Many patients retain upper-limb motor impairment following stroke. Most conventional rehabilitation techniques are aimed to improve motor intentional movement by repeated exercises. These techniques require attentional load and are responsible for significant fatigue that probably represents a limiting factor. Alternatively, the automatic control of action is now well documented. A rehabilitation method based on this principle could allow recovery of more natural movements.

Hypothesis: Stimulating automatic motricity improves upper-limb motor skills compared with a rehabilitation technique based on intentional movements.
