【摘要】：脑性瘫痪是由于出生前、出生时、婴儿早期的某些原因造成的非进行性脑损伤所致的综合症。目前各国脑瘫发病率较高，发病原因有很多种，但是具体的发病机制尚不清楚。脑瘫主要临床表现是中枢性运动功能障碍和发育滞后。康复治疗有助于让脑瘫患者最大限度地恢复残疾的正常功能，而康复评价是康复治疗的一个重要环节，准确有效的评估是使脑瘫患儿得到理想治疗结果，保证生活质量的重要环节。目前对于脑瘫的评估方式主要有运动功能粗大量表、表面肌电描记术以及步态分析等，但是这些评估方式都不能对脑瘫进行早期的定量诊断评估，这就导致对于脑瘫疾病发现较晚，严重影响了婴幼儿康复训练的效果。针对这一现状，，本文设计开发了一种用于膝爬运动参数定量分析的软件系统，以实现对婴幼儿早期运动功能进行客观评价。本文在总结分析了目前应用软件设计开发规范，针对重庆医科大学附属儿童医院提出的“对具有膝爬能力的婴幼儿进行定量评估”的应用需求，以瀑布模型结合演化模型为基础，在LabVIEW平台上设计开发了三维膝爬姿态分析及可视化系统应用软件。该系统基于事件结构的人机界面设计模式，编程实现了两大功能：同步显示关节活动角度曲线与三维动态效果；对比显示正常儿童的关节活动角度范围与被试儿童的关节活动角度曲线。本文利用黑盒测试法，分别对软件功能进行了模块测试和组合测试。模块测试结果表明软件能够实现被试儿童与正常儿童关节角度的对比显示，以及膝爬姿态的关节角度曲线与三维动态效果与的同步显示。组合测试证实了本系统主程序界面能够将主程序中的患者的信息传递到同步显示这一子VI中，实现主程序与子VI之间的数据传递。在实际应用时，本文以正常儿童和脑瘫儿为实验对象，进行膝爬实验，用运动捕捉系统捕捉了膝爬时各关节的主要活动数据，利用本软件对得到数据进行处理，并对比分析了正常儿童与脑瘫患儿的结果差异，结果表明本软件能够对膝爬运动时关节的活动角度进行评估。本文设计开发的软件与三维步态分析系统有良好的系统兼容性，为三维步态分析系统增加了对于膝爬运动定量评估的功能，为脑瘫儿运动功能早期诊断和康复评价提供了新的技术手段。
[Abstract]:Cerebral palsy is due before birth, birth, causing some cause of infant early non induced brain injury syndrome. The incidence of cerebral palsy, there are many causes, but the specific pathogenesis is still unclear. The main clinical manifestations of cerebral palsy is the pivot movement dysfunction and rehabilitation development lags behind. Help the cerebral palsy patients to maximize the restoration of normal functional disability, and rehabilitation evaluation is an important part of rehabilitation therapy, accurate and effective assessment is to get ideal results in treatment of children with cerebral palsy, an important link to ensure the quality of life.
At present, for the assessment of cerebral palsy are mainly coarse motion function of a large number of tables, surface electromyography and gait analysis, but these methods are not quantitative evaluation of early diagnosis and evaluation of cerebral palsy, which leads to cerebral palsy disease found late, serious impact on the infant to the effect of rehabilitation training. In view of this situation, this paper design and development of a software system for knee climbing motion parameters of quantitative analysis, the objective evaluation of the early exercise function in infants to achieve.
This paper analyzes the current development and application of design software specification in summary, aiming at the children's Hospital Affiliated to Medical University Of Chongqing "quantitative assessment" of the ability of infants with knee climbing application needs to waterfall model combined with the evolutionary model, design and development of 3D knee climbing application software attitude analysis and visualization system on the LabVIEW platform. The system the man-machine interface design model based on event structure, realizes two functions: synchronous display of joint activities in the perspective of curve and 3D dynamic effect; contrast display normal children joint movable angle and the children were the joint angle curve.
In this paper, using the black box testing method, respectively. The functions of the software module test and combined test module. Test results show that the software can realize the contrast test of normal children and children with joint angle, knee joint angle and climb attitude curve and 3D dynamic effect and synchronous display. Combined testing proved that the system main program interface the main program in the transmission of information to the synchronous display of this sub VI, realize the main program and VI data transfer.
In practical application, based on the normal children and children with cerebral palsy as the experimental object, knee climbing experiment, capturing the knees main activities of the joint data using a motion capture system, the data were processed by the software, and the comparative analysis of normal children and children with cerebral palsy and the difference between the results. The results show that the software can to evaluate the angle of knee climbing movement.
The software developed in this paper has good system compatibility with the three-dimensional gait analysis system, and provides a quantitative evaluation function for the three-step gait analysis system. It provides a new technical means for early diagnosis and rehabilitation evaluation of cerebral palsy children's motor function.
