Methodological issues of the central mechanism of two classic acupuncture manipulations based on fNIRS: suggestions for a pilot study. Front Hum Neurosci 2022; 16:1103872. [PMID: 36911106 PMCID: PMC9999014 DOI: 10.3389/fnhum.2022.1103872] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 12/19/2022] [Indexed: 03/14/2023] Open
Abstract
Background: Acupuncture reinforcing-reducing manipulation (ARRM) is a necessary procedure of traditional Chinese acupuncture and an essential factor affecting the therapeutic effect of acupuncture. Shaoshanhuo reinforcing method (SSH) and Toutianliang reducing method (TTL) are the most representative ARRMs. They integrate six single ARRMs and pose distinguished therapeutic effects of acupuncture. However, due to the complexity, diversity, and variation, investigating the mechanism of these two classic manipulations is insufficient. The neuroimaging technique is an important method to explore the central mechanism of SSH and TTL. This study attempted to design a randomized crossover trial based on functional near-infrared spectroscopy (fNIRS) to explore the mechanism of SSH and TTL, meanwhile, provide valuable methodological references for future studies. Methods: A total of 30 healthy subjects were finally included and analyzed in this study. fNIRS examination was performed to record the neural responses during the two most representative ARRMs. The cortical activation and the inter-network functional connectivity (FC) were explored. Results: The results found that SSH and TTL could elicit significant cerebral responses, respectively, but there was no difference between them. Conclusion: Neuroimaging techniques with a higher spatiotemporal resolution, combinations of therapeutic effects, and strict quality control are important to neuroimaging studies on SSH and TTL.

Functional Connectivity Modulation by Acupuncture in Patients with Bell's Palsy. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:5928758. [PMID: 27293461 PMCID: PMC4880700 DOI: 10.1155/2016/5928758] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2015] [Accepted: 04/19/2016] [Indexed: 11/17/2022]
Abstract
Bell's palsy (BP), an acute unilateral facial paralysis, is frequently treated with acupuncture in many countries. However, the mechanism of treatment is not clear so far. In order to explore the potential mechanism, 22 healthy volunteers and 17 BP patients with different clinical duration were recruited. The resting-state functional magnetic resonance imaging scans were conducted before and after acupuncture at LI4 (Hegu), respectively. By comparing BP-induced functional connectivity (FC) changes with acupuncture-induced FC changes in the patients, the abnormal increased FC that could be reduced by acupuncture was selected. The FC strength of the selected FC at various stages was analyzed subsequently. Our results show that FC modulation of acupuncture is specific and consistent with the tendency of recovery. Therefore, we propose that FC modulation by acupuncture may be beneficial to recovery from the disease.

The Status of the Quality Control in Acupuncture-Neuroimaging Studies. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:3685785. [PMID: 27242911 PMCID: PMC4875991 DOI: 10.1155/2016/3685785] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/19/2015] [Revised: 03/03/2016] [Accepted: 03/27/2016] [Indexed: 12/31/2022]
Abstract
Using neuroimaging techniques to explore the central mechanism of acupuncture gains increasing attention, but the quality control of acupuncture-neuroimaging study remains to be improved. We searched the PubMed Database during 1995 to 2014. The original English articles with neuroimaging scan performed on human beings were included. The data involved quality control including the author, sample size, characteristics of the participant, neuroimaging technology, and acupuncture intervention were extracted and analyzed. The rigorous inclusion and exclusion criteria are important guaranty for the participants' homogeneity. The standard operation process of acupuncture and the stricter requirement for acupuncturist play significant role in quality control. More attention should be paid to the quality control in future studies to improve the reproducibility and reliability of the acupuncture-neuroimaging studies.

Abstract
INTRODUCTION Trials of acupuncture for the treatment of depression have produced mixed results. We examined the effectiveness of laser acupuncture compared with placebo acupuncture for the treatment of major depression. METHODS A randomised, double blinded, placebo controlled trial was conducted in Sydney, Australia. Participants aged 18-50 years with DSM-IV major depressive disorder were eligible to join the study. Forty-seven participants were randomised to receive laser acupuncture or placebo laser at acupoints LR14, CV14, LR8, HT7 and KI3. The intervention was administered twice a week for 4 weeks and once a week for another four weeks, for a total of 12 sessions. The primary outcome assessed the change in severity of depression using the Hamilton-Depression Rating Scale (HAM-D), and secondary outcomes assessed the change in severity of depression using the Quick Inventory for Depression-Self Reporting (QID-SR), the Quick Inventory for Depression-Clinician (QIDS-CL), with outcomes assessed at eight weeks. The treatment response (greater than 50% improvement in HAM-D) and remission (HAM-D<8) were analysed. RESULTS At eight weeks participants showed greater improvement in the active laser group on the primary and clinician-rated secondary outcome measures (HAM-D (mean 9.28 (SD 6.55) vs. mean 14.14 (SD 4.78 p<0.001); QIDS-CL (mean 8.12 (SD 6.61 versus 12.68 (mean SD 3.77)) p<0.001). The self-report QIDS-SR scores improved in both groups but did not differ significantly between the groups. In the active laser group, QIDS-SR scores remained significantly lower than baseline at 3 months follow-up. Response rates (active laser, placebo laser) on ITT (intention to treat) analyses were 72.0% and 18.2% (p<0.001), respectively. Remission rates on ITT analyses (active laser, placebo laser) were 56.0% and 4.5% (p<0.001). Transient fatigue was the only adverse effect reported. LIMITATIONS There was no follow-up for the placebo group at one and 3 months. CONCLUSION Laser acupuncture showed a clinically and statistically significant benefit with reducing symptoms of depression on objective measures.
