Quantitative evaluation of physical activities in stroke patients before and after leaving hospital using a wearable posture changes and gait analysis system: Simultaneous comparison examination with Life-Space Assessment

It is important to evaluate quantitatively physical activity and gait state for stroke patients before and after leaving hospital. In this study, using a wearable posture changes and gait analysis system, measurements of the activities of daily living for patients were carried out on 5 occasions: in hospital, after leaving hospital, and 1, 2 and 3 months after leaving hospital. As a result, detailed information has been measured, as the ratio of standing and walking, the frequency of posture change, the steps, the frequency of gait, the moving distance during stance phase of a paralyzed side, and the average walking speed. Moreover, the relevance of the evaluation index of this system and Life-Space Assessment, LSA was checked from the result of correlation analysis. And, about each measurement time, I revealed what physical activity of the patient will affect the range of activity. Therefore, this technique was useful to physical activity and gait state for stroke patients before and after leaving hospital.
