Osteoarthritis and Computing

Osteoarthritis (OA) is the most common type of arthritis, affecting an estimated 9 million people in the UK. Osteoarthritis was previously dubbed “wear and tear” arthritis because it was thought that the joints gradually wore out over time and was an inevitable part of ageing. However, it’s now known that osteoarthritis is more complicated than this, and that while the risk of osteoarthritis does increase as we grow older it’s by no means inevitable.

Although osteoarthritis is distinct from rheumatoid arthritis which is an auto-immune disease the two forms have similarities in the way in which they can impact quality of life, but also in the ways in which technology can support people, enabling them to maintain independence.

Given that many people with osteoarthritis can experience reduced dexterity and can find it painful to use standard keyboards and mice, AbilityNet has produced this factsheet to cover some of the options that can help make computers, laptops, tablets and smartphones easier to use.

1. What is osteoarthritis

Osteoarthritis is the most common form of arthritis in the UK. It is a long-term condition typically caused when the cartilage that protects the bones in the joins, wears down and the body is unable to repair it. This causes swelling, reduced movement, stiffness and often discomfort.

The exact cause of osteoarthritis is not known, but there are several things that are thought to contribute:

  • Age – As you grow older, your joints are subject to more wear-and-tear and our ability to repair this damage decreases.
  • Obesity – Excess bodily weight places additional stress on your joints, particularly those in the hips and knees
  • Injury – Not allowing enough time for the joint to repair itself following an injury or operation
  • Other conditions (secondary arthritis) – Severe damage to joints caused by conditions such as rheumatoid arthritis or gout

What is the difference between osteoarthritis and rheumatoid arthritis?

Osteoarthritis most often develops in adults who are in their mid-40s or older. It is more common in women, and people with a family history of the condition. Osteoarthritis initially affects the smooth cartilage lining of the joint. This makes movement more difficult than usual, leading to pain and stiffness. Once the cartilage lining starts to roughen and thin out, the tendons and ligaments have to work harder. This can cause swelling and the formation of bony spurs called osteophytes.

Rheumatoid arthritis is an autoimmune condition that affects more than 400,000 people in the UK. It often starts when a person is between 40 and 50 years old and causes pain and swelling in the joint. Women are 3 times more likely to be affected than men.

How does osteoarthritis affect computer (or other device) usage?

Osteoarthritis effects the joints particularly those that bear our weight (such as those in the knees and hips) as well as the joints we use a lot, such as those in the hands and wrists. Reduced or painful movement or difficulties with grip can make using a mouse difficult and reduced dexterity can make using a keyboard slow.

2. How can technology help people with osteoarthritis?

For a person with osteoarthritis, technology; computers, laptops, tablets and smartphones can offer a great way to access the world and maintain independence but using standard inputs like keyboards and mice can be difficult. However, there are many alternative ways to interact with a device that do not require you to use a standard keyboard and mouse:

  • Ergonomic keyboards
  • Ergonomic mice
  • Word prediction
  • Voice input
  • Eye gaze technology


Ergonomic keyboards

Ergonomic keyboards are keyboards designed to provide a more natural and therefore comfortable typing position; there are many different options from curved to split (where the keyboard is separated into two halves). Ergonomic keyboards are typically more suited to people who still have relatively good movement in their fingers as they do not do away with the need to type. 

See Keyboard and mouse alternatives (factsheet)

Ergonomic mice

The traditional ‘horizontal’ mouse does not place the hand and wrist in a very natural position when being used and this can often result in discomfort. Ergonomic mice adjust this position in several ways:

  • Vertical mice – this design turns the mouse grip on its side, so you grip it in a more natural ‘handshake’ position. Vertical mice tend to be fairly ‘bulky’ in size.
  • Adjustable ergonomic mice – this design allows the mouse to hinge along its length like an oyster, allowing you to adjust it to a comfortable angle.
  • Bar mice – this design is positioned directly in front of the keyboard and has a roller ‘bar’ that you control with your thumbs, tips of your fingers, or the heel of your hands.
  • Handshoe mice – this design cradles the hand removing the need for the mouse to be gripped

See Keyboard and mouse alternatives (factsheet)

Using a different design of keyboard or mouse can seem odd at first and will take a little time to get used to.

Word prediction

Word prediction is relatively common way to type quickly on smartphones and tablets but can also be used on computers and laptops. Word prediction works by seeing the first few letters of the word you are typing and ‘predicting’ the words that you may be wanting to type and presenting them to you as options. These options can be selected at any time but will be narrowed down the more of the word you type.

Voice Input

Voice input allows you to dictate rather than type into any document. You can also use your voice to ‘ask’ your computer to do things such as ‘Open Word’. Most modern versions of Windows and Mac have good in-built dictation and voice control options and voice control is available on most tablets and smartphones (iOS and Android).

See Controlling a computer, tablet or smartphone with your voice (factsheet)

Eye Gaze technology

Eye gaze technology tracks what you are looking at on the screen. It can be used to control the mouse pointer but can also be used with an on-screen keyboard to type. Eye gaze is still reasonably expensive and is typically used for significant difficulties with movement, but it is an increasingly practical solution for controlling a computer.

Other adjustments

Gel wrist rests that lie along the edge of the keyboard, mouse pads with raised gel rests or wrist ‘donuts’ (gel-filled bracelets that wrap around your wrist) can provide some additional support and comfort when using your computer and are inexpensive and widely available.

4. How AbilityNet can help you

My Computer My Way

My Computer My Way is an AbilityNet run website packed with articles explaining how to use the accessibility features built into your computer, tablet or smartphone. The site is routinely updated as new features and changes are made to the Windows, MacOS, iOS, Chrome OS and Android operating systems. The site is broken down into the following sections:

  • Vision – computer adjustments to do with vision and colour
  • Hearing – computer adjustments to do with hearing, communication and speech
  • Motor – computer adjustments to do mobility, stamina and dexterity
  • Cognitive – computer adjustments to do with attention, learning and memory
