When and where was the research paper published?

It was published on May 28, 2026, in the international journal 'Journal of Cerebral Blood Flow & Metabolism.'

Why do clinical studies on motor recovery after stroke often fail to show consistent results?

The paper points out a mismatch between the specific goals of the treatment and the overall outcome measures (such as mRS or Barthel Index) used to evaluate recovery.

What framework does the research team recommend for evaluating recovery?

They recommend selecting evaluation measures based on the WHO's International Classification of Functioning, Disability and Health (ICF), categorized into three levels: body function, activity, and participation.

What new evaluation concept is proposed instead of relying solely on statistical significance?

The research proposes the use of Minimal Clinically Important Difference (MCID), which reflects changes meaningful to the patient's daily life.
