Fracture protective efficacy by bone density elevation and the quantity of muscle increase due to the stimulation of concussion and vibration

当人们长时间站立时，他们会通过不自觉地将身体的重心在左右之间移动来防止疲劳。从某种意义上说，他们是在进行温和的全身锻炼。站在摇晃的盘子上比站在静止的盘子上需要更合适的全身锻炼。在本研究中，我们观察到，在骨矿密度(BMD)下降的小鼠模型上施加震动刺激可以防止股骨强度下降，尽管预防程度因部位而异。由震动刺激引发的全身运动可能代表着一种新的物理疗法，不仅适用于老年人，也适用于年轻人，用于预防骨折和促进健康。

When people stand for a long time, they prevent becoming tired by unconsciously shifting the center of mass of the body between the right and left. In a sense, they are performing mild whole body exercise. Standing still on a shaking plate invokes more appropriate whole body exercise than that when standing on a motionless plate. In the present study, we observed that shaking stimuli applied to a mouse model of declining bone mineral density (BMD) prevented femoral bone strength from decreasing, although the degree of prevention differed from site to site. Whole body exercise provoked by shaking stimuli may represent a novel physical therapy in bone fracture prevention and health promotion not only in the elderly, but also in young people.
