The Effect of Acupuncture Therapy on Cognitive Function in Post-COVID-19 Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Condition(s) studied

Investigational drug(s) / intervention(s)

Acupuncture: Participants will be alternatively acupunctured on two set of acupoints . The first set of acupuncture points incudes Baihui (GV20), bilateral Shenmen (HT7), bilateral Neiguan (PC6), Qihai (CV6), Guanyuan (CV4), bilateral Zusanli (ST36), bilateral Sanyinjiao (SP6). The second set of acupoints consist of Sishenchong (EX-HN1), bilateral Ganshu (BL18), bilateral Pishu (BL20), bilateral Shenshu (BL23), bilateral Taixi (KI3).The treatment consists of 24 sessions of 30 minutes, given within eight weeks (three sessions per week). A set of acupoints is acupunctured each treatment session.

Sham acupuncture: Nonpenetrating acupuncture on non-acupoints will be performed using Park sham acupuncture device (0.25 mm in diameter and 40 mm in length, Hwatuo, Suzhou, China) for participants. Two sets of non-acupoints will be alternatively acupunctured. The first set of sham acupoints includes bilateral non-acupoint 1, bilateral non-acupoint 2, non-acupoint 3, non-acupoint 4, bilateral non-acupoint 5, bilateral non-acupoint 6. The second set consists of bilateral non-acupoint 7, bilateral non-acupoint 8, bilateral non-acupoint 9, bilateral non-acupoint 10. The treatment consists of 24 sessions of 30 minutes, given within eight weeks (three sessions per week). A set of non-acupoints will be acupunctured each treatment session.

Study summary

Background of study:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a common sequela after SARS-CoV-2 infection(COVID-19). Cognitive dysfunction is one of the most common debilitating symptoms in ME/CFS. Currently, standardized therapy for ME/CFS has not been established. Some treatments, such as cognitive behavioral therapy (CBT) and graded exercise therapy (GET), mainly exert effects on physical symptoms, whereas the influence on cognitive problems is not significant. Acupuncture is an important complementary and alternative therapy for ME/CFS. However, However, research focused on the impact of acupuncture on cognitive functions in ME/CFS is rare. Additionally, no study has evaluated the efficacy and mechanism of acupuncture treatment in improving cognitive functions for post-COVID-19 ME/CFS.

Objective of the study:

The first objective of this study is to assess the efficacy of acupuncture treatment in improving cognitive function for post-COVID-19 ME/CFS. The second objective is to explore whether acupuncture improves cognitive ability in patients with post-COVID-19 ME/CFS through modulating hippocampal connectivity and metabolites using multimodal magnetic resonance imaging(MRI).

Study design:

A prospective, three-armed, randomized controlled trial with resting-state functional MRI(rs-fMRI) and magnetic resonance spectroscopy(MRS). Adults with post-COVID-19 ME/CFS will be randomly assigned to acupuncture, sham acupuncture, or waitlist control group in a 1:1:1 ratio, receiving 8-week intervention or waiting. Cognitive functions and resting-state functional connectivity(RSFC) and the levels of metabolites for each hippocampus will be examined at baseline and 8th week.

Study population:

Patients fulfilling 2015 National Academy of Medicine (NAM) criteria for ME/CFS following COVID-19.

Eligibility

Primary outcome measure(s)

• Change of Symbol Digit Modality Test score from baseline to the end of 8 weeks — Baseline and 8 weeks
  Symbol Digit Modality Test assesses attention through measuring the number of correct responses within 90 seconds. The minimum score is 0, and the maximum score is 110. Higher score indicates better attention.
