Head Posture Analysis using sEMG Signal

The purpose of this study was to determine the muscle activity of upper trapezius muscle of different head posture at standing and sitting positions by using surface electromyography (sEMG) signals. This tool may be a non-invasive technique that enables the analysis of muscle activity. Human's head posture is significant part of human body and have a big role to analyze posture of human body. During this approach surface electrodes are employed to record surface electromyography (sEMG) signals of head posture at different angles. It is discovered that the muscle action of upper trapezius at both standing and sitting position is higher at 60 degree of head pose, whereas it's lower just in case of zero degree that may be a neutral posture of head. It was also found that the muscle activity at standing position is higher than that of sitting position and in the result right trapezius muscle is more activate in standing position than the sitting position. It was also investigated that the muscle activity in standing is higher than that of sitting position. It is suggested that the muscle activity of head posture is lower in neutral position of head.
