Wrist tendinitis and tenosynovitis occur when the tendons, or the tendon sheaths that allow them to glide smoothly, become irritated through repeated use or sustained load. This can lead to pain, stiffness, swelling or a “catching” sensation in the wrist or hand, often made worse by typing, mouse use or gripping.
At work, small habits around wrist position, repetition and support can quietly increase strain on these tissues. Understanding these patterns helps reduce irritation and support steadier comfort through the day.
When wrist tendons are irritated, they are sensitive to both repetition and awkward positioning.
Common workplace contributors include:
• Sustained wrist bending
Typing or mouse use with the wrist held in extension or flexion increases friction through the tendon sheaths.
• Repetitive hand and finger movements
Constant clicking, scrolling or typing increases cumulative tendon load.
• Working with unsupported wrists or forearms
Hovering the hands increases muscular effort and tendon strain.
• Excessive gripping
Holding the mouse, pen or phone tightly increases tension through the wrist tendons.
These factors often lead to increasing soreness, stiffness or swelling as the working day goes on.
Wrist tendinitis and tenosynovitis often respond well to reduced repetition, neutral wrist positioning, and gentle, comfortable movement.
1. Keep the wrist as neutral as possible
Adjust the keyboard and mouse so the wrist stays relatively straight rather than bent up or down.
Avoid resting the wrist on hard desk edges that increase pressure.
2. Support the forearm, not the wrist
Resting part of the forearm on the desk or armrest reduces load through the wrist tendons.
This allows the hand to move with less strain.
3. Reduce gripping effort
Choose a mouse that fits comfortably and doesn’t require constant squeezing.
Use a light touch when typing or holding devices.
4. Use gentle, pain-free movement
Light movement helps reduce stiffness and improve tendon glide, such as:
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.
Wrist tendinitis and tenosynovitis are often driven by small, repeated stresses rather than one single movement. By improving wrist position, supporting the forearm and reducing repetitive strain, many people can significantly improve comfort and prevent symptoms from escalating during the working day.
