Brief summary

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

Detailed description

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.
