Abstract
Mastication myalgia is the most common cause of non-odontogenic pain in the orofacial region and is often associated with a reduced quality of life. The purpose of this review is to provide an overview of the clinical aspects of myalgia based on available research. The review includes epidemiological, diagnostic, and etiological aspects. In addition, the potential risk factors related to the transition from acute to chronic myalgia are explored and treatment strategies are presented for its management. As a result, this review may increase clinical knowledge about mastication myalgia and clarify strategies regarding prevention, diagnostics, and management to improve prognosis and reduce patient suffering.

Al‐Moraissi EA, Goddard G, Christidis N. Are acupuncture and dry needling effective in the management of masticatory muscle pain: A network meta‐analysis of randomised clinical trials. J Oral Rehabil 2022; 50:87-97. [PMID: 36314254 DOI: 10.1111/joor.13382] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 09/05/2022] [Accepted: 10/18/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Several studies have shown that both acupuncture and dry needling are effective in the treatment of musculoskeletal pains. Therefore, the aim of this network meta-analysis (NMA) was to investigate the treatment outcome of acupuncture and dry-needling for masticatory muscle pain (TMD-M) and to compare with active and inactive placebo. MATERIAL AND METHOD An electronic search was performed to identify randomised controlled trials (RCTs) published until September 2019, comparing dry-needling, acupuncture, and inactive as well as active placebo in patients with TMD-M. Outcome variables were post-treatment pain intensity, pressure pain threshold (PPT), and maximum mouth opening (MMO). The quality of evidence was rated according to Cochrane's tool for assessing the risk of bias. Mean difference was used to analyse via frequentist NMA using STATA-software. RESULTS Both NMA and direct pairwise meta-analysis have shown that there was no difference between active treatment with either acupuncture or dry-needling when compared to active and inactive placebo in patients with TMD-M with respect to pain intensity, and PPT (p > .05). However, there was a significant increase in MMO following dry-needling when compared to the placebo (very low-quality evidence). CONCLUSION Despite the short-term positive effect of MMO by dry-needling, this NMA could not show any pain-reducing effect in patients with TMD-M by acupuncture or dry-needling when compared to an active or inactive placebo. Taken together, this NMA indicates that it is the placebo effect that accounts for the majority of the treatment effect of TMD-M, rather than a real therapeutic effect of acupuncture/dry-needling.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is a disabling side effect caused by neurotoxic chemotherapy. This randomized controlled trial aimed to evaluate the effect of manual acupuncture on CIPN. Twenty eligible breast cancer patients receiving taxane chemotherapy treatment were recruited and randomly divided into verum acupuncture and sham acupuncture groups. Each group received 15 treatments over 9 weeks. Quantitative tactile detection thresholds were measured using Semmes–Weinstein monofilament testing (SWM). The World Health Organization Quality of Life scale (WHOQOL-BREF), the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx), and the Brief Pain Inventory-Short Form (BPI-SF) were measured before and after treatment. The between-group comparison of SWM revealed that the verum acupuncture group had more improvement of touch perception thresholds compared to the sham acupuncture group. The average pain severity in the BPI-SF of the verum acupuncture group was significantly lower than that of the sham acupuncture group. There were no significant differences in the FACT/GOG-Ntx trial outcome index and WHOQOL-BREF scores between the acupuncture and sham groups. The results suggest that acupuncture can alleviate the neuropathic pain of CIPN and improve touch perception thresholds.

