How can PTs ensure accessibility of digital communication for people with disabilities?

• A. Require high-speed only
• B. Captions, screen-reader compatibility, keyboard navigation, and alt text for images
• C. Only rely on video
• D. Disable captions

Answer: (B)

Making digital communication accessible means designing for diverse abilities so people with disabilities can access information independently and safely. For physical therapists, this involves several practical steps that broaden who can engage with patient education, telehealth, and portals.

Captions on instructional videos ensure someone who is Deaf or hard of hearing can follow along with the content. Screen-reader compatibility means the text and structure are described to someone who relies on assistive technology, so they understand what’s on the page or screen. Alt text for images provides a descriptive alternative for people who cannot see the image, conveying essential information or instructions. Keyboard navigation guarantees that all interactive elements—forms, menus, and buttons—can be reached and operated without a mouse, which helps those with motor disabilities or those who use alternative input devices. When combined, these practices make digital materials perceivable, operable, and understandable, supporting meaningful participation in care.

In practice, this means using clear headings and semantic markup, providing text alternatives for media, ensuring readable color contrast, and testing interfaces with assistive technologies. These steps enable more patients to access exercise instructions, appointment information, and telehealth visits. Requiring only high-speed access or relying solely on video, or disabling captions, would leave many people unable to use the materials effectively.
