AidVenture: A Mobile Application Tracker for Lower-Limb Rehabilitation Integrated with Internet-of-Things based Four-Legged Walker

This study introduces a telerehabilitation system for individuals undergoing lower-limb rehabilitation, combining a mobile application and a smart walker. The AidVenture system offers a comprehensive approach to lower-limb rehabilitation to enhance the experience for patients and physical therapists. Extensive validation, which includes rigorous software development and statistical analysis, has proven the system’s effectiveness in monitoring patient progress. The user-centered design integrates advanced features such as tilt and fall detection, ensuring patient safety during exercises. Comprehensive testing has confirmed the system’s robustness and accuracy under real-world conditions, meeting all necessary standards. Additionally, the system’s practicality and readiness for clinical use have been validated through the System Usability Scale (SUS) and User Experience Questionnaire (UEQ) surveys. Functionality tests have affirmed the reliability of all system components and mobile applications. User Acceptance Testing (UAT) further highlighted the system’s usability and performance, with favorable feedback on Wi-Fi connectivity, fall detection, and overall interface design. Results showed positive results from all the functionality and usability testing done in this study.
