Feasibility of a Low-cost Microcontroller Based Lumbar Flexion-relaxation Phenomenon Monitoring System

Abstract

This paper investigates the potential of using a low-cost microcontroller based system to monitor the lumbar flexion-relaxation phenomenon in the erector spinae muscle. A BITalino microcontroller was interfaced with an electromyography sensor and accelerometers. The data was combined in Matlab. The results indicate that the system is capable of visually demonstrating the presence of the lumbar flexionrelaxation phenomenon.
