Abstract:
Monitoring equipment and systems for older people and those with health problems are usually based on measuring vital signs and monitoring behavior and have the problems of invasion of privacy and difficulty with operation. We have developed a floor mat-type walking measurement device with a pressure sensor to determine natural walking conditions in daily life. The equipment consisted of a grid of eight pressure sensors, each perpendicular and parallel to the direction of walking. Although walking speed was calculated using the least-squares method, we did not show its relevance to walking assessments. In this study, to confirm the usefulness of walking assessments with this equipment, we simulated visual and motion limitations due to weight loading on the trunk and upper and lower limbs and compared the results with the timed up and go test used in rehabilitation assessments. In addition to the conventional least-squares analysis using programming, we directly calculated walking speed by manually judging footprints and suggested key points in the calculation of walking speed. We analyzed data from the timed up and go test, various movement restrictions using a floor mat-type sensor device, and normal walking with no movement restrictions. Four requirements were found to determine the calculation of walking speed, suggesting the usefulness of this device.
