A RAPID METHOD FOR SCORING THE GLADSTONE GROUP PALMAR SWEAT TEST.
Abstract
Recently, two methods of measuring palmar sweat which can be used with large groups have been described. The simplest of these is that of Gladstone which is an adaptation of a test developed by Silverman and Powell. The method as described by Gladstone consists of preparing paper in a five per cent tannic acid solution and then coating the subject's fingers with a solution of ferric chloride and acetone. After the fingers dry, they are pressed against the paper for a period of three minutes. This produces a print the darkness of which is a function of the amount of sweat present on the fingers. The present paper deals with the method of scoring these prints. Gladstone scored the prints by passing a light through them and activating a photoelectric cell, the output from which was measured with a microammeter. The score thus obtained is inversely proportional to the darkness of the print. The reliability of this method was found to be .993 for 41 cases. (Author)
