About

Diabetic Peripheral Neuropathy (DPN) is one of the most common chronic complications of diabetes mellitus, which mainly manifests symmetric pain, numbness, ankylosis, or with abdominal distension, abnormal sweating, and accompanied by glove-sock-like hyperalgesia or loss of sensation as the main symptom, which seriously affects the quality of life of patients. Although drug treatment has some effect, from the overall long-term perspective, long-term medication is easy to produce drug dependence, and often easy to cause ataxia, blurred vision, constipation, diplopia, nausea and other adverse drug reactions. Electroacupuncture treatment for DPN has certain advantages, with clear efficacy and no toxic side effects, and is being increasingly recognised by the public and professionals. The study is designed to observe the therapeutic effect and safety of electroacupuncture (EA) in the treatment of DPN.

Full description

A total of 104 subjects with DPN who meet the inclusion criteria will be included in the study. Subjects will be classified as mild, moderate and severe in terms of severity by using the toronto clinical scoring system（TCSS）, and subsequently randomised into the EA group and the waiting list group by using a central randomisation system. The indexes of main outcome evaluation are: sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity (MNCV) of the tibial and peroneal nerves of the lower extremities. The indexes of secondary outcome evaluation are: 1) Overall clinical effectiveness rate; 2) TCSS score; 3) Chinese medicine symptom score; 4) patient's global impression of change (PGIC); 5) regional temperature test; and 6) laboratory tests (glycosylated haemoglobin, fasting blood glucose, and postprandial 2h blood glucose). This study will evaluate the effectiveness of EA in treating DPN and assess the difference in the efficacy of EA in treating patients with DPN of different severity, as well as explore the feasibility of regional temperature as an indicator for assessing the efficacy of DPN. And based on the results, a standardised, effective and convenient EA treatment protocol will be established for promotion.
