The present invention relates to one type; room & W7 can. 钵 · ^上· „ About the unified system. The present invention provides a human-computer interaction mode, which can help train the upper limb movement of the patient. Techniques] The defect of upper limb movement after stroke is one of the most important sequelae. About 2/3 of stroke patients will have functional defects of upper limbs. In the initial stage of stroke, there will be 8% of patients with upper limb function defects. 4% of patients with upper extremity dysfunction still exist, so in the recovery period of upper limb motor function in patients with hemiplegia, there will often be a lack of function, which affects the performance of daily life function. How can effectively evaluate patients with stroke hemiplegia The upper limb function is an important issue for rehabilitation professionals. However, the common upper limb problems of patients after stroke have muscle tension changes, abnormal coordinated movements, and lack of coordination between joints. Therefore, when these patients move up the upper limbs, there will be slow and uncoordinated movements that are different from ordinary people, resulting in inconvenience in life. It is often used as an evaluation method for upper limb function after stroke. The motion analysis system commonly used in rehabilitation of upper limb movements includes 201121525 VICON, FASTRAK and other spatial analysis systems, which have the advantage of measuring more parameters and accuracy. High, but the disadvantage is to install multiple sensors in a fixed space's time spent setting up and subsequent data analysis, and need to be accompanied by professionals. There are also commonly used upper limb rehabilitation assessment scales like Fugl_meyer, Bmnnstrom Ashworth, etc., can assess the upper limb function level of patients, but it also requires professionals to accompany the assessment, which takes more manpower and time. However, the common point of these assessment tools is to be able to assess the functional function of the upper limb movement of the patient. Although they have their application value in related clinical research, if a simple use of the upper limb motion evaluation system can be established, it can be provided as a reference for clinical physiotherapists, which can benefit more patients and reduce The pressure of the therapist. [Disclosed] The technical problem to be solved by the present invention
在現有技術中，針對上肢功能的評估已有光學動作分 析系統以及專業評估量表（Fugl-meyer、Brunnstrom)等方 式，但這些現有技術皆必須有專業人員的陪同下操作，而且 光學動作分析系統成本高。 由於臨床上物理治療師評估上肢功能是否有缺損，往 往只能依賴一些量表進行評估，而可以提供客觀的上肢運動 學參數之動作分析系統又十分昂貴且不易操作。故本研究提 供一個操作方便、成本低廉的簡易上肢功能評估與訓練之系 統。藉由量測不同的上肢功能損傷的患者，比較其運動學斗寺 徵與上肢功能的關係’以運動學的特徵評估上肢功能，達至】 201121525 簡易上肢功能評估的目的，並可提供給臨床人員做為參考的 依據。 本發明之另一目的係提供一種有效的臨床評估中風病 患上肢動作功能之系統，利用加速規和電子尺以及相關資料 擷取完成本發明之系統架構，將有助於減少中風病患上肢動 作功能的殘留缺失及提升日常生活功能的表現，進而促進中 風病患的生活品質。 本發明解決問題之技術手段 本發明為解決習知技術之問題所採用之技術手段係在 受測者上肢的肩膀肩峰處與手腕處設置適當數量的加速規 ，一電子尺之第一端定位在適當固定的地方如受測者上肢肩 膀，而第二端係定位在欲評估訓練之處如受測者上肢手腕。 該加速規及電子尺所感測的類比訊號經資料擷取介面及類 比至數位轉換器後送至一電腦平台。利用加速規和電子尺等 感測器的特性，搭配電腦平台的虛擬實境的人機介面視覺回 饋的方式，提供上肢功能缺損的所有患者，如中風偏癱患者 可以進行這樣的方法來評估以及訓練，經由系統分析後取得 量化參數的結果，再利用視覺回饋的方式達到訓練的目的， 最後再交由臨床治療師做為參考的依據。 本發明對照先前技術之功效 本發明是以操作方便、成本低廉為系統需求，藉由三 軸加速規以及電子尺的特性，結合人機介面來評估中風偏癱In the prior art, the evaluation of the upper limb function has an optical motion analysis system and a professional evaluation scale (Fugl-meyer, Brunnstrom), etc., but these prior art must be accompanied by a professional operation, and the optical motion analysis system high cost. Because clinical physiotherapists assess whether there is a defect in upper limb function, they can only rely on some scales for evaluation, and an action analysis system that provides objective upper extremity kinematic parameters is expensive and difficult to operate. Therefore, this study provides a system for easy evaluation and training of simple upper limb functions that is easy to operate and low in cost. By measuring the difference of upper limb functional impairment, the relationship between the kinetics of the martial arts and the function of the upper limbs is evaluated. The upper limb function is evaluated by the characteristics of kinematics. 201121525 The purpose of simple upper limb function assessment can be provided to the clinic. The basis for personnel as a reference. Another object of the present invention is to provide an effective clinical evaluation system for the upper limb movement function of a stroke patient, and using the acceleration gauge and the electronic ruler and related data to complete the system architecture of the present invention will help reduce the upper limb movement of the stroke patient. The lack of function remains and enhances the performance of daily life functions, thereby promoting the quality of life of stroke patients. Technical Solution for Solving the Problems The technical means adopted by the present invention to solve the problems of the prior art is to provide an appropriate number of accelerometers at the shoulder shoulders