NIR- and Multifrequent Impedance Spectroscopy on the Skin in Type 1 Diabetes

NIR (Near Infrared)- Spectroscopy and Multifrequent Impedance Spectroscopy on the Skin to Detection of Sensory and Autonomic Neuropathy Among Patients With Type 1 Diabetes

The aim of the study is to examine the suitability to detect diabetic neuropathy using NIR and impedance.

The aim of the study is to examine how suitable a hand-held measuring probe (DDD-probe) using NIR (near infrared light) as well as impedance (conductivity), is to detect early signs of diabetic neuropathy.

The DDD-probe is put directly on the skin and is measuring by the use of light and impedance.

Inclusion Criteria:

• men with type 1 diabetes (WHO criteria)
• age 35-50 years
• duration of diabetes > 10 years

Exclusion Criteria:

• P-creatinine> 120 micromol/l
• other acute or chronic disease, or type of treatment that makes the patient unsuitable to participate, valuated by the investigator
• non intact skin on the measuring spots
• the patient is unable to understand the informed consent
