The Hand Therapy Blog

Carpal Tunnel Syndrome (CTS) affects thousands of people across Northern Ireland, particularly those who spend hours typing, using a mouse, or performing repetitive hand movements. At Hand Therapy Services NI, we treat carpal tunnel syndrome regularly. Office based workers often tell us about their job requiring alot of computer or desk based activity. They ask for advice regarding work related activities and how they can take action to reduce the pain, numbness and tingling related to typing, repetitive movements or continued gripping at work.

How Workstation Ergonomics Affect Carpal Tunnel Syndrome

Carpal Tunnel Syndrome develops when the median nerve is compressed at the wrist. In the workplace, this compression is often increased by repetitive tasks, sustained gripping, or prolonged wrist bending. Poor desk setup and posture can aggravate symptoms. For a full overview of causes and symptoms, visit our Carpal Tunnel Syndrome blog, where we explain how nerve compression impacts hand function.

Keyboard and Mouse Ergonomics at Work

For those who work at a desk or computer, one of the most common questions we get asked is “what is the best keyboard and mouse to use with carpal tunnel syndrome.” We advise that your keyboard should be positioned at elbow height, allowing your forearms to rest comfortably with wrists kept in a neutral, straight position. Avoid bending the wrists upwards or resting them on hard desk edges. Your mouse should sit close to the keyboard to reduce overreaching. Many people in office jobs across Belfast and Northern Ireland benefit from alternative mouse designs, such as vertical mice, which reduce prolonged wrist strain.

Desk, Chair, and Sitting Position

People frequently ask “can desk height worsen carpal tunnel syndrome symptoms?” The answer is yes. A desk that is too high forces wrist extension, while a desk that is too low encourages wrist flexion, both increase pressure on the median nerve, which can worsen your symptoms.

Your chair should allow: • Feet flat on the floor • Hips slightly higher than knees • Back and arm support to reduce shoulder tension

Poor sitting posture increases strain through the shoulders and arms, which can contribute to wrist and hand symptoms over time.

Screen Height and Upper Limb Posture

Although carpal tunnel syndrome affects the wrist and hand, posture of the neck and shoulders plays a major role. The nerve originates at your neck, crosses the shoulder and runs along your arm. Tensioning the nerve at the neck or shoulders can have an impact on its ability to work and function at wrist level and a screen positioned too low or too high can lead to compensatory postures at the neck or shoulders causing nerve tension throughout the arm.

Your monitor should be positioned so the top of the screen is roughly at eye level. This encourages neutral posture and reduces load through the wrists during prolonged desk work, a key factor for people working full-time desk based roles.

Workplace Ergonomics Checklist for Carpal Tunnel Syndrome

Below is a workplace ergonomics checklist you can follow to help ease symptoms. ✅ Desk and Chair • Desk at elbow height when seated • Chair supports lower back • Feet flat on floor or footrest

✅ Keyboard and Mouse • Keyboard directly in front of you • Mouse close to keyboard • Wrists kept straight and relaxed • Avoid resting wrists on hard surfaces

✅ Screen and Posture • Screen at eye level • Shoulders relaxed, not elevated • Head positioned over shoulders

✅ Work Habits • Change position every 30–45 minutes • Take short movement breaks • Vary tasks throughout the day

✅ Symptom Awareness • Monitor night-time numbness • Notice grip weakness or clumsiness • Seek early advice if symptoms persist

When Ergonomic Changes Are Not Enough

Ergonomic solutions are most effective in the early stages of carpal tunnel syndrome. If symptoms continue despite workplace changes, this may indicate ongoing nerve compression requiring specialist input.

Warning signs include: • Constant numbness • Increasing night pain/ interrupted sleep • Reduced grip strength/ dropping items

If you are based in Northern Ireland and experiencing these symptoms, early assessment can help prevent long-term nerve damage or the need for more invasive treatments such as injections or even surgery. If you need specialist, expert help to manage your carpal tunnel symptoms, contact us to arrange a hand therapy assessment and treatment in our Belfast, Hillsborough or Newry clinics.

Final Thoughts

Workplace ergonomics are a powerful tool in managing carpal tunnel syndrome symptoms.
