De Quervain's tenosynovitis
Here is a clear, concise overview of De Quervain’s Tenosynovitis:
De Quervain’s Tenosynovitis (Overview)
It is an inflammation of the tendons on the thumb side of the wrist, specifically the Abductor Pollicis Longus (APL) and Extensor Pollicis Brevis (EPB) tendons within the first dorsal compartment.
Causes
Repetitive thumb or wrist movements
Lifting heavy objects with thumb extended
Holding babies (“mother’s thumb”)
Overuse (texting, typing, gripping)
Trauma or direct injury
Inflammatory conditions (rarely)
Symptoms
Pain on the thumb side of the wrist
Pain worsens with gripping, lifting, twisting
Swelling near the radial styloid
Difficulty moving thumb
A catching or snapping sensation
Tenderness on the radial wrist
Special Test
Finkelstein Test
Patient makes a fist with thumb inside the fingers
Therapist ulnar deviates the wrist
Sharp pain over the radial styloid = positive
Physiotherapy Treatment
1. Acute Phase
Rest and activity modification
Thumb-spica splint
Ice 10–15 minutes
NSAIDs (if advised by doctor)
2. Manual Therapy
Soft tissue mobilization over APL & EPB
Myofascial release
Joint mobilization of wrist and thumb
3. Exercises
Stretching
Wrist ulnar deviation stretch
Thumb flexion stretch
APL/EPB tendon gliding
Strengthening
Isometric thumb extension
Wrist radial/ulnar deviation strengthening
Grip strengthening (light)
4. Modalities
Ultrasound therapy
TENS for pain relief
Laser therapy (if available)
5. Ergonomics
Avoid repetitive thumb strain
Modify lifting techniques
Use a supportive splint during activities
When to See a Doctor
If pain persists >2–4 weeks
Severe swelling
Suspected tendon rupture
Failure to improve with physiotherapy
May require corticosteroid injection or, rarely, surgery
