Abstract
This study describes the effect of Active Corset on the lumbar spine. Active Corset is assist tools used to prevent low back pain. It tightens the waist optimally according to the lumbar load during work. This study aimed to clarify the mechanical effect of tightening of the pelvis on lumbar joints and determine the mechanism leading to reduction of the lumbar load. Moreover, this study examined the phenomena commonly occurring among the subjects with reduced lumbar load by tightening of the pelvis. First, we will present some examples of currently used assist tools and demine the utility of the Active Corset among the various tools used. Next, the mechanism of the Active Corset will be described. Further, we will present a hypothesis about reducing the lumbar load by tightening the pelvis. After describing the change in the joint bending angle on tightening, we will describe reduction of burden from the antigravity torque around the lumbar joint. Finally, we will compare active tightening using Active Corset with tightening using a constant force and describe the advantage of active tightening.
