Repetitive Strain Injury

Repetitive Strain Injury (RSI) is a general term used to describe the pain felt in muscles, nerves and tendons caused by repetitive movement and overuse. The condition mostly affects parts of the upper body, such as the forearms, elbows, wrists, hands, neck and shoulders.

RSI is a significant concern in the digital accessibility community because it directly affects how people interact with computers and other devices. People with RSI may find it painful or impossible to use a traditional mouse and keyboard for extended periods.

RSI and accessibility

Assistive technologies and accessible design practices can help people with RSI continue to use digital products comfortably. These include:

• Voice recognition software that reduces the need for typing
• Keyboard shortcuts that minimise repetitive mouse movements
• Ergonomic input devices such as vertical mice and split keyboards
• Screen readers and switch devices for severe cases

Web developers and designers can support people with RSI by ensuring their products are fully keyboard-accessible and do not require precise, repetitive mouse interactions.