of the upper limbs of the subject and the wrist, and the first end of the electronic ruler is positioned. In a properly fixed place such as the shoulder of the upper limb of the subject, and the second end is positioned at the place where the training is to be evaluated, such as the wrist of the upper limb of the subject. The analog signal sensed by the accelerometer and the electronic ruler is sent to a computer platform through the data acquisition interface and the analog to digital converter. Using the characteristics of sensors such as accelerometers and electronic rulers, and the virtual reality of human-machine interface visual feedback on the computer platform, all patients with upper limb function defects, such as stroke hemiplegia patients, can be evaluated and trained. After the system analysis, the results of the quantitative parameters are obtained, and then the visual feedback is used to achieve the purpose of training, and finally the clinical therapist is used as a reference. The present invention compares the efficacy of the prior art. The present invention is based on the convenience of operation and low cost, and the characteristics of the three-axis acceleration gauge and the electronic ruler are combined with the human-machine interface to evaluate the stroke hemiplegia.

Through the network video instructions to do more advanced step-up training exercises, so that stroke patients do not use 4 doctors to return to the doctor, it really reduces the waste of medical resources. Other objects and effects of the present invention will be further clarified by the following examples and accompanying drawings. 201121525 [Embodiment] > FIG. 1 is a schematic diagram of a circuit system of the present invention. The upper limb motor function evaluation and training system of the stroke hemiplegic patient of the present invention includes a first acceleration gauge U, a second acceleration gauge 12, an electronic scale (P〇tenti〇meter), a data capture interface 14, and an analogy. To the digital converter 15, a computer platform 16. The computer platform 16 can be a general commercial computer system or a special (four) bit control system, which can be configured - a display 17 and a memory device 18. The first acceleration gauge u, the second accelerometer 12, and the electronic scale η are connected to the data capture interface 14, and the analog capture signal of each sensor is taken by the data capture interface 14, and the analogy to the digital converter 15 The analog signal is converted to a digital signal and sent to the computer platform 16 for analysis. The first accelerometer 11 and the first accelerometer 12 can adopt the two-axis accelerometer of the commercial ADXL330, which uses the MEMS micro-electromechanical operating voltage to support the low-voltage production of 1.8-3.6V, the highest detectable The gravity acceleration of the soil is measured by a static capacitance induction type. The electronic ruler 13, also known as a potentiometer, can be used to measure displacement. The most important feature of the electronic ruler is linearity. The so-called linearity is the distance between each movement of the swing arm. The precision resistor inside will produce a voltage change proportional to the distance, regardless of the amount of the arm. The invention uses the electronic ruler 13 with the acceleration gauges 11, 12 for the measurement and analysis of the upper limb motion and the training of the visual feedback. Since the electronic ruler can measure the linear motion, the acceleration gauge can measure the three-dimensional motion, and the appropriate The electronic ruler is equipped with an accelerometer placement position to measure linear linearity and angle changes, such as: forward hand movement, hand movement to the side, hand movement 201121525 action, and so on. The data capture interface 14 can be implemented by the commercial NI pci_62n data manipulation interface (DAQ) and its extended version CB_68LpR, and the analog type electrical signals of the respective sensors are processed to the computer platform 16 for analysis. The DAQ card has 16-bit resolution, 250k/s sampling rate, and 16 analog input channels. It can simultaneously operate the first acceleration gauge, the second acceleration gauge 12, and the electronic scale 13 & signal for subsequent processing. The analysis interface 14 can also be used to measure the interface φ as a data transmission interface, which can make the whole system more portable. The software used in the computer is the LabVIEW as a human-machine interface and the numerical analysis program is used to create a human-machine interface. A virtual instrument with similar appearance and operation to the actual instrument can be designed. Referring to Figure 2, before the upper limb assessment of patients with stroke hemiplegia, let the subject 2 (a stroke hemiplegia patient) sit at the appropriate distance in front of the test table 3, and at the wrist of the