摘要
A device and a method for the recording, presentation and automatic classification of biomechanical load variables measured on a freely moving test person during a work shift. The invention consists of a series of electronic sensors and a series of measuring and storage electronics for recording the movement of a person at a work site. The measuring and storage electronics include at least two sensors and at least one gyroscope. The method for recording a person at a work site includes measuring a set of body angles over a period of time, and measuring the ground reaction force in the region of the sole of a test person's foot. The next steps involve determining the threshold values for the identification of postures, and comparing of the threshold values determined with the measured body angles to identify motion patterns. Next, the expected total ground reaction force is calculated and then subtracted from the measured total ground reaction force measured to determine externally exerted forces. Next, the process involves identifying the motion patterns and the output of load profiles. After deriving these measurements, the process involves deriving the acceleration and velocity component of the measured body angles and transforming them into individual joint forces and joint moments while taking account of the measured ground reaction force. The final step includes deriving a disc comparison force and presenting the time characteristic of the disk compression force as a load indication.
