Thumb arthritis physical therapy in Carmel, Indiana

Opening a jar, turning a key or pinching hard puts large forces through the small joint at the base of the thumb. When the cartilage in that joint is thinning, those forces cause pain, and the ligaments that hold the joint steady may loosen, letting the joint shift slightly under load.

The CMC joint is shaped like a saddle, which lets the thumb move in many directions and makes it so useful. That same mobility makes it one of the most common places in the hand for osteoarthritis. It is seen more often in women and after middle age, and it can follow an old injury to the thumb.

Over time some people notice a bump at the base of the thumb, and the thumb can start to sit closer to the palm, making it hard to open the hand wide around a large object. These changes happen gradually, and they do not always match how much it hurts.

Pain often comes in waves. A week of heavy gardening, a pickleball tournament, holiday cooking, or a long stretch of texting and gaming on a phone can bring on a flare that lasts days to weeks, followed by calmer spells. Knowing your own triggers is one of the most useful things a first visit can help you work out.

A thumb splint that supports the base of the thumb, either a soft neoprene sleeve or a rigid custom-molded one, reduces pain for many people, especially during heavier tasks or at night. Your therapist will help you choose a type and decide when to wear it so the thumb does not stiffen.

Exercises focus on the muscles that stabilize the joint. The first dorsal interosseous, the muscle in the web between the thumb and index finger, and the thenar muscles at the base of the thumb help hold the joint in a stable position when you pinch. Strengthening them in a good position, often with putty, bands or light pinch grips, can reduce pain over time.

Joint protection is the third piece: using larger handles, jar openers, key turners and both hands for heavier jobs, and pinching with the thumb rounded rather than collapsed. These small changes add up across a day of cooking, typing, gardening or playing pickleball.

Strength beyond the thumb matters as well. A stronger forearm and shoulder let you carry and lift with larger muscles, so the thumb is not the weak link. In a private suite your therapist can practice real tasks with you, such as carrying a weighted bag with an open hand, holding a racket with the thumb in a protected position, or lifting a pan with two hands, and check that the technique holds up when you are tired.

• Soft or custom thumb splint for heavy tasks and nights
• Web-space and thumb-base strengthening with putty or bands
• Pinch practice with a rounded, stable thumb position
• Built-up handles, jar and key aids, two-handed lifting
• Heat before activity for stiffness; ice after for soreness

Swap pinch for grip where you can: hold a mug by its body rather than its handle, use a wide pen, and open jars with a rubber grip or an opener. Spread loads across both hands and keep the thumb rounded, not bent backward, when you press or pinch.

Pickleball and tennis players often do better with a slightly larger grip and an overgrip, and golfers may try thicker grips. Gardeners can use ratchet pruners and padded gloves. If you lift weights, neutral-grip handles and lifting straps take strain off the base of the thumb.

If your thumb is stopping you doing things you value, the two-minute questionnaire tells the matching team what you want back, and they will talk through whether a therapist in the network or a certified hand therapist is the right next step.
