Abstract
This paper presents an IMU-based wireless wearable system for real-time three-dimensional measurement of spinal deformities in a noninvasive manner. Applications of the proposed system range from diagnosis of spine abnormalities to postural monitoring, on-field as well as in a lab setting. The system is comprised of one wireless and 26 sensor nodes wired along to form a lightweight wearable sensor stripe for superficially attachment above human spine. The nodes size and arrangement is optimized so that each node to approximately track an individual vertebra. All sensors communicate to the main unit through I2C bus in a daisy chain fashion. Spine is modeled as a compound flexible with 26 segments allowing dynamic measurement of three-dimensional spine motion, which is animated and monitored in real-time using dedicated Android application with interactive GUI. The proposed system detects Kyphosis, Lordodis and Scoliosis and calculates the related Cobb angles. It can be integrated in wearable chest harness and is highly suitable for both diagnose spinal deformities in early stages and follow up the progress of the spine.
