Painful Diabetic Neuropathy Clinical Trial
Official title:
The Therapeutic Effect of Low-intensity Focused Ultrasound on Painful Diabetic Peripheral Neuropathy
Diabetic painful peripheral neuropathy (DPN) constitutes a serious threat to the outcomes of patients with diabetes. Yet, the treatments for targeting the underlying nerve damage and relieving pain are limited. The low-intensity focused ultrasound (LIFU) has been demonstrated to regulate neuronal activity without any concomitant tissue damage. Studies in animal models have shown that LIFU could protect nerve cells against inflammation and oxidative stress, as well as stimulate neurotrophic factor production. In humans, LIFU has been reported to be effective in relieving peripheral neurogenic pain caused by carpal tunnel syndrome and chemotherapy drugs. Thus, we aim to design a randomized controlled double-blind study by using LIFU. The primary endpoint is the patient's pain score (NRS), and the secondary endpoints include Neuropathy Symptom Score (NSS) and Neuropathy Deficit Score (NDS). Through this study, we anticipate establishing a new method for managing painful DPN.
