De Quervain's Tenosynovitis

Managing De Quervain's Tenosynovitis at the Computer: Ergonomic Tips and Tools

De Quervain's Tenosynovitis is a repetitive strain injury (RSI) affecting the tendons on the thumb side of the wrist, often causing pain when gripping, moving the wrist, or even making a fist. This guide explains the causes and symptoms of De Quervain's Tenosynovitis and offers ergonomic solutions for managing symptoms at your workstation.

What is De Quervain's Tenosynovitis?

De Quervain's Tenosynovitis is a painful condition caused by inflammation of the tendons that run along the thumb side of the wrist. If left untreated, the pain can extend from the thumb down to the forearm, making simple tasks like gripping or pinching difficult.

Symptoms

  • Pain and swelling at the base of the thumb
  • Difficulty moving the thumb and wrist, particularly when gripping or pinching
  • Pain that may extend down into the forearm

Causes of De Quervain's Tenosynovitis

This condition is often due to repetitive wrist motions, such as those used when handling a computer mouse. Each time you grip, pinch, or make a fist, two tendons in the thumb and wrist slide through a small tunnel. With frequent use, the sheath around these tendons can become irritated, leading to swelling and limited thumb movement.

Treatment for De Quervain's Tenosynovitis

The goal of treatment is to reduce inflammation and allow the tendons to rest. A physiotherapist may suggest a combination of anti-inflammatory treatments and supportive measures, such as:

  • Immobilisation: Using a splint or brace to limit wrist and thumb movement and allow the tendons to heal.
  • Anti-inflammatory Medication: Medication or topical treatments to reduce swelling and relieve pain.

Ergonomic Equipment for De Quervain's Tenosynovitis

If you experience discomfort using a computer mouse, consider switching to an ergonomic mouse to reduce the strain on your thumb. Ergonomic mice are designed to promote a neutral wrist posture and decrease the gripping force required.
