Description

An Internet-based walking device to prevent elderly people from falling and its fall risk simulation method

Technical Field

The present invention relates to the technical field of auxiliary walking prediction equipment, and in particular to an Internet-based walking device for preventing the elderly from falling and a fall risk simulation method thereof.

Background technique

Fall refers to a sudden, involuntary, and unintentional change in body position of an individual, falling to the ground or a lower plane. As the world's population ages, human life expectancy increases, and the physiological changes associated with the aging process, such as decreased physical function, balance, and limb coordination, as well as the presence of other factors such as diseases, drugs, and cognitive impairment, increase the tendency of the elderly to fall and get injured from falls. According to relevant research reports, about one-third of the elderly fall each year, and the incidence of falls in the elderly over 80 years old is as high as 50%. The medical economic burden required for injuries caused by falls is serious, and each fall incident causes an average medical and health economic loss of about US$1,049. The injuries caused by falls range from abrasions, bruises, sprains or strains to fractures, craniocerebral injuries, and even death. Relevant epidemiological surveys show that falls are the second leading cause of injury-related death among the elderly worldwide, and the leading cause of injury-related death among the elderly over 65 in my country.

Falls in the elderly are often affected by a variety of internal and external factors, including gender, age, history of falls, disease factors, drug factors, sensory function, gait balance, muscle strength, cognitive function, psychological factors, home environment factors, etc. Assessing the risk of falls in the elderly and identifying key factors and high-risk groups for falls are the prerequisites for implementing targeted interventions. Currently, the commonly used fall risk assessment tools for the elderly mainly include fall risk assessment scales, fall risk monitoring equipment and fall risk assessment models. However, the fall risk assessment scale covers limited factors, and the sensitivity and specificity for predicting the occurrence of falls are low. The fall risk assessment based on gait analysis, balance ability testing and other equipment is highly dependent on professionals, and there are certain potential safety hazards in the assessment process. The existing fall risk assessment models are often not representative enough in terms of sample sources, and the incidence of falls among the elderly is far lower than the actual value, resulting in poor prediction accuracy and limited promotion and application. Therefore, how to overcome the limitations of existing research and explore and build a more practical, more accurate, and easier to operate and promote fall risk prediction simulation device for the elderly is still the direction of efforts of the majority of medical workers. Therefore, this device provides an Internet-based walking device for preventing falls in the elderly and a fall risk simulation method thereof.
