What Is the Barthel Index?

The Barthel Index (BI) is the most widely used standardised measure of functional independence in activities of daily living in stroke rehabilitation and geriatric medicine worldwide. Developed by Florence Mahoney and Dorothea Barthel at the Maryland State Department of Health and published in Maryland State Medical Journal in 1965, it scores 10 basic ADL activities on a graduated scale with a maximum of 100 points (fully independent) and minimum of 0 (fully dependent). It has been validated in over 100 populations and translated into more than 30 languages.

Barthel Index vs Katz ADL — Key Differences

The Katz ADL uses a simple binary (independent/dependent) scoring — faster and better for screening. The Barthel Index uses graduated scoring with 3–4 levels per activity — more sensitive to partial independence and better suited for tracking rehabilitation progress over time. The Barthel is the standard outcome measure in stroke rehabilitation; the Katz ADL is the standard for geriatric functional assessment and care planning. Use Barthel for rehabilitation outcomes; use Katz for care needs assessment and SNF MDS requirements.

Stroke Rehabilitation Benchmarks

  • BI ≥ 85 at 3 months post-stroke predicts favourable long-term functional outcome and community reintegration
  • BI ≥ 60 at discharge from acute stroke unit is associated with successful return to community living in most patients
  • Admission BI as predictor — Barthel Index at admission to inpatient rehab predicts discharge destination, length of stay, and need for institutionalisation
  • BI change of ≥ 20 points during inpatient rehabilitation represents clinically significant functional recovery

Frequently Asked Questions

What is the maximum Barthel Index score?
The maximum Barthel Index score is 100 points, indicating full functional independence in all 10 ADL activities. A score of 100 does not necessarily mean the patient has no disability — it means they are independent in basic self-care. For example, a patient may score 100 on the Barthel but still be unable to live alone due to cognitive impairment or complex medical needs. The BI measures only basic ADL independence, not higher-order function or community integration.
How is the Barthel Index scored?
Each of the 10 activities is scored on a graduated scale reflecting the level of assistance required. Activities are weighted differently: Transfer and Mobility are worth up to 15 points each; Bowels, Bladder, Feeding, Toilet, Dressing, and Stairs are worth up to 10 points each; Grooming and Bathing are worth up to 5 points each. Total maximum is 100. Each activity is scored as the highest level the patient consistently achieves — not the best possible performance on a good day.
What Barthel Index score is needed for discharge home from stroke rehabilitation?
There is no universally agreed cut-off, but several benchmarks guide clinical decision-making. A Barthel Index of 60 or above at discharge from acute stroke care is generally associated with the ability to return to community living with support. A score of 85 or above is associated with more independent community living with minimal ongoing assistance. Scores below 40 at discharge typically indicate need for skilled nursing facility placement or very intensive home care. Always consider home environment, caregiver availability, and cognition alongside the BI score.
