Thumb pain can be more than just annoying—it can make everyday tasks, like opening jars or gripping objects, feel almost impossible. If you have arthritis in your thumb, there’s hope for clearer answers and better solutions. Recent research highlights how doctors are working to improve how thumb arthritis, specifically rhizarthrosis, is diagnosed and treated in Brazil.
Here are three key takeaways:
- Doctors translated and adapted a helpful questionnaire used for thumb arthritis into Portuguese.
- The new version of the questionnaire is accurate and reliable for assessing Brazilian patients’ symptoms and challenges.
- This tool could make it easier to track patient progress after treatment.

What is rhizarthrosis?
Rhizarthrosis is a fancy word for arthritis affecting the base of your thumb. Arthritis happens when the cushioning between your joints wears down. For your thumb, this can make everyday movements (like gripping a pen or opening a door) painful.
Why was this study done?
You may be wondering why this research matters. Well, treating rhizarthrosis can be tricky because there’s no clear method for doctors to measure how effective a treatment is—or how much it’s helping the patient. Think about it: how can you tell if your thumb is getting better? That’s why this study focused on improving how thumb arthritis symptoms and disabilities are tracked, specifically for Brazilian Portuguese speakers.
How was the TASD translated for Brazil?
The research team used a well-defined process to adapt an important questionnaire—the Trapeziometacarpal Arthrosis Symptoms and Disability (TASD)—into Brazilian Portuguese. This questionnaire helps patients describe their symptoms and how much those symptoms affect their daily life. For example, it can show how thumb arthritis impacts your ability to write, cook, or even grab your keys.
Steps to translate TASD:
- The team translated the original questionnaire into Portuguese.
- They did a reverse translation into English to make sure it matched the original meaning.
- Experts reviewed both translations to finalize the Brazilian Portuguese version, called TASD-BR.
What did this study find?
Here’s where it gets exciting. After translating the questionnaire, the researchers tested TASD-BR on people with thumb arthritis to ensure it works well in Portuguese. Thirty-one patients used it to describe their symptoms and struggles.
So what did they find?
- High accuracy: The questionnaire’s internal consistency got a score of 0.927 in Cronbach’s alpha testing. That’s excellent! Internal consistency simply means that all the questions are working well together to measure what they’re supposed to.
- Good reliability: The researchers also checked something called reliability—it’s all about getting consistent results every time somebody uses the questionnaire. They measured this using the Intraclass Correlation Coefficient (ICC). TASD-BR scored very high, with a kappa value of 0.961.
- No extremes: The study confirmed there weren’t any ceiling or floor effects. This means the questions in the TASD-BR aren’t so hard or so easy that they fail to capture real differences in how people feel.
Why is this important for you?
With TASD-BR, your doctors can better understand the intensity of your symptoms and how much thumb arthritis is affecting your life. This tool can help you and your doctor decide whether a treatment is really working and track your progress.
