Evaluation of low back pain factors by measuring the planter pressure.

在这项研究中，我们假设种植压力可以估计背部肌肉的应力。首先，我们研究了植入器压力分布与背部肌肉应力的关系。随着腰背部倾斜角的增加，足底压力的趾跟比增大，腰背肌的肌电也随之增大。接下来，我们创建了鞋垫类型的播种机压力数据记录器，并测量了受试者在几个小时内的播种机压力。我们可以从播种机的压力来估计受试者的运动。我们还发现，长时间站立是导致长期站立工人腰背痛的原因之一。

In this study, we hypothesized that the planter pressure could estimate the stress of the back muscles. First, we investigated the relationship between the planter pressure distribution and the back muscles stress. According to the tilt angle of the low back, the toe/heel ratio of planter pressure was increased and also increased electro myogram of the low back muscles. Next, we created the insole typed planter pressure data loggers and measured planter pressure of the subjects during several hours. We could estimate the motion of the subjects from the planter pressure. And also we revealed that the longer standing period caused a reason of low back pain among long standing workers.
