A randomized clinical trial of the effectiveness of photon stimulation on pain, sensation, and quality of life in patients with diabetic peripheral neuropathy.

Context: Peripheral neuropathy is one of the most common complications of diabetes.

Objectives: The purpose of this study was to evaluate the effects of photon stimulation on pain intensity, pain relief, pain qualities, sensation and quality of life (QOL) in patients with painful diabetic peripheral neuropathy.

Methods: In this randomized, placebo-controlled trial, patients were assigned to receive either four photon stimulations (n=63) or four placebo (n=58) treatments.
