

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

They will practice a task on the robot REAplan® (unimanual or bimanual version), requiring movements with the affected arm (unimanual version) and complex, coordinated movements with both arms (bimanual version). They will practice another task on the Dextrain® device, also in unimanual and bimanual version.

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