A wireless surface electromyography system design for lumbar disc herniated patients

Lumbar disc herniation is a quite common disease in community. There are many studies those prove the relationship between paraspinal muscles and lumbar disc herniation. In our study we aimed to design a wireless surface electromyography system that helps to track regional muscular activities of lumbar disc herniated patients easily. Finally, we aim to complete this study as an alternative diagnosis technique of lumbar disc herniation. Overall system consists of six major parts. The collected signals are preamplified, filtered and digitized. The digital data is collected with a low-power microcontroller and transferred to the computer via Bluetooth module. The transferred data are evaluated and further signal processing techniques are realized with MATLAB.
