Influence of Handedness on Upper Limb Recovery

Condition(s) studied

Investigational drug(s) / intervention(s)

evaluation: Patients will be evaluated at baseline for Edinburgh Handedness Inventory Laterality Quotient. Patients will be seen again at 6 months as part of their standard post-stroke consultation at Orléans University Hospital by a neurologist from the neurology department. In conjunction with this consultation, an assessment specific to this research study of the FMA-UE and SAFE scores will be carried out by a physiotherapist from the department.

Study summary

This prospective, single-center observational study evaluates whether handedness is associated with upper-limb motor recovery after a recent unilateral stroke. Adults admitted to the stroke unit with a confirmed unilateral stroke within 5 days are included if they do not object to participation. Upper-limb impairment is assessed early after stroke and at 6 months using standardized clinical scales. Handedness is determined by self-report, and the Edinburgh Handedness Inventory is administered when feasible. The main hypothesis is that left-handed participants may show better upper-limb motor recovery at 6 months than right-handed participants, potentially due to differences in brain motor network lateralization.

Eligibility

Primary outcome measure(s)

• Fugl-Meyer Assessment for Upper Extremity (FMA-UE) Score — month 6
  Upper-limb motor impairment measured using the Fugl-Meyer Assessment for the Upper Extremity (FMA-UE) at 6 months post-stroke. Scores range from 0 to 66, with higher scores indicating less impairment. Primary analysis is performed among participants with baseline FMA-UE less than 66.
