Abstract

The invention belongs to the technical field of rehabilitation medicine protection and particularly relates to a method for evaluating the balance capacity of old people. The method includes the following steps that A, experimental subjects are grouped into a normal group, a low-risk group, a middle-risk group and a high-risk group according an old people balance capacity test scale, plantar pressure distribution generated when the old people sit up is detected through a plantar pressure distribution detecting system, and cushion pressure generated when the old people sit up is detected through a cushion sensor; B, the old people walk on a three-dimensional dynamometry table, and kinematics parameters of the gaits generated when the old people walk are acquired through the three-dimensional dynamometry table, wherein the kinematics parameters comprise the pressure and torque in the foot vertical direction, the pressure and torque in the foot front-and-back direction and the pressure and torque in the foot inside and outside directions; C, sample entropies of the plantar pressure and torque during sitting up and walking are subjected to statistic analysis, the significant difference of the correlativity between the variable sample entropies is found, and an objective evaluation standard is obtained. The method has the advantage of being capable of evaluating dynamic balance of the old people.

Description

technical field

[0001] The invention belongs to the technical field of rehabilitation medicine protection, and in particular relates to a method for evaluating the balance ability of the elderly. Background technique

[0002] According to the World Health Organization (WHO), about 424,000 deaths are directly related to falls every year in the world, and falls are the second leading cause of unintentional injury deaths in the world (after traffic accidents). Studies have shown that among the elderly over 65 years old, the proportion of one or more falls per year is as high as 1 / 3, and 20-30% of them will cause bruises, hip fractures, head injuries, etc. during falls. External trauma, etc., and increase with age. In the United States, the total medical cost of falls exceeds $20 billion per year. At present, there are about 130 million elderly people in my country, about 20 million elderly people have at least 25 million fall accidents every year, and the direct medical expen...

Embodiment Construction

[0040] The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] An actual verification of this program was carried out in Malianwa Community (one of the communities with the highest proportion of elderly population in Beijing), and a total of 128 subjects participated in the experiment. According to the balance ability test score of the elderly, 55 normal persons, 49 low-risk persons, 23 medium-risk persons, and 1 high-risk persons were obtained. Each experimenter was examined by a doctor, and the examination results were written into the medical record report, which included: age, weight, history of falls, history of medication, relevant medical history, and degree of sensory impairment. Generally, in addition to balance and gait pro...
