Surface electromyography (SEMG) has been frequently used in ergonomics and kinesiology research to assess the amount of physical efforts of skeletal muscles and resultant biomechanical stresses on body joints. The use of surface EMG as a diagnostic method in non-laboratory settings, however, has been limited due to its sensitivity to noises and difficulty in detecting signals from deep muscles. The objective of this study was to determine EMG variables and data collection methods that could identify changes in the spinal stability after pain-free 10-min static stooping. Twenty two subjects conducted simple physical tasks before and immediately after 10-min stooping, and their EMG variables were compared between pre- and post-stooping. In results, mean normalized amplitude of agonist muscles did not vary significantly after stooping, but the amplitude of antagonist muscles decreased after stooping. Decrements in the antagonist muscle activity were significant for flank and isometric back extension exercises (p<0.05). Findings of this study suggest the possibility of using surface EMG in the evaluation of spinal stability and low back health status in simple exercise postures. Changes in the amplitude of antagonist muscles may be indicative of changes in the spinal stability, and the sensitivity of the indicator can be improved, if measured in flank or back extension exercises where required moment to maintain a posture is primarily generated from the agonist muscles.
