Due to home accidents occurring within the world's aging population, especially with the accidental stumble and falling of the elderly, mortality and morbidity from falls have become one of the major issues in the health care system. In most developed countries, most frequent stumbles and falls occur in and around the community or at home. A number of wearable devices integrated with accelerometers...
Gait velocity has been shown to quantitatively estimate risk of future hospitalization, a predictor of disability, and has been shown to slow prior to cognitive decline. In this paper, we describe a system for continuous and unobtrusive in-home assessment of gait velocity, a critical metric of function. This system is based on estimating walking speed from noisy time and location data collected by...
Falls are among the most frequent occasions happening on elderly. Moreover, falls can cause fatal effect on them. One of the issues related to elderly health, which can incur falls, is the gait characteristics. Thus, it will be useful to set up a monitoring system for home-use to detect the gait characteristics of the elderly. With this daily monitoring system, the changes in gait characteristics,...
Today, elder care demands a greater degree of versatility in healthcare. Automatic monitoring devices and sensors are under development to help senior citizens achieve greater autonomy, and, as situations arise, alert healthcare providers. In this paper, we study gait patterns based on extracted silhouettes from image sequences. Three features are investigated through two different image capture perspectives:...
There are more and more researches on walking stability analysis for health management of elderly people. This study presents a definition and an assessment of human walking stability. Its main objectives are to propose a technique to quantify local dynamic stability, and to study the relationship between walking stability and age in developing an understanding of normal gait. Dynamic Time Warping...
Characteristics of physical activity are indicative of one's mobility level, latent chronic diseases and aging process. Current research has been oriented to provide quantitative assessment of physical activity with ambulatory monitoring approaches. This study presented the design of algorithm integrated with a portable microprocessor-based accelerometry measuring device to implement real-time physical...
Americans are living longer, and research shows that seniors are embracing independence, and will benefit from living in the same place. These are the rationale for 'Aging in Place' and the development of Tiger Place, an 'Aging in Place' Environment in Columbia Missouri. Our goal is to minimize intrusion, allow the resident complete control over privacy and treatment (if any), and to provide substantive...
