Knee bend ergometer with counter

摘要

The spacing between the measurement points alters by the bending or stretching of the knee. A measurement sensor (3, 6, 8) measures the alteration of the distance between the two measurement points caused by the bending and stretching of the knee. It also measures the speed at which the distance alteration occurs. Connected to the measurement device is an evaluation circuit which stores a weight value related to the test person. It assesses the work and/or power effected by the test person or a value correlated to it by connecting the weight value with the measurement value(s) supplied by the measurement device.
