Remotely analyze spine angle in rehabilitation after spine surgery using acceleration and gyro sensors

The purpose of this study was to determine range of motion values of lumbar spine in rehabilitation procedure after surgery, using wearable wireless sensors. In this paper, we present a method for determining the mobility of the spinal column using a network of sensors. The sensors consist of accelerometers and gyroscopes, and mutual communication is accomplished using a I2C bus. The main sensor node collects data from all the sensors and sends them to a computer using Bluetooth communication. The collected data is then filtered and converted to the values of the angles that are of interest to quantify the movement.
