World Stroke Day

One in four of us will have a stroke in our lifetime. Stroke survivors often have problems with physical mobility, eating, speech and language, emotions and thought processes. World Stroke Day is held annually on 29 October to raise awareness of stroke prevention, treatment, and the support stroke survivors need.

Stroke can affect movement, vision, speech, cognition, and memory in different combinations, so no single user story captures the full range. As one example of motor impact on web use, the W3C Web Accessibility Initiative’s user story for Ade, a reporter with limited use of his arms, describes adaptive strategies that also apply to many people after a stroke: a joystick operated with the palm of the hand, a keyboard with larger keys used one finger at a time, and speech recognition software. Each has trade-offs — joysticks are inaccurate on small targets, extended keyboard or joystick use is tiring, and speech recognition only works reliably when links and controls are clearly labelled and coded correctly.

Websites that work well for people with similar access needs provide a clearly visible keyboard focus indicator, a tab order that matches the visual order of the page, popups and dialogs that can be closed with the keyboard (including by pressing Escape), long forms that can be paused or extended rather than timing out, and skip links that move focus past repeated navigation. Plain language, clear headings, and consistent layouts also help people whose stroke has affected cognition, language, or memory.
