Automatic Versus Intentional Movement Exercises to Enhance Arm Functions After Stroke

Hospices Civils de Lyon26 enrolled

Overview

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.

Outcomes

Primary Outcomes

Fugl Meyer assessment (upper extremity) of motor recovery following stroke

we are looking for a change in scores between the baseline session score (Day 1), and those collected during this follow-up session (Day 26).

Time frame: 2 weeks following the last day of the intervention (Day 26)

Secondary Outcomes

Fugl Meyer assessment (upper extremity) of motor recovery following stroke

we are looking for a change in scores between the baseline session score (Day 1), and those collected during each follow-up session

Time frame: immediately following the last day of the intervention (Day 12)

modified Ashworth scale

we are looking for a change in scores between the baseline session score (Day 1), and those collected during each follow-up session.
