Non-specific low back pain (LBP) symptom has been one of the most common work-related musculoskeletal problems, but reliable assessment in clinical settings often faces difficulties due to the lack of clear tissue damage or injury pathways. In this study, a new method of identifying the existence of non-specific LBP using simple evaluation of myoelectric muscle activities (EMG) has been tested to develop a reliable diagnosis method. Twenty participants who had non-specific LBP and nineteen healthy participants were recruited, and participated in a laboratory experiment. Surface EMG signals were recorded from the L2, L4 lumbar elector spinae muscles and external oblique, and rectus abdominis during approximately 2 min walking on a treadmill at a normal speed. Normalized amplitude of EMG signals were compared between the two groups. In results, it was found that the standard deviation and the maximum value of the normalized EMG of the L2 level muscles were significantly greater (p<0.05) for healthy group than for symptomatic participants. This result implies that the non-specific LBP patients could be identified by comparing the peak EMG of low back muscles with that of healthy individuals or possibly by calculating the ratio between the mean and maximum EMG values within symptomatic individual.
