【摘要】：老年人隨著年齡的增長(zhǎng)肌肉骨骼機(jī)能逐漸衰退,維持平衡能力日漸降低,逐步喪失日常的自理生活能力,而站立行走的平衡能力是人們獨(dú)立生活的先決條件,因此平衡能力評(píng)測(cè)的準(zhǔn)確性和客觀性尤為重要。目前,臨床上對(duì)人體平衡能力評(píng)測(cè)的方法中大多數(shù)還集中在平衡量表法。此方法依賴醫(yī)師的經(jīng)驗(yàn),有很強(qiáng)的主觀因素,對(duì)人體平衡能力的評(píng)測(cè)準(zhǔn)確性還存在一定的不足。本研究主要針對(duì)平衡能力評(píng)測(cè)方法中的不足做了如下工作:第一,本文闡述了人體靜態(tài)平衡能力評(píng)測(cè)系統(tǒng)。本文利用力檢測(cè)平臺(tái)裝置采集人體重心運(yùn)動(dòng)軌跡,采用以QNX為核心的實(shí)時(shí)操作系統(tǒng)和工業(yè)級(jí)的PC/104控制器來構(gòu)建評(píng)測(cè)系統(tǒng),對(duì)被測(cè)者分別要求睜眼和閉眼兩種狀態(tài)進(jìn)行重心數(shù)據(jù)采集。第二,本文應(yīng)用功率譜密度理論原理,將橫軸頻率劃分為三段,分別是(0.02~0.2Hz)、(0.2~2Hz)、(2~10Hz),分別研究每段頻率上老年組和青年組分布情況,計(jì)算功率譜百分比構(gòu)成,最后綜合分析老年組和青年組的平衡能力。第三,本文將人體靜態(tài)平衡和混沌理論相結(jié)合,研究人體靜態(tài)平衡機(jī)能穩(wěn)定性,分析視覺,性別,及年齡對(duì)平衡穩(wěn)定性的影響。本研究過程中,采集了一定量的青年組和老年組的實(shí)驗(yàn)數(shù)據(jù),并對(duì)他們的實(shí)驗(yàn)數(shù)據(jù)提取主要特征,分別從時(shí)域和頻域兩方面分析和比較他們的異同點(diǎn)。根據(jù)實(shí)驗(yàn)結(jié)果分析得到老年組和青年組在不同的方法中所表現(xiàn)出的平衡能力差異。
[Abstract]:As the elderly age, their musculoskeletal function declines, their ability to maintain balance decreases, and they gradually lose their ability to live on their own, and the ability to stand and walk is a prerequisite for people to live independently. Therefore, it is very important to balance the accuracy and objectivity of ability evaluation. At present, most of the methods of evaluating the balance ability of human body are focused on the balance scale. This method relies on the doctor's experience, has very strong subjective factor, and has certain deficiency to the human body balance ability appraisal accuracy. The main contents of this study are as follows: first, this paper describes the static balance ability evaluation system of human body. This paper uses the force detection platform device to collect the human body center of gravity motion track, using QNX as the core of the real-time operating system and industrial PC/104 controller to build the evaluation system. The subjects were asked to open their eyes and close their eyes to collect the barycenter data. Secondly, based on the theory of power spectral density, the transverse axis frequency is divided into three sections (0.02~0.2Hz), (0.2~2Hz), (2~10Hz). The distribution of the old and young groups on each frequency segment is studied, and the percentage of power spectrum is calculated. Finally, the balance ability of the aged group and the young group was analyzed. Thirdly, this paper combines the theory of human body static balance with chaos theory to study the stability of human body static balancing machine, and to analyze the influence of vision, sex and age on the balance stability. In the course of this study, a certain amount of experimental data were collected from the young group and the old group, and their main characteristics were extracted, and their similarities and differences were analyzed and compared from the time domain and the frequency domain respectively. According to the analysis of the experimental results, the difference of the balance ability between the aged group and the young group in different methods was obtained.