affected person 2 on the affected side 21 Wear the active wristband of the Devil's number, set the first acceleration gauge n on the shoulder of the shoulder (嶋mi— • position, fixed with breathable tape, and the second acceleration gauge 12 is set on the wrist of the wrist. In the middle of the styloid process (radial styi〇id pr〇ces〇 and ulnar styloid process (η〗 (10)犷_〇id pr〇cess), and the middle finger extension line is fixed with the devil's felt and breathable tape. The second end 13a of the electronic ruler 13 is fixed on the shoulder clavicle of the affected side 2, and the second end of the electronic ruler 13 is fixed at the position of the styloid process of the wrist of the subject 2 _ 21, using the devil's dry and the ventilated temperament After placing all the sensors, you can use the elastic bandage to fix the torso of the tester 2. Measure the length of the 2 f arm of the subject and the length of the upper and lower arms of 201121525 degrees, and record and place a target on the table. 4, the position that the subject can take 2 hands #length and can be grasped. The purpose of the object 4 is to enable the subject 2 to have a target during the experiment, so that the subject 2 can smoothly obtain the data. When performing the rehabilitation evaluation and training, the display 17 can provide a human-computer interaction. Feedback on the human-machine interface. As shown in Figure 3, the starting point of the subject's 2 hand forward is ρι = = 2, the elbow angle is fixed at 90 degrees (no degree), the hand corner = The method of measuring is based on the 01ecranon process as the original point. The angle of the shoulder of the shoulder is measured at the angle of the shoulder and the styloid process of the wrist. The hand is terminated. The maximum distance, while the stroke patient accepts (four) t the front side reach distance is based on the distance that can be achieved by the active action. Setting: The tester 2 sits on the chair in front of the test table 3 to complete each sensor: Evaluation step. Subject 2 hears the test start indication ', and touches the most advanced way to touch the end point that has been set at the forefront, and puts the action on the table along the test table 3 to draw the upper and middle movements. Just try to stretch in the dry down.

The affected side 2' ΐ one hand without the system The experimental test items of 仃 can also be: (1) and the side of the healthy side 22 grasping the target of the horizontal tabletop; (2) the affected side 21 hands when asked to reach the target of the horizontal table; (3) 201121525 The affected side 21 is operated by one hand. After reaching the target of the horizontal table, it is raised to a level higher than the shoulder plane. (4) Both the affected side 21 and the healthy side 22 are operated at the same time. After reaching the target of the horizontal table, the height is raised. On the shoulder plane. In the course of the experiment, if the subject's item and the second item are difficult, the test items of items 3 and 4 will not be tested. The data acquisition interface 14 extracts the analog signal of each sensor in the project for each experimental test, and transmits it to the analog to digital converter 15 to convert the analog signal to the digital signal, and then the computer platform The machine interface and the numerical analysis program 161 display useful quantization parameters on the virtual instrument, such as: the distance of the displacement, the maximum acceleration value, the maximum speed value, the hand angle, the total movement time, etc. Using the human machine interface and The numerical analysis program 161 records the process, and records three times for each test, and then analyzes and evaluates the results. The system evaluation method is to analyze the relationship between the kinematic characteristics of the hand-stretching action during the experimental start-to-end point. (8) The kinematic parameters can include parameters such as acceleration == shift. Finally, the function of the upper limb is evaluated by statistical analysis. The kinematic parameter data 181 can be stored in the memory device 18 or can be further transmitted to other analysis systems. For further numerical analysis. In the virtual design interface of the experiment, the parameters with displacement are used to represent the hand extension of the subject. The degree of the three-axis accelerometer signal and the acceleration value of each axis can be expressed on the virtual instrument interface. When the subject is in the process of grabbing the object, the acceleration of the parallel table on the wrist will be The big and small 'the other two axes of acceleration on the wrist _ can see whether the wrist has a flip, and the accelerometer on the shoulder can know whether the subject has moved 201121525. In addition (4) the distance on the side of the electronic scale The angle of the elbow bending can be calculated by adding the length of the arm.
