The Barthel Index is one of the most commonly used tools in medical practice for assessing the level of patient independence in performing basic day-to-day activities. This index is especially important in rehabilitation medicine, the care of the elderly, as well as in the assessment of patients after stroke, spinal cord injuries and other conditions that affect motor and functional abilities.
Barthel’s index measures a person’s ability to independently perform ten basic functions, such as feeding, bathing, dressing, using toilets and moving. Based on the points that the patient receives, experts can determine the level of his dependence on the help of other people and plan the appropriate form of treatment, rehabilitation or care.
Precisely because of its simplicity, reliability and speed of application, the Barthel Index has become the standard in numerous hospitals, nursing homes and rehabilitation centers around the world. This article provides all the key information about what Barthel’s index is, how it was created, how it is used and what are its advantages and limitations in everyday clinical practice.
What is Barthel’s index and what is it for?
Barthel’s index is a standardized tool used to assess a person’s functional independence, that is, his ability to independently perform the basic activities of everyday life. It was first developed in 1965 by Dorothea Barthel and Florence Mahoney, with the aim of assessing the patient’s ability to function independently after an illness, injury or in the process of rehabilitation.
The index consists of ten categories that cover key daily functions: feeding, bathing, personal hygiene, dressing, control of stool and urine, use of toilets, transfer from bed to chair, walking and climbing stairs. Each function is scored according to the level of help that the patient needs – from complete dependence to complete independence – and the total number of points gives insight into the overall level of functionality.
The Barthel Index serves healthcare professionals as the basis for making decisions about the type and intensity of therapy, the need for home care or placement in institutions, as well as to monitor the progress of patients during rehabilitation. In addition, it is used in research to compare treatment outcomes of different groups of patients in a standardized manner.
The history and development of Barthel’s index
The Barthel Index was first introduced in 1965 in the United States, as a result of the work of Dorothea Barthel and Florence Mahoney at Maryland State Medical Care Center. Their goal was to develop a simple but effective tool that would enable an objective assessment of patients’ ability to perform basic daily activities independently, especially after stroke or other neurological conditions.
Initially, the index was designed for the needs of experts in physical medicine and rehabilitation, but over time, its application spread to other medical areas – including geriatrics, neurology, long-term care and assessment of the needs for institutionalization of patients.
Over the years, Barthel’s index has experienced several adjustments and variations. There are shorter and extended versions, and sometimes a modified Barthel index is used, which includes additional guidance for rating and better reliability among different estimators. Despite these changes, the basic concept remained the same – to enable a simple and consistent assessment of patients’ independence.
Thanks to its clarity, practicality and reliability, the Barthel index is still considered one of the most important tools in the assessment of the functional status of patients and is included in numerous clinical guidelines and protocols around the world.
How is Barthel’s assessment carried out?
Barthel’s assessment is conducted through a structured questionnaire that includes ten basic activities of everyday life. Each activity is graded with points, depending on how much the patient is able to perform it independently or how much help he needs. The total number of points can vary, but most often the maximum sum is 100, which indicates complete independence.
The ten activities that are evaluated are:
- Feeding
- Bathing
- Personal hygiene (face washing, combing, shaving)
- dressing
- Chair control
- Urine control
- use of toilets
- Transfer from bed to chair and vice versa
- walking (or moving in a wheelchair)
- Climbing and going down stairs
Each of the mentioned activities carries a certain number of points (eg 0, 5, 10 or more), depending on the level of help the patient needs – from complete dependence to complete independence. The assessment can be carried out through an interview with a patient, interviews with his family or guardians, but also through immediate observation during a stay in a hospital, home or home environment.
The total result is interpreted as follows:
- 0–20 points: a completely dependent patient
- 21–60 points: heavy addiction
- 61–90 points: Moderate dependence
- 91–99 points: Mild addiction
- 100 points: completely independent patient
Barthel’s assessment is usually used in patients’ admissions, during rehabilitation and at discharge, to monitor the change in functional status over time. Due to its simplicity and speed, it is often the first choice of experts for a quick but reliable assessment of the level of independence.
Applying Barthel’s Index to Practice
Barthel’s index is widely used in everyday clinical practice, especially in rehabilitation medicine, neurology, geriatrics, and long-term care. Its main function is to assess the level of functional independence of the patient, that is, how much a person can live independently without the help of another person. Based on this result, decisions can be made about the type of treatment, rehabilitation and necessary care.
The most common applications of Barthel’s index include:
- Assessment of hospital admission and discharge – The index is used to determine the patient’s initial condition and later to assess progress after therapy or rehabilitation.
- rehabilitation planning – It helps experts to determine which activities the patient still cannot perform independently and where therapeutic intervention is needed.
- Decision on accommodation – Based on the results, it can be decided whether the patient will be able to return home after treatment, whether he needs home care or institutional accommodation.
- Evaluation of treatment effectiveness – The results of the index are used to measure the improvement of functional status over time, which evaluates the success of the therapy.
- Research and statistical analysis – In many studies, it is used as a tool for objectively measuring the level of independence of patients with different diagnoses.
Barthel’s index is especially important in the care of the elderly, in whom preservation of independence is crucial for the quality of life. It is also used in patients after stroke, trauma, neurological diseases, orthopedic operations and chronic conditions.
Due to its simplicity, it does not require special equipment or much time to spend, which makes it suitable for use in both hospital and outpatient conditions – including health centers, homes for the elderly and home visits.

Advantages and limitations of this index
The Barthel Index is one of the most commonly used tools for assessing the functional capacity of patients, precisely because of its simplicity and practical application. However, like any diagnostic tool, it has its advantages, but also certain limitations that should be aware of when used in clinical practice.
Advantages of Barthel’s index:
- Ease of application
Barthel’s index is easy to understand and quick to apply. The assessment takes only a few minutes, and does not require specialized equipment or complex procedures. - High reliability and reproducibility
The results are consistent even when the assessment is carried out by different healthcare professionals, provided they are well acquainted with the rules of scoring. - applicable in different environments
It can be used in hospitals, homes for the elderly, rehabilitation centers, but also at home, which enables widespread use in various health systems. - Usefulness in tracking progress
The index can be used to monitor the patient’s progress over time, compare the condition before and after treatment, and assess the efficacy of therapy or rehabilitation. - An objective assessment for care planning
It helps healthcare professionals and families in making decisions about further care, accommodation, or needs for help in a home environment.
Barthel Index Limitations:
- not cover all aspects of everyday life
The index focuses on basic physical functions, but does not include cognitive abilities, emotional state or more complex activities (eg financial management, food preparation). - subjectivity of assessment
In some activities, different interpretations of scoring may occur, especially if it is not clearly defined how much help the patient actually needs. - does not distinguish qualitative differences
Although two patients may have the same number of points, their level of independence in reality may be different – the index does not take into account speed, effort or security when performing tasks. - Limited sensitivity in mild damage
In patients with minor or subtle functional difficulties, the index may not detect the problem because it uses a rough scoring scale. - Less applicable to younger population
Although it is beneficial for the elderly and patients with major impairments, it is less sensitive in younger people with mild difficulties in their daily functioning.
In conclusion, Barthel’s index remains an extremely useful tool in clinical practice, but its use is often combined with other instruments and assessments to give a complete picture of the patient’s health and functional condition.
