WIRELESS SURFACE ELECTROMYOGRAPHY DEVICE DESIGN FOR LUMBAR DISC HERNIATED PATIENTS

Bel fıtıklı hastaların bölgesel kas faaliyetlerinin takibi amacıyla portatif ve kablosuz bir yüzey elektromiyografi cihazı geliştirilmiştir. Önceki çalışmalar paraspinal kas aktiviteleri ile bel fıtığı arasında ilişki olduğunu göstermektedir. Bu çalışmalar bel fıtıklı hastaların kas faaliyetlerini takip amacıyla yeni bir kablosuz yüzey elektromiyografi cihazı yapmaya teşvik etmiştir. Böyle kablosuz cihazın kullanımı bel fıtıklı hastaların kas akitivitelerini daha kolay takibini sağlayacaktır. Genel olarak sistem yeni bir yaklaşım ile bel fıtığı teşhisinin yapılabilmesinin önünü açabilecektir.Geliştirilen sistem kuvvetlendirme, filtreleme, analog-dijital dönüştürme ve kablosuz haberleşme olmak üzere dört ana kısımdan oluşmaktadır. Elde edilen cihaz ile bilgisayar arasındaki haberleşme için Bluetooth teknolojisi kullanılmıştır. Cihaz MATLAB yazılımı üzerinden kontrol edilebilmektedir ve doğrudan bilgisayar ortamına aktarılmaktadır. Geliştirilen sistem ile elde edilen yüzey elektromiyografi sinyalleri üzerinde MATLAB programıyla sinyal işleme de yapılmıştır

A portable and wireless surface electromyography device was developed for tracking the regional muscular activities of lumbar disc herniated patients. Previous studies showed that there is relation between paraspinal muscular activities and lumbar disc herniation. These studies encouraged us to develop a novel wireless surface electromyography device to follow muscular activities of lumbar disc herniated patients. Using such kind of wireless system in lumbar disc herniation studies leads to follow muscular activities practically. The overall system would lead to make diagnosis of lumbar disc herniation with a novel approach. The developed system consists of four major stages; amplification, filtering, A/D conversion, and the wireless communication stages. Bluetooth technology is chosen for communication between the proposed device and the computer. The designed device can be fully controlled within MATLAB software, and measured data can be directly streamed to computer environment. As a demonstration of the developed system, we also did certain signal processing operations in MATLAB by using measured surface electromyography signals.
