About

Diabetic peripheral neuropathy (DPN) is the most common chronic complication of diabetes mellitus that has a considerable impact on quality of life, but there are few effective therapeutic strategies. The aim of this trial is to determine the efficacy and safety of manual acupuncture (MA) versus sham acupuncture (SA) for DPN.

Full description

A total of 118 patients with DPN will be recruited and randomly assigned in a 1:1 ratio to either the MA group or SA group. All patients will receive 24 sessions over 12 weeks. Participants will complete the trial by visiting the research center at month 6 for a follow-up assessment. The primary outcome is peroneal motor nerve conduction velocity (peroneal MNCV) at week 12 compared with baseline. Secondary outcomes include peroneal motor nerve action potential amplitude (peroneal MNAP) and latent period (peroneal MNLP), sural sensory nerve conduction velocity (sural SNCV), action potential amplitude (sural SNAP) and latent period (sural SNLP), fasting plasma glucose (FPG), 2-h postprandial blood glucose (2hPG), glycated hemoglobin (HbAlc) at week 12 compared with baseline, Michigan Neuropathy Screening Instrument (MNSI) score and Diabetes Specific Quality of Life scale (DSQL) at week 12 and month 6 compared with baseline. Safety will be assessed during the whole trial. Masking effectiveness will be assessed by patients.

---

118 participants in 2 patient groups

Manual Acupuncture Group

Experimental group

Description:

Treatment will be performed by licensed acupuncturists who have at least 5 years of experience in acupuncture. All the acupuncturists will be trained how to locate acupoints, puncture, and manipulate needles before trials.

Treatment:

Other: Acupuncture

Sham Acupuncture

Sham Comparator group

Description:

The procedure and duration of treatment in the sham acupuncture group will be identical in the MA group except the needles are blunt tip and there will be no skin penetration and needle manipulation for De qi.
