The usability of a video feedback-based walking aid skills training program: a multi-method study

Area of Science:

• Rehabilitation technology
• Digital health interventions
• Mobility aids training

Background:

• Effective training in walking aid skills is crucial for users with mobility impairments.
• Existing training methods may have limitations in accessibility and engagement.
• Mobile applications offer a novel approach to supplement traditional rehabilitation education.

Purpose of the Study:

• To evaluate the usability of an interactive video-based mobile application for teaching walking aid skills.
• To assess user perceptions of ease of use and usefulness for individuals with diverse needs and experiences with walking aids.

Main Methods:

• A multi-method study involving a novel interactive video-based mobile application.
• Participants used the app twice over two weeks.
• Usability assessed via System Usability Scale (SUS) and thematic analysis of semi-structured interviews.

Main Results:

• Twelve participants (mean age 54.2 years) completed the study.
• The mean SUS score was 88.3, indicating high usability (96th-100th percentile).
• Key themes included experiences with training, perceived ease of use, usefulness, and app usage motivations.

Conclusions:

• The interactive mobile application demonstrated high usability among walking aid users.
• The app is perceived as an easy-to-use and useful tool for learning and maintaining walking aid skills.
• User feedback suggested enhancements, such as incorporating an audio component.
