A recent study aims to determine whether low-frequency electroacupuncture can improve symptoms and nerve function in people with diabetic peripheral neuropathy, offering a potential non-pharmacological treatment option amid ongoing debates about efficacy.
A new randomised trial protocol published by the journal article hosted on Dove Press sets out to test whether low-frequency electroacupuncture can help people with diabetic peripheral neuropathy, a common complication of diabetes that often causes pain, numbness and tingling in the feet and legs. The study is designed to compare active treatment with a sham procedure and to measure not only symptoms but also nerve conduction, quality of life and several blood markers linked to inflammation and nerve repair.
Diabetic peripheral neuropathy affects a large share of people with diabetes over the course of the illness, and the National Institute of Diabetes and Digestive and Kidney Diseases says it can affect up to half of patients. Mayo Clinic notes that, as the condition advances, it can contribute to foot ulcers and infections, underlining why better symptom control matters. Current treatment largely centres on glucose management and medicines for neuropathic pain, but the protocol’s authors argue that long-term drug use can be limited by side effects, leaving room for non-pharmacological approaches.
Electroacupuncture is one such option. Evidence cited in the protocol and in more recent published analyses suggests that it may improve pain and nerve function in diabetic peripheral neuropathy. A systematic review and Bayesian network meta-analysis indexed on PubMed found electroacupuncture to be the most effective acupuncture approach for improving motor nerve conduction velocity, while a multicentre randomised trial published earlier reported reductions in pain and gains in quality of life among people with painful diabetic peripheral neuropathy. Another review of randomised trials, published in the Journal of Traditional Chinese Medicine Science, reached a similar cautious conclusion, saying electroacupuncture may be beneficial but needs stronger confirmation.
The new study, registered on ClinicalTrials.gov, will enrol 92 adults at the First Affiliated Hospital of Zhejiang Chinese Medical University and randomly assign them to active treatment or sham treatment. Participants in the active arm will receive 12 sessions over six weeks at a fixed low frequency of 2 Hz, while the control group will receive superficial needling with a disconnected stimulator that mimics the appearance of real electroacupuncture. The investigators say this design is meant to preserve blinding and separate any genuine physiological effect from expectation alone.
The trial will focus first on a composite response rate and on lower-limb nerve conduction velocity, with secondary measures including pain scores, the Toronto Clinical Scoring System, diabetes-related quality of life and blood levels of nerve growth factor, brain-derived neurotrophic factor, tumour necrosis factor-alpha and interleukin-6. The protocol’s authors say the biomarker work is intended to explore whether any symptom improvement tracks with changes in inflammatory and neurotrophic pathways. They acknowledge, however, that the study is single-centre, cannot fully blind the practitioners delivering the treatment and uses a sham procedure that may not be entirely inert.
If the trial is successful, it could add to a growing but still mixed evidence base for acupuncture-based treatment in diabetic peripheral neuropathy. For now, it is best read as a carefully planned attempt to determine whether a standardised low-frequency electroacupuncture regimen can offer measurable benefit beyond placebo, and whether any such benefit is reflected in objective nerve testing as well as in patients’ day-to-day symptoms.
