What is the ABC Scale?
The Activities-specific Balance Confidence Scale, or , is a measuring tool used to assess how a person perceives their balance. It’s a self-report scale, so the answers will be given by whoever is engaging with the scale.
The ABC Scale, developed in 1995 by L.E. Powell and A.M. Myers, aims to gauge individuals' confidence in performing ambulatory activities without the fear of losing balance and falling. Participants assign a numerical value that reflects their level of certainty in their ability to complete these tasks successfully.
This measuring tool is primarily utilized for evaluating elderly individuals, patients undergoing rehabilitation following injuries, and those managing neurological conditions. Healthcare professionals who incorporate this tool into their assessment repertoire utilize it to assess the impact of balance issues on their patients' ability and confidence to perform specific activities. The results obtained from these scales inform the need for additional assessments to comprehensively evaluate patients and inform their treatment plans.

How to use the ABC Scale
The ABC Scale is a simple clinical tool that can be used in two ways:
- The healthcare professional using it can conduct an interview and ask the patient how confident they are when performing certain activities. The professional will simply mention one activity at a time and have the patient rate themselves.
This takes more time than the second option, but it allows the professional to ask the patient to expound on specific answers, especially if the self-ratings are low.. This method also accounts for patients who cannot write because of certain conditions.
- If the patient can write, you can hand it to them so they can answer the scale independently. This is the quicker method because it can be completed within a few minutes, provided that the patient has a good idea of how confident they are when performing each item.
Either way, the patient will answer by rating each item with anything from 0% to 100%. The choices are always increments of ten (e.g., 10%, 20%, 30%, and so on).
The scale’s main question is: “How confident are you that you will not lose your balance or become unsteady when you…” and the items that follow it will complete it. Here are examples of what they will need to answer:
- …walk around the house?
- …stand on your tiptoes and reach for something above your head?
- …walk up or down a ramp?
- …are bumped into by people as you walk through the mall?
- …walk outside on icy sidewalks?
Beside each item is an empty box where they can write down their self-ratings.
To calculate the score, you simply need to add up the total score first, then divide it by 16, which is the total number of items on the scale.
To interpret the score, you just need to refer to these:
- A score of 49% or lower means that they have a low level of physical functioning
- A score of 50% to 80% means that they have a moderate level of physical functioning
- A score of 81% or higher means that they have a high level of physical functioning
- A score of 67% or lower means they have a substantial risk of falling
ABC Scale Example
Now that you know the basic gist of what the Activities-specific Balance Confidence Scale is all about, what kinds of questions it has, how it’s answered, how to score it, and how to interpret the findings, it’s time to see what it looks like. The template we have simply has the questions in a table, and each item has a blank box where the person engaging with it can write down their self-rating in increments of 10. There’s even a total score section at the bottom so you can write down the total score.
What we added is an Additional Comments Box. It’s an optional part of the template, but if the healthcare professional using it conducts the questionnaire like an interview and asks the patient to explain their ratings, they can write them down in the box! We believe this is a good way to take notes for reference when creating a treatment plan.

When is it best to use the ABC Scale?
The Activities-specific Balance Confidence Scale is most effective when assessing a patient's balance, particularly when they have experienced a recent fall.
Consider an elderly patient who, although not in a life-threatening condition, is now at a greater risk of falling. They feel frustrated with their current circumstances. Explain the ABC Scale and allow them to independently answer the questions if their motor skills allow, or conduct an interview-style assessment.
If the patient expands on their answers, combine this information with their score to create a personalized treatment plan that focuses on restoring their functional independence to a more favorable level.
In addition, the ABC Scale can complement other assessments that evaluate a patient's fall risk. By combining the results of these assessments with those of the ABC Scale, appropriate interventions and strategies for fall prevention can be determined and incorporated into the patient's treatment plan.
What are the benefits of using the ABC Scale?
It can help professionals gauge the risk of falling their patients have.
The ABC Scale was developed to assess an individual's confidence in maintaining balance and preventing falls during specific activities. To evaluate this, the scale relies on the patient's self-assessment.
Although this introduces subjectivity to the scale results, it is not inherently negative. In fact, it encourages active patient involvement in the assessment process, which holds great significance for healthcare professionals working with elderly patients, individuals in rehabilitation, and those with neurological conditions. By considering how patients perceive themselves, healthcare professionals can create personalized care and treatment plans tailored to their specific needs.
It can help set rehabilitation goals.
Healthcare professionals who utilize our template can leverage the additional comments box to encourage patients to elaborate on their self-ratings. While the ratings provide valuable insights for professionals to prioritize their focus, obtaining more nuanced patient answers can offer a deeper understanding. These nuanced answers will aid in determining the functional goals that professionals and patients should concentrate on, enabling the development of the necessary treatments and interventions to facilitate goal achievement.
It can be used to monitor progress over time.
You can reuse the ABC Scale during regular checkups.By frequently assessing your patient's self-ratings and observing increased confidence in performing specific activities, you can confidently conclude that your plan is effective and their recovery is progressing well. However, if there is no improvement, it may be necessary to modify your plan and evaluate the impact of these adjustments.
How can Carepatron help with physical therapy-related work?
If you’re a physical therapist, geriatrician, neurologist, or an adjacent healthcare professional, then we believe you’ll have the time of your life exploring the Carepatron platform. We have a bunch of features that we believe are going to help you streamline your workflows, improve your work, and more!
We’d highlight our resource library. It’s one of our most proud features. It houses clinical resources covering numerous fields and topics, including physical therapy and neurology. This ABC Scale and template are part of this library.
Since the ABC Scale focuses on a person's confidence when it comes to maintaining balance when performing certain ambulatory activities, we’d like to emphasize that the scale isn’t the only tool you can use to assess their balance and risk of falling. We have other assessments that can help you do that, some of which require effort from the patient. Such assessments include the Parkinson’s Balance Test, 30-second Sit-to-Stand, and the Timed Up and Go Test. Take your time to check out our library, and you’ll find more assessments to add to your roster. They’re all for free, too, so download as much as you want and need!
