Abstract

A battery-powered electromagnetic (EM) system has been developed to measure topographical features of the trunks of patients with scoliosis. The system includes an EM measurement system and a data acquisition system. The system resolution and accuracy are 0.25 cm in the range of 15-30 cm. The entire system can be carried by scoliotic patients during daily activities. The dimensions of the system are 10 cm×14 cm×4 cm and its weight is 100 g. A patient´s posture can be evaluated in real time so that appropriate feedback can be provided to correct his/her posture
