Overview
Brief Summary
With aging, the elderly decreased ability to control postural balance will be accompanied by increased risk of falling (Berg et al, 1992;. Tinetti et al, 1988). According to previous studies, it showed that the elderly over 65 years fall each year probability was 30 %, and it increased with age (Skelton, & Todd, 2004). In view of this, age-related posture control has become important issues of modern preventive medicine and family care.
Detailed Description
Many clinical studies have been developed assessment tools and measurements for clinical staff to provide balanced assessment and intervention. However, the factors of affecting postural control are diverse and complex, not all tools or measurement could effectively detect a risk of falling. In daily living, the postural control involved integration of sensation, biofeedback, movement response, and kinesthetic sense to maintain postural stability, and finally integrated into the neuromuscular system and coordination to help achieve the perfect postural control. Current clinical tools used to assess the fall or research methods to detect the incidence of falls and the lack of effective relevant and contradictory, and it's difficult to effectively evaluate the risk of falls (Gates, et al, 2008). With the development of postural balance issues associated with aging process in older people, there is no set of standardized equipment, and lack of effective methods for the assessment of normal and older people who fall. In response to these problems, if we can provide a virtual reality interfaces, and with daily living activities as gait, across obstacles activity, sit to stand, will be able to better meet the desire to explore the issue of real significance to enhance researchers for aging, motion analysis, and brain cortex activity mechanism in postural control mechanism.
