Sensory Mechanisms of Manual Dexterity Recovery After Stroke: a Prospective Cohort Study of Prediction and Cerebral Correlates
Sponsor: Centre Hospitalier St Anne
Summary
In the proposed research, we will assess motor and sensory functions of the hand using clinical tests and a tool designed to measure manual dexterity combined with vibrotactile stimulation. We will also evaluate the integrity of brain structure and function using MRI.

Interventions
Haptic stimulation device
Both patients and healthy participants will perform manual dexterity tasks using the Dextrain Manipulandum. In addition, they will receive finger vibrations delivered via rings that we have previously developed. These vibrations will have a frequency of 150 Hz and will be delivered for a duration of 150 ms.
Brain MRI
Subjects and patients will undergo anatomical, resting-state functional, and diffusion brain MRI sequences.
