One reason elderly people tend to fall more often that others is a physiological decline in their ability to maintain their balance. To understand a human's capacity for maintaining balance, we designed a convenient and low-cost wearable center of pressure (COP) device that can measure the dynamic COP of a person who is walking. The introduced analysis algorithms allow observation of the properties of human balance, and we hope to improve fall detection and prevention in the elderly. Method In this study, we present a custom made measurement device that contains three pressure sensors attached to an insole. When the subject stands on the insoles, plantar pressure of the subject can be measured. Spatial plantar pressure distribution is an important and useful measurement for gait analysis1. In order to assure correct positioning of the sensors, the exact positions were determined using blueprints of the feet for each individual subject. The COP computations were performed for each foot individually2, with the goal of computing the global dynamics of the COP. To calibrate and assess the functioning of the device, weights were placed on each sensor, one at a time, to observe changes in the COP. After calibration, subjects were asked to walk on their insoles to determine COP displacement during walking. Results & Discussion After repeated testing, the concept of using pressure sensors in the insoles can be demonstrated. Figure 1 shows the three different time intervals that are divided by the timing that we put on each weight. The position of the COP is getting close to the weight-added sensor. The time between 0 to 25 seconds represents stepping (Figure 2). When the left foot goes up, the right foot goes down, and vice versa. Leaning forward and backward is shown between 30 to 45 seconds, so both left and right go up or down simultaneously. In the future, these dynamic COP insoles should be verified with commercial products, such as the Advanced Mechanical Technology Incorporation (AMTI) force plate for the accuracy of the device. pubtype: Academic Journal doctype: abstract proceedings research Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
