De Quervain’s tenosynovitis occurs when the tendons at the base of the thumb become irritated as they pass through a narrow tunnel at the wrist. This can cause pain, swelling or aching along the thumb side of the wrist, often made worse by gripping, pinching or repetitive thumb movements.

At work, everyday tasks such as mouse use, scrolling, texting or typing can quietly increase strain on these tendons. Understanding how work habits influence symptoms helps reduce irritation and support steadier comfort throughout the day.

How De Quervain’s tenosynovitis affects comfort at work

When the thumb tendons are inflamed, they become sensitive to both repetition and awkward positioning.

Common workplace contributors include:

• Repetitive thumb use
Frequent clicking, scrolling, texting or trackpad use increases load through the thumb tendons.

• Sustained wrist deviation
Using the mouse or keyboard with the wrist angled towards the thumb side increases tendon friction.

• Pinching or gripping
Holding devices, pens or phones tightly places extra strain on the thumb base.

• Working with unsupported hands or forearms
Hovering the hands increases muscular effort and tendon load.

These factors often lead to increasing pain or stiffness as the working day goes on.

How to reduce strain and support thumb and wrist comfort

De Quervain’s tenosynovitis often responds well to reducing thumb load, improving wrist position, and using gentle, comfortable movement.

1. Reduce repetitive thumb use

Limit prolonged scrolling, clicking or texting where possible.
Use keyboard shortcuts or voice input to reduce reliance on the thumb.

2. Keep the wrist in a neutral position

Adjust keyboard and mouse height so the wrist stays relatively straight rather than angled towards the thumb side.
Avoid resting the wrist on hard desk edges.

3. Support the forearm

Resting part of the forearm on the desk or armrest reduces strain through the wrist and thumb.
This allows the hand to move with less effort.

4. Use gentle, pain-free movement

Light movement helps reduce stiffness without aggravating the tendons, such as:

• Thumb opening and closing within comfort
• Wrist circles performed slowly
• Changing hand position regularly

Movements should feel easy and stop short of pain.

5. Break up repetitive tasks

Change hand position or take brief posture breaks every 20–30 minutes.
Short, frequent breaks are often more effective than longer, infrequent rests.

Final thoughts

De Quervain’s tenosynovitis is often driven by repeated, low-level thumb and wrist strain rather than one single activity. By reducing repetitive thumb use, improving wrist positioning and supporting the forearm, many people can significantly improve comfort during the working day. Small, practical adjustments often make a meaningful difference.
