De Quervain’s Tenosynovitis: Then and Now

In 1895, Swiss surgeon Fritz de Quervain identified a common musculoskeletal disorder among manual labourers, particularly women working in laundries. It was popularly referred to as Washerwoman’s Sprain. At the time, the condition was caused by repetitive wringing of heavy, wet clothes and the forceful gripping of irons for hours at a stretch.

Fast forward to today, and this same disorder is more prevalent than ever. The wringing has been replaced by relentless scrolling, clicking, and typing by the modern Display Screen Equipment (DSE) user. What was once an occupational injury of the industrial age has now become a problem of the digital workspace.

What Is De Quervain’s Tenosynovitis?

De Quervain’s tenosynovitis is a repetitive strain injury that causes pain on the thumb side of the wrist. It affects two tendons that run through a narrow tunnel, known as a sheath, at the base of the thumb. When these tendons are overused, the sheath becomes inflamed and thickened, making smooth movement difficult and painful. For remote workers and DSE users, this often presents as thumb-side wrist pain when opening jars, gripping objects, or performing simple daily tasks. Most commonly, pain is noticed during smartphone use, laptop work, or prolonged touchpad navigation. What begins as mild discomfort can progress into persistent wrist pain that interferes with productivity.

Why Are Remote Workers More Prone to De Quervain’s Tenosynovitis?

While traditional office workers may have access to ergonomic keyboards and mice, many remote workers fall into what can be described as the laptop trap. Improvised workstations and prolonged screen time place the wrist and thumb under repeated stress. Common contributing factors include:

1. Static loading: Holding a smartphone for long periods or hovering the thumb over a trackpad creates constant tension in the thumb tendons.

2. Repetitive spacebar striking: It is often overlooked, but the thumb is responsible for every space between every word typed.

3. The pincher grip: Touchpad use requires repeated pinching motions that place direct stress on the radial side of the wrist.

In January 2021, a study published in the Foundation University Journal of Rehabilitation Sciences examined the frequency of De Quervain’s syndrome among mobile phone users. The study concluded that mobile users are at a higher risk of developing De Quervain’s tenosynovitis due to repetitive thumb movements during texting and gaming, especially when rest breaks are limited.

How to Diagnose De Quervain’s: The Finkelstein Test

Historically, the Finkelstein test was used to assess tendon thickening caused by repetitive manual labour. Swelling and a creaking sensation, known as crepitus, suggested restricted tendon movement. A positive test often meant the worker needed immediate rest to prevent prolonged disability.

Today, a modified version of the Finkelstein test can help identify wrist pain related to De Quervain’s tenosynovitis:

1. Make a fist with your thumb tucked inside your fingers.

2. Gently bend your wrist downward toward your little finger, as if pouring water from a jug.

3. Observe for pain along the thumb side of the wrist. A sharp, localised pain suggests a positive result

Please note: If this movement causes significant pain, it indicates tendon inflammation and should be assessed by a physiotherapist.

Physiotherapy Management and Ergonomic Tips for Recovery

The good news is that De Quervain’s tenosynovitis is highly treatable without surgery when identified early. Physiotherapy and ergonomic adjustments play a key role in recovery.

Helpful strategies include:

1. The 20–20–20 rule for hands: We know it for eyes, but hands need it too. Every 20 minutes, stop typing and gently stretch your thumbs for 20 seconds.

2. Switching to a vertical mouse: Standard mice encourage wrist pronation. A vertical mouse promotes a neutral wrist position and reduces pressure on the thumb tendons.

3. Ice therapy: Applying ice to the base of the thumb for 10 to 15 minutes after prolonged computer use helps reduce inflammation.

4. Thumb-to-palm stretch: Open the hand flat and gently move the thumb across the palm toward the base of the little finger. Hold for five seconds and repeat.

5. Voice-to-text tools: Dictation software reduces repetitive thumb use and allows functional rest during long work tasks.

The tools we use have evolved from heavy irons to lightweight smartphones, but human anatomy has not changed. For remote workers, desk setup and daily work habits are often the strongest predictors of long-term musculoskeletal health.

Do not allow a Victorian-era injury to disrupt a 21st-century career. Persistent thumb or wrist pain is not something to ignore. A physiotherapist can assess your workstation, guide targeted exercises, and help you return to pain-free productivity.
