Barthel Index Calculator
Calculate the Barthel Index score to assess a patient's functional independence in activities of daily living (ADL).
Formula
Score = sum of 10 ADL domain scores (range 0–100)
- Scoring: 91–100 = Independent; 61–90 = Mild dependence; 41–60 = Moderate; 21–40 = Severe; 0–20 = Total dependence.
- Original Barthel ADL Index (Mahoney & Barthel, 1965).
- Used in rehabilitation settings for functional outcome measurement.
