Abstract

<p>It has been reported that finger dexterity and cognitive function decline with aging and are related to each other. In our previous study, we developed a training device (iWakka) for adjustability for grasping force. In this study, we developed the iWakka Healthcare System, which provides training for hand dexterity and cognitive function at home using iWakka and allows healthcare professionals to check the daily implementation status. Using this system, a 30-day intervention study was conducted at home with 14 community-dwelling older people to investigate changes in their adjustability for grasping force, cognitive function and verify usefulness of the system. Cognitive function was assessed in executive, attention, and memory functions. The results showed significant improvement in adjustability for grasping force and cognitive function. A process of motor learning over 30 days could be quantified in 11 subjects with approximate curves representing exponential decay. It was found that memory function before the intervention affected the process of motor learning. These results suggest that the iWakka healthcare system may contribute to improving adjustability for grasping force and cognitive function.</p>
