title: [Reliability of the evaluation of the active sweat gland density on the dorsum of the foot using the silastic impression mold technique].
abstract: The evaluation of the density of the active sweat gland on the dorsum of the foot induced by iontophoresis of 1% pilocarpine was made repeatedly using the silastic impression mold technique in 83 subjects (52 normal volunteers: 24 subjects younger than 50 years of age and 28 subjects 50 years of age or older, 20 men and 32 women: 20 diabetic patients and 11 patients with other neurological disorders), from 12 to 82 years of age, and the reliability of such evaluation was assessed. After 8 to 14 days following the first evaluation, the second one was performed. The reliability was expressed as an intra-class correlation. The intra-class correlation was greater in the subjects 50 years of age or older (0.909) than in the subjects younger than 50 years of age (0.653). It was similar between males (0.921) and females (0.803). On the other hand, it was less in diabetic patients (0.543) than in the normal volunteers (0.857) and patients with other neurological disorders (0.809). The silastic impression mold technique is widely applicable in evaluating the sweat gland function. However, it should be kept in mind that the reliability is variable among the groups defined clinically and that it is low in the diabetic patients.
