Barthel Index Calculator - ADL Score

The Barthel Index is a clinical scale for describing how independently a person performs basic activities of daily living. It covers feeding, bathing, grooming, dressing, bowel control, bladder control, toilet use, transfers, mobility, and stairs. Each domain has defined response choices with point values based on the assistance required. This version totals those choices on the widely used 0 to 100 scale, where a higher score indicates greater functional independence. Clinicians commonly use the assessment in rehabilitation, neurology, geriatrics, stroke care, and discharge planning. The score provides a concise baseline and can help teams describe changes over time. It focuses on what the person actually does, not what they might be capable of under ideal conditions. Observation, reports from caregivers, and recent routine performance may all inform a rating. When performance varies, clinical protocols generally favor the lower, safer description unless a standardized local rule says otherwise. The domains are not equally weighted. Bathing and grooming contribute up to 5 points each, while transfers and mobility contribute up to 15 points each. This weighting reflects the original scale and should not be altered simply to make every activity count the same. Equipment may still be compatible with independence in some domains when the person sets it up and uses it without another person's help. Verbal prompting, physical assistance, and supervision should be considered according to the wording of each response. Interpretive bands vary among publications and institutions. This calculator labels scores from 0 through 20 as total dependence, 21 through 60 as severe dependence, 61 through 90 as moderate dependence, 91 through 99 as slight dependence, and 100 as independent. These bands summarize the total but do not replace the domain pattern. Two people with the same score may require help with very different tasks, creating different care, equipment, and safety needs. The Barthel Index is not a diagnosis, a complete disability assessment, or a prediction that stands alone. It does not evaluate cognition, communication, mood, complex household tasks, work, community participation, or every fall risk. Acute illness, fatigue, pain, environment, and available aids can influence observed function. Qualified professionals should combine the score with clinical examination, patient goals, caregiver information, and local guidance. Use this calculator to total an assessment consistently, document the date and circumstances, and review individual responses rather than relying only on the final number.
