If you have pain at the base of your thumb, you are not alone. This pain often comes from a condition called rhizarthrosis. Many people wonder if there is a better way to treat it without surgery.
A new study from 2024 shows a fresh approach that combines gentle hand movements with a special exercise for your thumb. The goal is to make your thumb stronger, reduce pain, and help you use your hand better.
Here are three important things this study found:
- Gentle manual therapy can help improve thumb joint movement and reduce pain.
- A specific exercise using a rubber band strengthens an important muscle without putting stress on your sore thumb joint.
- This method is designed for people with mild to moderate thumb arthritis.
Key Findings at a Glance
- Research shows that rhizarthrosis affects the first joint of the thumb and leads to pain and trouble using your hand.
- According to this study, conservative treatment is best for mild to moderate cases, known as Eaton-Littler grades I and II.
- The new method combines three phases of manual therapy with a targeted rubber band exercise.
- Studies indicate that strengthening the first dorsal interosseous muscle can reduce stress on the thumb joint.
- Patients start with 5 to 10 repetitions or 5 seconds of muscle squeeze and slowly increase over time.
What Is Rhizarthrosis?
Rhizarthrosis is also called thumb arthritis. It is very common. It makes everyday tasks like opening jars or turning keys hard and painful.
Many people first feel pain when they pinch or grip something. The joint can also feel stiff. Sometimes it looks a little swollen.
You may be wondering why this matters. When this joint stops working well, your whole hand is affected. That is why finding good treatments is so important.
How Does This New Treatment Work?
Research shows that this new approach combines two main parts. The first part is called manual therapy. The second part is a specific exercise program.
Manual therapy means a therapist uses their hands to gently move your thumb joint. This can help reduce pain and improve how your thumb moves.
The exercise part focuses on making one muscle stronger. This muscle helps spread your fingers apart. When it is stronger, it can take pressure off your sore thumb joint.
According to this study, the method is based on a careful look at how the thumb joint works. That means the treatment targets the real problem.
What Is the Manual Therapy Part?
The manual therapy has three phases. Each phase has a different goal.
Phase One: Gentle Pulling
In the first phase, the therapist gently pulls on your thumb. This is called joint distraction. It helps create space in the joint. This can make the pain less and help your thumb move more freely.
Here is where it gets interesting. This gentle pulling does not force your thumb. It just eases the pressure inside the joint.
Phase Two: Active Thumb Movement
In the second phase, your thumb starts to move. The therapist asks you to squeeze your thumb toward your hand. This is called isometric adduction. That means you tighten your thumb muscles without actually moving the thumb much.
After that, the therapist helps you move your thumb away from your hand. This is called assisted abduction. Studies indicate that the movement between pulling your thumb toward your hand and pushing it away is the first movement to become limited in rhizarthrosis.
Phase Three: Movement With Mobilization
The third phase uses something called Mulligan’s Mobilization With Movement. This is a technique where the therapist gently moves your joint while you move your fingers at the same time.
The idea is that moving your joint and your fingers together can give extra help. It is always done without pain. If it hurts, the therapist stops or adjusts.
Let us look closer. These three phases work together to help your thumb feel better and move more smoothly.
What About the Exercises?
According to this study, the exercise part is just as important as the manual therapy. The exercise targets a muscle called the first dorsal interosseous.
The exercise is simple. You place a rubber band around your thumb and your pinky finger. Then you spread your fingers apart against the band. This makes the first dorsal interosseous muscle work.
The beauty of this exercise is that it does not move your sore thumb joint. It strengthens the muscle without adding stress to the painful area.
How Do You Start?
Research shows that you should start slowly. Here is what the study recommends:
- Begin with 5 to 10 repetitions of spreading your fingers.
- Or hold the muscle squeeze for 5 seconds without moving. This is called an isometric contraction.
- Repeat this exercise several times during the day.
How Do You Progress?
As you get stronger, you can make the exercise harder. Here is how:
- Add an extra turn to the rubber band to make it tighter.
- Use a thicker or stronger rubber band.
- Increase the number of repetitions up to 15.
- Hold the muscle squeeze longer, up to 10 or 15 seconds.
This slow and steady approach helps your muscle get stronger safely. It gives your body time to adapt.
Why Is This Approach Different?
Most exercises for thumb arthritis are general. They are not made specifically for rhizarthrosis. This new method is different because it is based on the science of how the thumb joint works.
According to this study, the problem is that many older treatments do not have strong research to prove they work. There are not many studies that compare different methods.
This new approach tries to fix that. It gives a clear plan based on biomechanics. That means it looks at the forces and movements in your thumb joint.
The authors say more research is needed. They want to test this method in clinical trials. Clinical trials are studies where patients try the treatment and doctors measure the results.
But the ideas behind this method are promising. They make sense based on what we know about the thumb joint.
Who Can Benefit From This Treatment?
Research shows that this treatment is designed for people with mild to moderate rhizarthrosis. In medical terms, these are called Eaton-Littler grades I and II.
If your thumb pain is not too severe, this kind of conservative treatment may help you. Conservative treatment means trying things like exercises and therapy before considering surgery.
If you have severe thumb arthritis, your doctor may suggest other options. But for many people, this approach could make a real difference.
Frequently Asked Questions
How long does it take to see results?
The study does not give a specific timeline. Results depend on each person. Some people may feel better after a few weeks. Others may take longer. Consistency is important. Doing the exercises every day and working with a therapist can help.
Can I do the rubber band exercise at home?
Yes. According to this study, the exercise is designed to be done at home. You only need a simple rubber band. Start slowly. If you have questions, ask your therapist to show you the correct way.
Is manual therapy painful?
No. Research shows that the manual therapy should always be done without pain. If something hurts, the therapist will stop or change the movement. The goal is to help, not to cause more discomfort.
Do I need surgery if I have rhizarthrosis?
Not always. Studies indicate that conservative treatments like this one are preferred for mild to moderate cases. Surgery is usually considered only if other treatments do not help or if your arthritis is very severe. Talk to your doctor about what is best for you.
Conclusion
Thumb pain from rhizarthrosis can make life difficult. But this new approach offers hope. It combines gentle manual therapy with a smart exercise that strengthens your hand without stressing your sore joint.
Research shows that this method is based on the science of how your thumb works. It is designed for people with mild to moderate thumb arthritis.
If you have thumb pain, talk to your doctor or therapist. Ask if this approach might be right for you. Starting early with the right treatment can make a big difference.
Remember, healing takes time. Be patient with yourself. Small steps can lead to big improvements.
