dc.description.abstract | This research is aimed to design a new assessment and training system of human standing balance. In addition to hardware design and production, we have also made the assessment software which could be used together with the hardware. In terms of system features, the hardware offers the individual the chance to actively control and interact with the platform. As for the assessment software, we have designed numerous assessment items and parameters on the basis of tilt.
In order to examine the discriminating power of the newly developed system, we have looked at two groups whose balance control had been known different, stroke patients (n=3) and normal young adults (n=3); then compared the assessment result in system parameters (n=36) of these two groups. It was found that most parameters showed a statistically significant difference (p<0.000). Meanwhile, the stroke patients have also done the Berg’s Functional Balance Test (total score) and one-foot standing experiment (second), which were analyzed by Pearson correlation tests together with system parameters. The result showed that 3 (3/36) system parameters was significantly related to Berg’s Functional Balance Test, while 4 (4/36) system parameters were significantly related to the one-foot standing experiment result. After the correlation result was analyzed, we found that the further backward the stroke patients could move their body weight on the system, the better they were at balance control. With the construction of the parameter norms and the completion of studying balance training advantages, this system is expected to become a new aid for the clinical assessment and training of standing.
