2、easy to fall down and have a series of problems that threat the quality of life .In the process of rehabilitation of the patients, the accurate detections and assessments of the balance ability are quite important. At pr

3、esent, the hand assessments are widely used in clinical, according to some scale to score the patients, it is useful, but relies on the subjective judgments of physician and lacks objectivity; furthermore the use of test

4、ing instruments to assess the balance, can obtain the data of gravity center on the static and moving conditions, and then assess the balance ability. The test results on patients are accurate, but are not objective enou

5、gh. This research did the following work so as to improve the defection of the balance detecting equipment: First, the design has a testing platform with three sensors, and uses ATmega128 microcontroller as the main chip

6、, which includes the peripheral circuits with the functions of the low-pass filtering and signal amplification. The system can gain accurate, timely sensor data and calculate the shake Track Data of the gravity center of

7、 the human body with the help of internal procedures in the microcontroller, then pass them through the serial port to the processing software. The aim is to obtain the stable, timely data of gravity center, to analyses

8、and evaluate the body balance accurately and objectively Second, the PC software designed by LabVIEW has timely display interface with the gravity center and the data storage function. And the use of LabVIEW and MATLAB p

9、rogramming technology mixed with Mat files automatically calculates the settling time Ts off-line processing software. Third, owing to the deficiency of the instruments for the detection of body, passive detection is pro

10、posed. The detection platform placed in the moving platform which can provide the incentive on the horizontal direction movement to foot， then to collect the feedback data of body adjustment to the balance, so that it ca
