本研究开发并评估了一种简单、廉价、安全的筛查试验，用于评估老年人跌倒风险。 受试者坐在椅子上（臀部和膝盖呈90度），脚放在力传感器上，尽可能用力地站立。 站了五秒钟后，他们以最快的速度坐了下来。 根据计算机收集的数据计算站立和坐姿的力变化率（dF/dT）。 一组nonfallers（n = 23，年龄= 23至72岁）和一组fallers（n = 22，年龄= 63至92岁）进行了研究。 非跌倒者站立时的dF/dT从4kg.sec ~（-1）·kg ~（-1）线性下降到2.5kg.sec ~（-1）·kg ~（-1）。 跌倒者的数值从3kg.sec-1.kg-1线性降低至0.1kg.sec-1.kg-1。 在两组中，坐位的dF/dT不依赖于年龄。 跌倒者的dF/dT比非跌倒者低（分别为1.3 +/- .6kg.sec-1.kg-1和2.3 +/- .01kg.sec-1.kg-1）。 22个跌落者中有17个通过降低的dF/dT和降低的过冲力（kg）来识别。
This study developed and evaluated a simple, inexpensive, and safe screening test for assessment of falling risk in elderly persons. Subjects sat in chairs (hips and knees at 90-degrees) with their feet over a force transducer and stood as forcefully as possible. After standing for five seconds, they sat as fast as possible. The rate of change in force (dF/dT) for standing and sitting were calculated from data collected by computer. A group of nonfallers (n = 23, age = 23 to 72 years) and a group of fallers (n = 22, age = 63 to 92 years) were studied. Nonfallers' dF/dT for standing decreased linearly from 4kg.sec-1.kg-1 to 2.5kg.sec-1.kg-1. Values in fallers decreased linearly from 3kg.sec-1.kg-1 to 0.1kg.sec-1.kg-1. The dF/dT for sitting was not dependent on age in either group. Fallers had lower dF/dT than nonfallers (1.3 +/- .6kg.sec-1.kg-1 and 2.3 +/- .01kg.sec-1.kg-1, respectively). Seventeen of 22 fallers were identified by a reduced dF/dT and reduced overshoot force (kg).
