Details and patient eligibility

About

The Sham Operation Group was used as control, the patients were assessed with the Digital Rating Scale (NRS) , the quality of life-related scale (Euro Qol) , clinical outcome measures: physician's overall impression of changes in pain (CGIC) and patient's overall impression change scale (PGIC) , skin temperature measurement, toe Oxygenation measurement, and anxiety and depression scores (Gad-7, Phq-9) , objective: to evaluate the efficacy and safety of high voltage pulsed radiofrequency in the treatment of peripheral neuralgia in patients with diabetic foot.
