Effects and Central Mechanism of Electroacupuncture and MRI-navigated rTMS for PSD
Effects and Central Mechanism of Electroacupuncture and MRI-navigated rTMS for PSD: a fMRI-based Single-center, Randomized, Controlled, Assessor-blinded Trial
Introduction:
Post-stroke depression (PSD) is the most common mental complication after stroke and has a serious impact on functional outcomes and quality of life. Antidepressants are the first-line treatment for PSD, but many reported side effects remain. Clinical research and practice guidelines have shown that electro-acupuncture and rTMS have a positive effect on PSD. This trial aims to study the efficacy and safety of electro-acupuncture and a modern MRI-navigated rTMS for PSD and to explore its fMRI-based central mechanism on depression. It is hypothesized that electro-acupuncture and MRI-navigated rTMS treatment improves depressive symptoms, neuro-patho-physiological behaviors, quality of life and central response in PSD.
Methods:
In this randomized, controlled, assessors-blinded trial, sixty-four patients with PSD will be randomly allocated into the experiment group (n=32) or control group(n=32) . The experiment group will receive electro-acupuncture and MRI-navigated rTMS, and the control group will receive MRI-navigated rTMS treatment, in 12-20 sessions over 4 weeks. In addition, ten healthy people for fMRI scanning will be recruited as a healthy control group without any intervention. The primary outcome is the change from baseline in the Hamilton Depression Scale-24 items (HAMD-24) scores at week 4. The primary analysis of central mechanism mainly involves cortical morphology, local spontaneous brain activity, and default mode network (DMN) functional connectivity based on fMRI at 0-wk and 4-wk. Secondary outcomes include the neuro-patho-physiological and quality of life changes in cortical excitability with motor evoked potential test(MEP), National Institutes of Health Stroke Scale(NIHSS), EuroQol Five Dimensions Questionnaire(EQ-5D) Scale, Modified Barthel Index(MBI) Scale and Short Form-Health Scale of Traditional Chinese Medicine(SF-HSTCM). Additional indicators include the Acceptability Questionnaire and Health Economics Evaluation (cost-effectiveness analysis) to assess acceptability and economic practicality of the treatment in study. Outcomes are assessed at baseline and post intervention.
Discussion:
Electro-acupuncture and MRI-navigated rTMS therapy could become an alternative treatment for PSD, and it is expected that this trial will provide reliable clinical evidence and potential effect mechanism for the future use of electro-acupuncture and MRI-navigated rTMS for PSD.

Experimental: Experiment group
electro-acupuncture and MRI-navigated rTMS

Acupoints consist of Neiguan (PC6, bilateral), Shuigou (GV26), Sanyinjiao (SP6, affected side), Yintang (EX-HN3), Shangxing (GV23), Baihui (GV20), and Sishencong (EX-HN1).
Disposable stainless-steel needles (0.25mm× 40 mm)will be used.
After skin disinfection, the acupuncturists will twist and thrust the needle handles to achieve the sensation of achiness, heaviness, and numbness (known as de qi) at all acupoints.
Following needle manipulations, electroacupuncture instruments(SDZ-V) will be used to attached the needle handles at EX-HN3, GV23, GV20 and EX-HN1 with a dilatational wave of 5 ~ 10 Hz and a current intensity of 1 ~ 3 mA depending on the patient's tolerance.
The needles will be removed after 30 minutes except for GV26 without needle retention.
Participants will receive 12-20 electroacupuncture sessions over four weeks at a frequency of 3-5 times per week.
MRI:All MRI scans were taken to acquire high-resolution T1-weighted anatomical images on the 3T MRI Scanner.
Electromyography(EMG):Surface EMG was used to record MEPs from the abductor pollicis brevis for determining RMT of the non-lesioned motor cortex.A single TMS pulse was delivered to the location to identify the RMT,defined as the minimum intensity capable of evoking at least 5 MEPs of >50 μV in 10 consecutive trials.MRI-navigated rTMS:Using BrainSight system,left DLPFC targeting was individualized by reconstructing MRI data into a 3-dimensional brain image for neuro-navigation.
Left DLPFC localization was central middle frontal gyrus,between superior frontal sulcus and middle frontal sulcus based on T1-weighted anatomical images.Focal rTMS was administered using a Magstim Rapid 2 connected to Y125-round coil that was identical.rTMS
was applied at 110% RMT to the left DLPFC.At each session,3000 pulses were applied at 10 Hz with a total of 12-20 rTMS sessions over a 4-week period.
