Abstract
Many individuals with stroke experience upper-limb motor deficits, and a recent trend is to develop novel devices for enhancing their motor function. This study aimed to develop a new upper-limb rehabilitation system with the integration of two rehabilitation therapies into one system, digital mirror therapy (MT) and action observation therapy (AOT), and to test the usability of this system. In the part I study, the new system was designed to operate in multiple training modes of digital MT (i.e., unilateral and bilateral modes) and AOT (i.e., pre-recorded and self-recorded videos) with self-developed software. In the part II study, 4 certified occupational therapists and 10 stroke patients were recruited for evaluating usability. The System Usability Scale (SUS) (maximum score = 100) and a self-designed questionnaire (maximum score = 50) were used. The mean scores of the SUS were 79.38 and 80.00, and those of the self-designed questionnaire were 41.00 and 42.80, respectively, for the therapists and patients after using this system, which indicated good usability and user experiences. This novel upper-limb rehabilitation system with good usability might be further used to increase the delivery of two emerging rehabilitation therapies, digital AOT and MT, to individuals with stroke.

We successfully developed an innovative system (i.e., mode stroke rehabilitation (MSR)) by combining two promising interventions, digital action observation therapy (AOT) and mirror therapy (MT), for patients with stroke
Summary
Many individuals with stroke experience upper-limb motor deficits, and a recent trend is to develop novel devices for enhancing their motor function. Some studies have recorded movements executed mainly by the non-affected hand of patients, immediately transformed the actions of the non-affected hand, and presented them on a screen or in goggles via cameras, webcams, or virtual reality technology17,19,21,23–25 This approach using real-time video-captured images broadens the diversity of movements and functional tasks and allows the users to record individual videos by themselves, which helps to overcome some limitations of conventional MT and AOT. These studies have demonstrated the benefits of these devices or systems in improving upper-limb motor impairments in patients with stroke. Computer-mediated visual feedback and stimuli (e.g., images or videos) may strengthen the clinical utility of MT and AOT
