| Popis: | 96 Background: Balance dysfunction in older persons often causes them suffering fall accident. Each year, high insurance cost was found in medical care for elderly fall. Anticipatory balance training is a useful method that is gradually adopted in rehabilitation clinic; especially for aging person. Therefore, developing a system based on anticipatory balance theory may provide a useful selection for clinicians or older persons in balance rehabilitation. Purpose: Study purpose was to develop a system that can be used to assess and train balance function for older persons. Method: In order to assess and train elderly balance function, present system developed a single-axis force plate. Four load cells were installed beneath the plate surface. When subject stood on it, center of force (COF) during standing can be detected. System mainly contained two functional modules; assessment module and rehabilitation module. These two modules can simultaneously executed by using network communication technique (TCP/IP settings). In assessment module, it provides function in measuring COF changes. In rehabilitation module, it provided video-game based rehabilitation concept in balance training. To accomplish this system, several necessary equipment and techniques were required. That included signal processing, data acquisition, software programming (using LabVIEW and Visual C++). To achieve anticipatory balance training effect, we selected a video game that fitted training requirement in visual alert and body balance control. In order to validate system function and performance, we used one adult and one older person; to test the system. Average sway velocity, total sway distance and sway range were used to examine the difference of balance capability between two tested subjects. System advantage included that basing on anticipatory balance control theory and using video-game based rehabilitation technique. Results and Discussion: A visual anticipatory training and assessment system with useful software was successfully developed. The system parameters allowed investigator to differentiate balance in older persons. Comparing with young adult, elderly showed had larger COF distance and velocity (COFd = 75.0%, COFxd = 79.1%, COFxd = 65.7%, COFv = 67.2%, COFxv = 58.8%, COFyv = 108.7%), but had lower training performance (Time = 17.8%，Score = -45.4%). Conclusion: Present study developed a quantitative and valid system for training and evaluating elderly balance capability. In the future, the study need more subject to examine and investigate balance difference between elderly and adult groups. |
