About the Instrument
Originally developed by Rankin and later modified, the mRS is the most widely used global disability outcome measure in stroke research and clinical care.

Digital Administration
Delivered electronically through the PROMinsight platform as part of a digital patient-reported outcomes workflow.
Scoring / Reporting
A single ordinal grade (0–6) is assigned based on a structured assessment or interview; various certified assessment methods exist to standardise rating.
