If you have pain at the base of your thumb, you might have a condition called trapeziometacarpal osteoarthritis. That is a long word that simply means arthritis where your thumb meets your hand. This kind of thumb pain can make everyday tasks very hard. You might wonder if physical therapy or occupational therapy can really help.
A team of researchers looked at 218 studies to find out what works best. They wanted to know if therapy can reduce pain, improve how your thumb works, and make your life better. They found some very helpful answers.
Here are three important things they discovered:
- Therapy that combines different treatments works better than doing just one thing.
- Special splints can help reduce pain, and simple soft splints work just as well as hard custom made ones.
- These treatments are especially good at reducing pain.
Key Findings at a Glance
- According to this study, multimodal therapy (combining different treatments) is more effective for pain than single treatments.
- Research shows that pre-fabricated neoprene splints and custom-made thermoplastic splints reduce pain equally well.
- Physical and occupational therapy interventions are effective at treating trapeziometacarpal osteoarthritis pain.
- Single interventions alone do not seem to be effective for pain relief.
- The study found 27 reliable studies out of 218 examined.

What is thumb arthritis and why does it hurt so much?
Trapeziometacarpal osteoarthritis is arthritis at the bottom of your thumb. This is also called rhizarthrosis or CMC arthritis. CMC stands for carpometacarpal, which is the joint where your thumb bone meets a small bone in your wrist.
This type of arthritis causes more pain and more problems than other hand arthritis. Why? Because your thumb is so important. You use your thumb for almost everything you do with your hands. When it hurts, simple things like opening a jar or turning a key become very difficult.
You may be wondering why this matters. Understanding where your pain comes from helps you make better choices about treatment.
What did the researchers study?
The research team wanted to answer an important question. They wanted to know if physical therapy and occupational therapy really help people with thumb arthritis.
They searched through many medical databases. These are special libraries where doctors and scientists keep their research. They looked at studies about pain, hand function, and quality of life.
Out of 218 studies they found, only 27 were good enough to use. They chose studies that were done carefully and had reliable results. Then they put all the information together to see what works best.
Here is where it gets interesting. They did something called a meta-analysis. This means they combined the numbers from many studies to get a clearer answer. This gives us stronger evidence than just one study alone.
Do splints really help with thumb pain?
Many people with thumb arthritis wear splints. A splint is a support that holds your thumb in a comfortable position. It lets the joint rest and helps reduce pain.
The researchers compared two types of splints. One type is a pre-fabricated neoprene splint. Neoprene is a soft, stretchy material like a wetsuit. You can buy these splints ready-made at a pharmacy or online.
The other type is a custom-made thermoplastic splint. Thermoplastic is a harder plastic material. A therapist molds it to fit your hand exactly. These splints usually cost more and take more time to make.
Research shows that both types of splints work equally well for pain. The study found no real difference between them. The numbers showed a standardized mean difference of -0.01, which means they performed almost exactly the same.
| Type of Splint | Material | Pain Relief |
|---|---|---|
| Pre-fabricated neoprene | Soft and stretchy | Effective |
| Custom-made thermoplastic | Hard plastic molded to fit | Equally effective |
This is good news. It means you do not need to spend extra money on a custom splint to get pain relief. A simple soft splint works just as well.
Why does combining treatments work better?
The study found something very important about how to treat thumb arthritis. According to this research, multimodal interventions work much better than single treatments.
The numbers from the study are clear. Multimodal interventions reduced pain much more than single interventions. The standardized mean difference was -3.16. This is a large difference that matters to patients.
Let us look closer. Why does combining treatments work so well? Each treatment helps in a different way. A splint rests your joint. Exercises make the muscles around your thumb stronger. Learning new ways to do tasks protects your thumb from stress. When you put these together, you get better results.
Studies indicate that single interventions alone are not effective. This means doing just one thing, like only wearing a splint or only doing exercises, does not help enough.
What kinds of treatments might be combined?
Physical and occupational therapists use many different treatments. Here are some they might combine:
- Splinting to rest and support your thumb
- Special exercises to strengthen muscles
- Manual therapy, which means the therapist moves your joint gently
- Heat or cold treatments
- Teaching you new ways to do everyday tasks
- Education about protecting your joints
Your therapist will choose the right combination for you. Every person is different, and your treatment plan should fit your needs.
What about improving hand function and quality of life?
The researchers also looked at whether therapy improves how well your hand works. They also checked if it improves your overall quality of life.
Quality of life means how happy and comfortable you feel in your daily life. When your thumb hurts, it can affect many things. You might have trouble with work, hobbies, and taking care of yourself.
Unfortunately, the study could not find strong evidence that these therapies improve function or quality of life. This does not mean therapy does not help with these things. It means the research studies did not measure these outcomes well enough or did not show clear results.
The main finding is about pain. According to medical evidence from this systematic review, physical and occupational therapy are effective at reducing pain in people with thumb arthritis. Pain reduction itself can help you function better and feel better in your life.

Frequently Asked Questions
Should I get a custom-made splint or can I buy one at the store?
According to this research, both types work equally well for pain relief. A pre-fabricated soft neoprene splint you can buy at a pharmacy or online works just as well as an expensive custom-made hard plastic splint. You can start with a simple soft splint and see if it helps.
Is therapy alone enough to treat my thumb arthritis?
Research shows that therapy, especially when it combines different treatments, is effective at reducing pain. However, you should talk with your doctor about your complete treatment plan. Therapy works well for many people, but some may need other treatments too.
How many different treatments should I try at once?
Studies indicate that multimodal therapy, which means combining several treatments, works better than doing just one thing. Your physical or occupational therapist will create a plan that fits your needs. This might include a splint, exercises, and learning new ways to use your hand.
Will therapy help me use my hand better?
The study focused mainly on pain reduction. While it could not find strong evidence about improved function, reducing your pain often helps you use your hand more comfortably. Many people find that when pain decreases, they can do more activities.
What this means for you
If you have pain at the base of your thumb from arthritis, there is good news. Physical therapy and occupational therapy can help reduce your pain.
The most important finding is that combining different treatments works better than trying just one thing. You do not need expensive custom splints. A simple soft splint can work just as well.
Talk to your doctor about seeing a physical therapist or occupational therapist. They can create a treatment plan that combines several approaches. This gives you the best chance of reducing your pain and getting back to the activities you enjoy.
Remember, you are not alone. Many people have thumb arthritis, and research keeps finding better ways to help. Taking action now can make a real difference in how you feel.
