Experimental Development of Lumbar Supporter and its Evaluation by EMG
In this study, we attempted to produce experimentally a posture correction wear for prevention of 'low back pain'. Then physiological response (i.e. muscular activity and physical energy consumption) and psychological response (i.e.sensory evaluation) were measured when subjects walked on the treadmill wearing the posture correction wear or a commercial lumbar supporter. Fromthe result, the posture correction wear was evaluated ’easy to walk’ in psychological evaluation. It was also found that the posture correction wear gave low constraint on walking, because the muscular activity related to a behavior of coxa was lower when subjects wore the posture correction wear.
