What De Quervain's Tenosynovitis Is
De Quervain's is irritation of the two tendons on the thumb side of your wrist, where they run through a tunnel at the base of the thumb. It causes pain with thumb and wrist movements — gripping, pinching, lifting, wringing, and especially thumb-out motions — and is common with repetitive thumb use (and in new parents lifting babies). Offloading the thumb and progressively loading the tendons settles it.
- Primary — Thumb-side wrist tendinopathy — pain at the base of the thumb and wrist with gripping, pinching, and thumb movements. Most common, and this protocol is for it.
- Secondary — Arthritis or nerve involvement — pain deeper in the thumb joint, or numbness and tingling, may be thumb-base arthritis or a nerve issue and needs assessment.
Involved tissues: The two thumb tendons (APL and EPB) and their sheath on the thumb side of the wrist, where repetitive load makes them swollen and irritated.
Two pillars for De Quervain's: first, offload and calm the thumb — a thumb-and-wrist splint, and modifying the repetitive thumb-out and gripping tasks; second, progressively restore mobility and load the tendons — gentle gliding first, then progressive thumb and wrist strengthening. Rest the thumb, then rebuild it.
Offload the thumb, then load it
De Quervain's is a load problem in two small thumb tendons — they got more repetitive thumb-and-wrist work than they could handle (classically lifting a baby with thumbs-out, or repetitive phone and tool use). So the early game is offloading: a thumb-spica splint that rests the thumb and wrist, plus modifying the specific task. Once it calms, you progressively restore mobility and load the tendons with graded thumb and wrist strengthening, so they can handle your demands again. Rest it enough to calm down, then load it enough to last.
⚠️ Screen Before You Start — Get Assessed First If You Have:
- ●Numbness or tingling in the thumb or hand
- ●Significant swelling, redness, and warmth with fever
- ●Pain deep in the thumb joint with grinding (possible thumb-base arthritis)
- ●Pain after a fall onto the wrist or thumb (rule out a fracture)
- ●Loss of thumb movement or strength that isn't improving
This is education, not a diagnosis, and doesn't replace hands-on care.
🌡️ Finding your stage
Take your movement temperature. Pain with light thumb/wrist use or at rest = Protection. Pain only with firmer gripping or pinching = Controlled Motion. Pain only with heavy or repetitive demand = Return to Function. Brief loading discomfort that settles is fine; a lasting flare means back off. Re-check every session.
Phase 1 · Acute
Protection Phase
🌡️ Pain with light thumb/wrist use or at rest
Goal: Calm and offload the thumb with a splint and task modification, and start gentle gliding.
Manual treatment: Pain-relief modalities and gentle, symptom-free motion.
Frequency: Daily · gentle sessions.
A. Calm & Offload
SoftWave Therapy
Video coming soon- Dose
- As scheduled
- How
- Applied to the thumb-side wrist tendons to calm symptoms and stimulate healing.
- Watch for
- The anchor of the early phase.
Thumb-Spica Splint
Video coming soon- Dose
- As needed
- How
- A splint that rests the thumb and wrist together, offloading the irritated tendons.
- Watch for
- One of the biggest early wins — rest the thumb so the tendons calm.
Activity Modification
Video coming soon- Dose
- Ongoing
- How
- Change how you lift (e.g., lift from underneath, not thumbs-out) and cut back the repetitive thumb-out and gripping tasks.
- Watch for
- Find and modify the specific repetitive thumb task driving it.
B. Gentle Motion
Pain-Free Thumb & Wrist Motion + Tendon Glides
Video coming soon- Dose
- 1–2 × 5–10 gentle
- How
- Move the thumb and wrist gently through a comfortable range, avoiding the provocative thumb-out, wrist-down position.
- Watch for
- Gentle — should not reproduce the pain. Avoid the provocative position early.
Offload the thumb — a splint and modifying the repetitive task are the biggest early wins. Avoid the provocative thumb-out, wrist-bent-down position that reproduces it.
✅ Ready for the next phase when:
Pain with daily thumb use is settling.
Tracking Your Progress
The weekly stability check: am I better, the same, or worse than last week?
Better
Stay the course; progress load as pain shrinks to only heavy/repetitive demand.
Same
Change the load or drill; re-check you've offloaded the thumb-out task.
Worse
Drop back a phase and re-splint. If numbness or deep joint pain appears, get assessed.
The Rules That Govern This Protocol
- 1Offload the thumb — a splint and task modification are the biggest early wins.
- 2Load the tendons progressively once calm — mobility, then strengthening.
- 3Fix the aggravating technique (e.g., how you lift) so it doesn't return.
- 4No lasting increase in pain after a session (brief settling discomfort is okay).
