Ergonomic Considerations

What is a Trigger Finger?

Trigger finger is a painful condition that 'locks' or 'catches' the thumb or a finger when bended. It can affect one or more fingers or thumb, and on either or both hands.  It is known also as stenosing tenosynovitis. 


Symptoms include; clicking, popping or snapping when you straighten or bend your fingers and/or thumb, stiffness, pain at the base of the affected finger or thumb, and a locked finger or thumb that you are unable to straighten.

What Causes Trigger Finger? 

Trigger finger/thumb can be caused by a number of situations, but the most common is a repeated or forceful use of your fingers and thumb.  The tendon at the base of the finger or thumb usually glides easily through the tissue that covers it (called a sheath) thanks to the synovium, a membrane that surrounds joints and keeps them lubricated. Sometimes, a tendon gets inflamed and swollen. Long-term irritation of the tendon sheath can lead to scarring and thickening that affect the tendon's motion. When this happens, bending your finger or thumb pulls the inflamed tendon through a narrowed sheath and makes it snap or pop (Nazario, 2020).

How is Trigger Finger Treated?

The treatment of trigger finger usually depends on the severity of the symptoms.  Rest, splinting, stretching and certain medications are generally advised by health professionals.  Surgery may also be required if it is severe - this will all be recommended by your health specialist.  It is also important to look at the way you complete your daily activities to understand what may have aggravated the condition, and how you can change the way you do tasks to ease the pain.

Trigger finger can become severe, so looking into what aggravates the condition, then ceases these activities or changing the way you perform tasks can help relieve the pain.

What Ergonomic Equipment is Recommended for Trigger Finger? 

It is important to consider your working environment when looking at treating Trigger Finger. Once you have consulted with your GP and a Physiotherapist/Occupational Therapist, and your symptoms are beginning to improve, you may want to try to re-introduce using a computer mouse and keyboard again. Remember to start slowly and gradually increase the amount of time you use your mouse and keyboard.

If you find your computer mouse aggravates your symptoms, you may need to consider changing to an ergonomic mouse.

Ergonomic mice, place your wrist and forearms in a more natural posture that helps to reduce the amount of muscle activity required to use your mouse. This in turn will help to reduce your symptoms and also the risk of aggravating your symptoms while you recover. 


We recommend the Ergofeel vertical ergonomic mouse, or the Ease vertical ergonomic mouse (depending on your hand size) as their shape keeps your fingers and thumb in a relaxed, straightened position and allow your fingers and thumb a chance to heal from the condition.  These particular mice will also place your hand and arm in a more natural posture which will help to reduce the tension in your forearm muscles and tendons. By switching to this mouse, you will feel the difference immediately. 


The Ergofeel and Ease vertical ergonomic mouse are some of our most popular selling ergonomic mice, and have helped many individuals with trigger finger to recover completely and continue their work on a computer.
