| Outline of Final Research Achievements |
We researched the activities of back muscles at various posture using electromyography. The 30 healthy males were measured at upright standing, slump standing, upright sitting and slump sitting. In each posture, the subjects kept at trunk anterior inclination 0 to 60°at every 10 degrees.Result,the activities of muscle were significantly greater in standing than in sitting. The activities of muscle were increased with increasing anterior inclination. But, in sitting, the activities of back muscles did not change in the early stages of anterior inclination.Especially, in slump sitting were low. In standing, the activities of back muscles were required to a deep anterior inclination. From the above thing, when the hyper activities of back muscles in the early anterior inclination in sitting existed, the probability of a myofascial lumbago was suggested. When the slump sitting keeps on, which is what is called a wrong position suggested the risk of the onset of a lumbago by a myoatrophy.
