Normal Human Static Balance Function Analysis And Evaluation Of The System Is Initially Established

The balanced function is refers to the bodily self-adjustment center of gravity and maintains the posture stable one kind of capability. People sits, stand, line and other daily activities are based on the complete balance function. However, the apoplexy, hemiplegics, the skeleton damage, the diabetes and other diseases often can lead to balance dysfunction. With advances in medical technology, a variety of disease prevention, treatment and rehabilitation ladder, and pushed forward the process of human aging society, the disabled, lesions, and the relative risk of disability increases. Therefore, the clinical application of balance function test increases people's attention.Since the mid-19th century, foreigners start to study on balance function. People started to use the pressure plate technology evaluation balanced function in the 1970s. And this has opened the history of the quantitative investigation balanced function. So far, there are hundreds of static balance function index. The test posture has the difference respectively. And the evaluation criteria have different explanations too. But there is no key index to reflect the overall balance function. This paper collects the previous evaluation criteria. Through mass data gathering and the statistical analysis, this paper proposed the key index which can reflect the overall balance from a large number for alternative indexes. The main content includes as follows.1. The balancing apparatus' design. Through analyzing the design requirements of the human balanced function testing equipment, this paper develop a balanced apparatus to meet the research needs and establish the alternative evaluation index set of balance function.2. The first filter of repetitive analysis of the balance testing index. This paper selects a few people to repeat the test which is in order to verify the repeatability balance test system of the human being. By repetitive statistical validation, a large number of test targets on a preliminary screening, good indexes of reproducibility are retained and bigger changes of the larger indexes are excluded.3. The second filter based on the trend map of age-balance testing index. The map of the age changed of different indexes is drawn based on the initial filter of the balance function index. The messy indexes of changed age are removed and the stronger indexes are retained. The best age group is selected from the relationship between the balance function and the age. Analyze the relationship between the age and index of each people who is more than the best crowd. And sort the related coefficient based on size. The second filter of the balanced evaluation index is completed based the proposed system analysis.4. The third filter of the principal component analysis on the balance testing index. Based on the second filter, the principal analysis is done to the entire crowd. And the key index is selected by the variance of different indexes which are sorted.5. Establish the scoring criterion. Based on the evaluation index system, the age distribution map of different indexes is drawn. The criterion is established according to the number of principal component analysis of factor and the variance and standard deviations of the key index.
