AB - PURPOSE: With the growing elderly population undergoing TKR, digital therapeutics can play a crucial role in enhancing rehabilitation outcomes. This study assessed the usability and user requirements of the re-R digital therapeutic app for total knee replacement (TKR) rehabilitation in elderly individuals.
METHODS: Twenty-six elderly participants (aged 65 and above) were assessed using the Mini-Mental State Examination (MMSE) before using the re-R app. A usability survey was conducted, and statistical analyses, including independent-sample t-tests and correlation analyses, were conducted to examine the relationships between cognitive function, age, gender, and usability evaluation scores. Reliability analysis was conducted to assess the internal consistency among usability evaluation items. RESULTS: Participants with higher cognitive function rated the usability of the app significantly higher. The independent-sample analysis revealed a significant correlation between age and usability, economy, and awareness domains. The male and female participants had the highest scores in usability. Males had the lowest scores in economy, whereas females had the lowest scores in awareness and economy. The overall satisfaction with the re-R app was high, indicating its potential for home-based rehabilitation.
CONCLUSION: The re-R app showed high usability among elderly users, indicating its effectiveness for TKR rehabilitation. This study highlights the importance of digital therapeutics in supporting independent rehabilitation. Future studies will involve a larger and more diverse sample to determine the impact of factors such as education level, digital literacy, and frequency of smart device usage on usability.
