Abstract :
A battery-powered posture measurement system has been developed to monitor the topographical features of a scoliotic trunk. The system consists of an electromagnetic measurement system and a microcomputer data acquisition system. The polar coordinates of up to 8 receivers relative to the transmitter can be determined. Laboratory tests showed that the maximum distance error was 0.5 cm and the maximum angle error was 5 degrees in the range of 30 to 47 cm. This system is applied to help adolescents who have scoliosis attain a more balanced posture with the use of feedback preliminary clinical trials were done and showed that the system was able to detect the postural changes
