For De Quervain’s, the splint and the load change do most of the work, and the exercises support them. That ordering matters, because people usually do the reverse — they stretch an already irritated tendon several times a day and wonder why the thumb side of the wrist keeps flaring.
Two tendons that pull the thumb out and back run through a narrow tunnel at the wrist. The tunnel or the tendons have swollen and they no longer glide freely. Anything that repeatedly forces the thumb through that tunnel under load keeps the irritation alive.
First, the two things that matter more than exercises
- A thumb spica splint. It must include the thumb up to but not past the tip joint. A plain wrist brace does nothing here, and this is the single most common mistake with this condition. Worn at night, and during the specific aggravating tasks, for four to six weeks
- Changing how you lift. The classic aggravator is lifting with the thumb up and the wrist bending towards the little finger — a kettle, a pan, a baby under the arms. Switch to two hands, scoop from underneath, keep the wrist straight. New parents: lift with forearms rather than thumbs
Phones matter too. Thumb-typing on a large handset held one-handed is the modern version of the same load.
The exercises, in the right order
Early, while it is irritable:
- Gentle thumb tendon gliding. Thumb out to the side, then across the palm to the base of the little finger, slowly, within comfort. Ten repetitions, three times a day. Movement to keep the tendons gliding, not stretching
- Wrist movements with the thumb relaxed. Up and down, side to side, no load
From about week three to four, once the sharp pain has settled:
- Isometric thumb abduction. Thumb pressed gently outwards against the fingers of the other hand, no movement. Hold ten seconds, five repetitions
- Radial deviation with a light weight. Forearm on a table, thumb up, small weight in the hand, lift the hand slowly upwards and lower it over three seconds. Two sets of ten
- Grip and pinch work, last of all, once the above is comfortable
The Finkelstein position — thumb in the fist, wrist bent towards the little finger — is a test, not a stretch. Doing it repeatedly because it reproduces the pain is doing the injury over and over.
What not to do
- Aggressive thumb stretching. An irritated tendon in a tight tunnel does not want end-range stretch
- Testing it repeatedly to see if it still hurts. It will, and each test sets you back
- Wearing the splint all day for months. Four to six weeks of targeted use, then wean. Longer than that costs thumb strength and wrist range
- Stopping the splint the day it feels better. The tendon settles before it recovers
When it is not going to settle this way
Six weeks of a correctly fitting spica, real load change, and the exercises above is a fair trial.
If there has been no meaningful improvement, a corticosteroid injection into the sheath is the usual next step and works well in this condition. Surgery to release the tunnel exists for the small number who do not respond.
Worth ruling out first: pain a hand’s width higher up the forearm, sometimes with a squeak you can feel, is intersection syndrome, which gets treated as De Quervain’s constantly.
Pain lower down, in the hollow at the base of the thumb after a fall, is a scaphoid until imaging says otherwise. And grinding at the joint itself when opening jars is thumb base arthritis, a different problem with a different splint.
The full picture of the condition is in De Quervain’s tenosynovitis, and which splint and how long covers the wear schedule.
Rest the tunnel, change the lift, then load it. In that order.
