Chronic conditions, including cardiovascular diseases, diabetes or physical injuries due to falls and other accidents have significant costs for people, the healthcare system and the Canadian economy. However, close monitoring of chronic conditions can significantly reduce their effects. In addition, regular activity and exercise in older adults is associated with an overall improvement in health, functional capacity, quality of life and independence. Research in TECH-DD is producing technologies and tools that will help to actively engage older adults in society. We are developing novel ambient-based and on-person technologies that can measure physiological and activity data; systems that can mitigate the risk of injury from accidents, such as falls; and new technological platforms for exercise and prevention of injury and disability. These technologies will be transferred to market through our industry partners. Results will also inform new approaches to improve care practices and reduce healthcare expenditures.
