Conditions studied: Diabetic Peripheral Neuropathy

In brief

A study to demonstrate the effectiveness of PEMF treatment compared to sham treatment in changing Vibration Perception Threshold (VPT) and Thermal Sensory (QST) in patients with diabetic peripheral neuropathy (DPN) when treatment is administered twice daily through 120-day period.
