[Some new viewpoints on the interpretation of rheograms of the extremities. II. Rheograms of the foot].
1. Taking into consideration the establishments concerning the connection between the sizes of angles measured in the rheogram and gauging made in the first report, rheographic examinations of the foot were performed. In 168 healthy test persons the lower borderline values for the relative pulse volume, the height of the peak, the angle of increase, the angle of the peak and the angular sum of the after-waves were established. The lower borderline values, above which 97.8% of all values in healthy persons are to be expected, are given in a table. 2. The group of the healthy test persons was compared with a group of 137 patients with angiologic diseases. Out of these patients 228 evaluable measurements were the result per parameter. In this case, as in the examination of the shank, could be established that the angular sum of the after-waves as separating parameter showed the largest impact number with 88.3%. 3. The beginning of the pulse-wave at the foot showed an age dependence in the rheographic examination known already from examinations of the pulse curve with other methods. A restricted use of this parameter in practice is possible in unilateral processes.
