Method · Limits of application

Barthel/Mahoney 1965: 10 activities, sum 0–100 in multiples of 5; mobility ≥ 50 yards (45.72 m); excludes the modified Shah 1989 version

Use the rubrics of the adopted 0–100 version and record the time of functional assessment. The modified version studied by Shah in rehabilitation after stroke is not interchangeable, item by item, with the local original. The cited Brazilian validation still requires primary-source reading in this review. In the reprint of the 1965 text, the detailed mobility definitions use at least 50 yards, equivalent to 45.72 m, not more than 50 m. For bowel control, no accidents and using a suppository/enema without help if needed allow 10 points; needing help with a suppository/enema or having occasional accidents receives 5 points. When the criteria for 5 or 10 are not met, the reprint’s general rule assigns 0. Checking the sum does not certify complete equivalence of the other rubrics or the ability to live alone.
