[The Kiel arthrograph--an instrument for recording active and passive shoulder joint mobility].
The authors describe a new method for measuring the flexibility of the shoulder. They have designed a device consisting of two electrical goniometers to measure the horizontal and the vertical position of the humerus. A computer registers these signals, calculates the region of mobility as a sperical segment centered to the shoulder joint (caput humeri). This region is displayed in a map, called arthrogram. Slightly modified, the arthrograph measures the rotation of the humerus and depicts the rotation angle into the map, at the site of the measurement. First results are reported. The procedure is reproducible with an error less than 5 degrees. Arthrograms of sound persons are compared to those of different pathological symptoms. Arthrograms show more information than single angular values. They can be viewed easily, e.g. to control the success of a treatment.
