To review the validity and reliability of the modified Rankin Scale as an instrument for measuring outcomes in clinical trials of new stroke therapies.
Synthesized published psychometric evidence evaluating the modified Rankin Scale across stroke populations.
Evaluated the tool's clinical consistency, construct validity, and sensitivity to therapeutic intervention effects.
Multiple lines of evidence confirm the measurement validity and inter-rater reliability of the modified Rankin Scale.
Data demonstrate that the scale reliably captures meaningful post-stroke functional recovery and serves as a valuable primary endpoint for evaluating emerging stroke treatments.
