A Usability Evaluation of Utilizing Retro Game Design for Upper Limb Rehabilitation in Older Adults

As the global average age increases and the number of patients with frailty and degenerative joint diseases like arthritis continues to rise, rehabilitation clinics often experience congestion due to the increasing demand for rehabilitation. Promoting proactive exercise among older adults and increasing their adherence can effectively reduce the prevalence of frailty. However, attracting users to regularly engage with and ensuring an easily usable operation flow and interface design will be crucial as an effective technological solution to improve the health issues of the elderly.This study proposes an upper limb game training software with a nostalgic retro theme, the game utilizes wearable devices with sEMG and g-sensor sensors for game interaction. Older adults will actually operate the game and complete the SUS usability questionnaire. The SUS questionnaire results for this game received an A-level usability rating. Based on the SUS scores, the upper limb game training software proposed in this study has development potential. The software is easy for the older adult population to engage with, regardless of age or past rehabilitation experience, and they have the willingness to continue using it.
