Primary Outcome Measures:
  • near infrared spectroscopy [ Time Frame: one time ]
    Near infrared (NIR) is measured by spectroscopy on the skin using the DDD probe


Enrollment: 30
Study Start Date: September 2012
Study Completion Date: October 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Diabetic neuropathy
Male participants, type1 diabetic with diabetic neuropathy
Diabetes without neuropathy
Male participants, type1 diabetic without diabetic neuropathy
Non diabetic control
Male participants, control group non diabetic

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.
