If you have thumb pain or rhizarthrosis, you’ve come to the right place. Today, we’re talking about a fascinating study that shows how imagining hand movements (even without moving!) can help reduce pain and improve recovery after hand surgery. Sounds interesting, right?
The key points from the study are:
- Imagining moving your hand helps counteract the problems caused by keeping it still after surgery.
- The more often people used motor imagery (thinking about moving), the faster their recovery and the less pain they felt.
- The study used brain imaging to show how this exercise changes the brain in a helpful way.

How does imagining movements help?
Most of us think we’ll lose strength if we stay still too long after an injury or surgery. That can happen, but here’s something you might not know—your brain plays a big role in recovery too. When you don’t use part of your body, your brain sort of ‘forgets’ how to control it. But research shows that if you imagine moving that part of your body—even without actually moving—you might be able to keep your brain active and ready to help you recover.
Motor imagery training, or M.I., is the process of mentally imagining movements. Think of it as daydreaming, but about actions like moving your hand or finger instead of random thoughts. So, even if you can’t move your thumb after surgery because it’s immobilized, mentally picturing its movement can still make a difference.
What did the study show?
This study looked at 22 people who had rhizarthrosis, which is a disease that makes moving your thumb hard and painful. The thumb is the finger you use to grab things and touch other fingers. Since rhizarthrosis is caused by wear and tear in the joint, surgery often becomes necessary.
After their surgery, everyone in the study had their thumb immobilized, meaning their thumb had to stay still and couldn’t move for a while. During this time, they were asked to do motor imagery training, where they practiced imagining moving their thumb and fingers together.
Here is where it gets interesting: some patients were really good about doing their motor imagery exercises often. On average, they stuck to the program 84% of the time—let’s call them the T+ group. Others weren’t able to follow the exercises as much—they only did it 20% of the time, and we’ll call them the T- group.
What did they find?
- The T+ group had less pain and recovered faster than the T- group.
- Their brains showed lower activity in certain areas like the premotor cortex and supplementary motor area (SMA)—these areas are responsible for planning and helping with motion.
- The brains of the T- group showed the opposite—they had extra activity in areas tied to pain like the insular cortex (a key part of the pain response system).
The result? Thinking about moving your hand may actually train your brain to recover faster and feel less pain after surgery!
Here’s a simple breakdown:
| Group | Average Compliance (%) | Outcome |
|---|---|---|
| T+ (High compliance) | 84% | Less pain, faster recovery, improved brain response |
| T- (Low compliance) | 20% | More pain, slower recovery |
Frequently Asked Questions
What is rhizarthrosis?
Rhizarthrosis is a condition where the joint at the base of your thumb becomes worn down and painful. It makes it hard to move your thumb comfortably.
How do you practice motor imagery?
Just imagine yourself moving your hand or thumb step by step. Picture each motion clearly in your mind without actually doing it.
Can imagining exercises replace physical therapy?
No, imagining movements is helpful during recovery, but it’s not a full replacement for physical therapy. Once you’re ready to move your hand, working with a therapist is still important.
How much motor imagery practice is needed?
The study found benefits in people regularly practicing, reaching roughly 84% compliance with their assigned exercises. Doing it consistently seems to make a big difference.
Conclusion
In summary, if you’re recovering from thumb surgery or experiencing issues with rhizarthrosis, motor imagery—or imagining moving your hand—might help. It supports your brain in staying active and can ease pain and accelerate recovery.
