What is a Barthel Index?
The Barthel Index (BI) is a widely used outcome measure that assesses a person's ability to perform activities of daily living (ADLs). Developed by Mahoney and Barthel (1965), it was initially created to measure functional and physical disability in stroke patients. However, its usefulness has extended to a broader range of conditions, including:
- Musculoskeletal disorders
- Brain injury
- Mental disorders
- Multiple sclerosis
- Hospital discharge planning
- Nursing home care
The BI, a widely used measure, is a ranked scale with ten items, each focusing on a specific ADL. These include:
- Eating
- Bathing
- Grooming
- Dressing
- Bowel control
- Bladder control
- Toilet use
- Transfer (moving between sitting and standing)
- Mobility (on level surfaces)
- Stair climbing
Each item is scored based on the level of assistance a person requires to complete the task. Scores range from 0 (completely dependent) to 10 (completely independent). The total score (maximum score of 100) or the outcome measures reflect the patient's overall functional independence in daily living.
The core concept behind the Barthel Index is functional independence. This refers to a person's ability to manage daily tasks without assistance. The BI helps measure a patient's progress in functional recovery, which is regaining independence after an illness or injury.
Considerations in using the Barthel Index
While the Barthel Index is a valuable tool, it's essential to consider the following aspects:
- Psychometric properties: The BI has good internal consistency (Cronbach's alpha) and inter-rater reliability, but its validity for specific diseases may require further investigation.
- Ceiling and floor effects: The BI may not be sensitive to small changes in function for patients with very high or very low scores (ceiling and floor effects, respectively).
- Modified versions: The original Barthel Index may not capture some populations' full range of functional abilities. Modified versions, like the Modified Barthel Index (MBI), address these limitations.
It is important to remember that the Barthel Index does not assess instrumental activities of daily living (IADLs), which are more complex tasks like managing finances or using transportation. For a more comprehensive assessment, the BI can be used with other functional evaluation tools, such as the FIM (Functional Independence Measure) or the MDS (Minimum Data Set).
While the Barthel Index has its limitations, it remains a valuable tool for healthcare professionals working with patients who require rehabilitation following a stroke, brain injury, or other conditions that impact independent living.

How to use the Barthel Index
The Barthel Index is a helpful tool to assess a person's ability to manage daily activities without assistance. The following are the steps on how you can maximize this resource:
Step 1: Understand the purpose and components
The Barthel Index is widely used to measure disability and assess functional independence in ADLs. It consists of 10 items: personal hygiene, bathing, feeding, toilet use, dressing, bowel control, bladder control, transfers, mobility on level surfaces, and stair climbing.
Step 2: Prepare for assessment
Gather the necessary materials, such as the BI scoring form, pen or pencil, and assistive devices the patient typically uses. Ensure a quiet and comfortable environment for the assessment. Introduce the purpose of the assessment to the patient and obtain their consent for the direct observation process.
Step 3: Conduct the assessment
Observe the patient performing each ADL task or rely on self-report or caregiver input if direct testing is impossible. It's also important to note the activities that the patient can accomplish while carrying aid to assist them. When scoring each item, the scale typically ranges from 0 to 10, with some items having a maximum score of 15. The scoring criteria should be followed accurately to ensure consistency in assessment.
Step 4: Calculate the total score
Add up each item's scores to obtain the total BI score. The maximum score is 100, indicating complete functional independence. Lower scores indicate varying degrees of dependence.
Step 5: Interpret and document the results
Interpret the total BI composite score based on established guidelines, typically:
- 0-20: Total dependence
- 21-60: Severe dependence
- 61-90: Moderate dependence
- 91-99: Slight dependence
- 100: Complete independence
Document the results in the patient's medical record, including the total score, individual item scores, and any relevant observations or comments. Use the BI score and other clinical assessments to guide care planning, discharge planning, and treatment decisions, especially in stroke recovery.
Remember, the BI is a standardized tool, and proper training is recommended to ensure consistent and accurate administration and scoring (Quinn et al., 2011).

Scoring and interpretation
The Barthel Index is a widely used assessment tool that measures an individual's level of independence in performing ADLs. The scoring system is designed to evaluate the patient's functional abilities objectively.
The BI consists of 10 items, each scored on a scale ranging from 0 to either 10 or 15 points, depending on the specific task. The scoring criteria for each item are as follows:
- Feeding: 0 (unable), 5 (needs help), 10 (independent)
- Bathing: 0 (dependent), 5 (independent)
- Grooming: 0 (needs to help with personal care), 5 (independent)
- Dressing: 0 (dependent), 5 (needs help), 10 (independent)
- Bowel control: 0 (incontinent), 5 (occasional accident), 10 (continent)
- Bladder control: 0 (incontinent), 5 (occasional accident), 10 (continent)
- Toilet use: 0 (dependent), 5 (needs some help), 10 (independent)
- Transfers (bed to chair and back): 0 (unable, no sitting balance), 5 (major help), 10 (minor help), 15 (independent)
- Mobility (on level surfaces): 0 (immobile), 5 (wheelchair independent), 10 (walks with the help of one person), 15 (independent)
- Stairs: 0 (unable), 5 (needs help), 10 (independent)
The total BI score is calculated by summing the individual item scores, with a maximum possible score of 100, indicating complete independence in ADLs.
When would you typically use a Barthel Index?
The Barthel Index shines when understanding a patient's ability to manage ADLs is crucial. Here are some common scenarios where the BI becomes a valuable tool:
Assessing stroke recovery
Initially designed for stroke patients, the BI provides a clear picture of functional independence after a stroke. This helps guide therapy plans and track progress in regaining daily living skills.
Evaluating functional decline
The BI can be used for people with various conditions that might affect their ability to perform ADLs. This includes brain injuries, musculoskeletal disorders, or multiple sclerosis.
Planning hospital discharge
Knowing a patient's functional independence level helps determine if they require additional support at home or in a rehabilitation facility after discharge.
Monitoring progress in rehabilitation
The BI's simple scoring system allows for regular assessments, making tracking a patient's progress easy and adjusting rehabilitation strategies as needed.
What are the benefits of using the Barthel Index?
The Barthel Index may benefit patients and therapists by helping them gauge the capabilities of patients admitted to rehabilitation units or facilities.
Results can be discussed with the patient. If the patient can still improve, discussing results might help inspire them to improve and hopefully become fully independent with some, ideally all, of their ADLs.
The data produced by the Barthel Index is a valid measure that helps the patient visualize and understand the areas in their life where function has been reduced. Having access to this kind of information allows people to more accurately focus their time and effort on areas requiring improvement, hopefully leading to their maximum benefit and positive changes during the treatment process.

Commonly asked questions
Yes, the Barthel Index (BI) scoring can be considered relatively objective. The BI uses a standardized scoring system with clear criteria for each item, ranging from 0 (completely dependent) to 10 or 15 (completely independent). However, it is essential to note that the assessment still requires some subjective judgment, especially when observing the patient's performance or relying on self-report or caregiver input.
The Barthel Index is widely used to assess functional independence in activities of daily living (ADLs) across a variety of clinical settings and patient populations, including stroke patients, patients with musculoskeletal disorders, brain injuries, mental disorders, and multiple sclerosis. This can also be helpful in hospital discharge planning and nursing home care.
The Barthel Index is typically administered multiple times to assess a patient's progress, such as at admission, during treatment, and at discharge. Repeated use of the BI is reliable and responsive to changes in functional status. While a single administration of the BI can provide valuable information, it is generally recommended to use the BI on multiple occasions to track the patient's functional trajectory and guide treatment decisions.
