[Quantitative evaluation of perspiration with equipment for continuous recording of local perspiration volume (II): Hyperhidrosis and hypohidrosis (or anhidrosis)].

To objectively evaluate perspiration volume, we tried to measure the perspiration volume from 6 cases of hyperhidrosis and 4 cases of hypo-(or an-) hidrosis using recently developed equipment for continuous recording of local perspiration volume. Patients with hyperhidrosis were loaded with various factors to possibly influence the perspiration volume, and the effects were compared. The results revealed: 1) The measurement of local perspiration volume with this equipment provides objective data useful for the diagnosis of hyperhidrosis and hypo-(or an-) hidrosis and for the judgement of its grade; 2) in case of palmar hyperhidrosis, mental stimuli most strongly induced perspiration; and 3) the responses to mental arithmetic or hand grasping and the base-line stable time are reliable parameters for measurement of perspiration volume.