Anesth Pain Med 2021; 11:e113627. [PMID: 34336626 PMCID: PMC8314077 DOI: 10.5812/aapm.113627] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 03/22/2021] [Accepted: 03/26/2021] [Indexed: 12/16/2022] Open
Abstract
CONTEXT Neck pain is a common phenomenon and affects a large segment of the population. Chronic neck pain, lasting more than 3 months, likely occurs in 10% - 30% of patients with acute neck pain and affects up to 288 million cases globally, carrying a significant cost in terms of quality of life, disability, and healthcare dollars. Here we review neck pain background, acupuncture and the evidence that exist to support acupuncture use in chronic neck pain. RESULTS Neck pain not only affects quality of life directly, but also contributes to depression, job dissatisfaction and reduced productivity. Unfortunately, neck pain is strongly linked to office and computer work and is likely to continue increasing in prevalence. Traditional treatments, such as analgesics, physical therapy, exercise, and non-invasive therapy bring some relief, and invasive therapy is indicated if anatomical pathologies exist. Acupuncture is a form of integrative medicine, originally described and practiced in traditional Chinese medicine and now expanded to include methods including acupressure, dry needling, and others. Traditionally, it focused on restoring the patient's flow of Qi by puncturing specific points along the meridians. It has previously been shown to be effective in other forms of chronic pain and disability. Clinical trials studying acupuncture for neck pain have shown significant reduction in both pain and associated symptoms. These therapies are reviewed in this text. CONCLUSIONS Neck pain is a common and significant global problem. Acupuncture, dry needling, and cupping were all shown to be effective in alleviating pain both immediately after treatment, as well as provide long-lasting relief. These treatments are generally safe and inexpensive and should be considered as part of a multimodal approach for the treatment of neck pain. More head-to-head studies will provide better data to support a choice of a specific treatment over another.

Investigation of the Phenomenon of Propagated Sensation along the Channels in the Upper Limb Following Administration of Acupuncture and Mock Laser. J Acupunct Meridian Stud 2017; 10:307-316. [PMID: 29078965 DOI: 10.1016/j.jams.2017.06.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Revised: 06/22/2017] [Accepted: 06/26/2017] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND Similar to De Qi psychophysical responses, propagated sensation along the channels (PSC) is considered an important phenomenon in traditional Chinese acupuncture. In acupuncture clinical trials, different acupuncture manipulation techniques are used to enhance the propagation of sensation along the channels to facilitate an optimum therapeutic result. AIM To examine and compare the PSC reported by participants in a clinical trial following the administration of acupuncture and inactive mock laser. METHODS The study was embedded in a two-arm parallel design multicenter, randomized clinical trial, the Tennis Elbow Acupuncture-International Study-China, Hong Kong, Australia, Italy (TEA IS CHAI). Needle sensations were measured using a validated instrument, the Massachusetts General Hospital Acupuncture Sensation Spreading Scale. Ninety-six participants with lateral elbow pain were randomly allocated into two groups in a 1:1 ratio; the acupuncture treatment group (n = 47) and the mock laser control group (n = 49). Participants in both groups received the intervention at two acupoints, LI10 and LI11, consisting of 2 minutes of either standardized needle manipulation or mock laser at each acupoint with a rest period between each intervention period. Data were collected immediately following the interventions at the first and the ninth session within the clinical trial. RESULTS Although participants in both groups perceived PSC radiating to similar sites along the upper limb, the frequency of the reported radiation sites among the two intervention groups for both radiation up the limb (p < 0.05) and radiation down the limb (p < 0.001) were statistically significantly different. Among the radiating sensation sites recorded within the two study groups, the sensations were reported as radiating a greater distance down the forearm to the wrist compared to up the arm. Evaluation of PSC across the four study sites revealed a statistically significant difference in frequency of the reported radiation down the limb sites in each study group and radiation up the limb sites only in control group only (p < 0.001). CONCLUSION The findings of the study demonstrated that the PSC phenomenon is not just associated with needling but can be perceived when using a mock laser.

Psychophysical responses in patients receiving a mock laser within context of an acupuncture clinical trial: an interoceptive perspective. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 17:348. [PMID: 28673350 PMCID: PMC5496139 DOI: 10.1186/s12906-017-1859-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/14/2017] [Accepted: 06/26/2017] [Indexed: 11/10/2022]
Abstract
Background The psychophysical responses induced by verum acupuncture are characterized by a constellation of unique subjective sensory responses commonly termed De Qi. Furthermore, a variety of sham interventions have been used as a control for acupuncture clinical trials. Indeed, one such control has been mock laser which has been used as control intervention in several acupuncture clinical controlled trials. The current study aim was to examine the De Qi sensory responses and its related characteristics elicited from acupuncture and compare them to those reported following sham laser in participants enrolled in a clinical trial. Methods The study was embedded in a multi-center, two-arm randomised clinical trial, which evaluated the effect of acupuncture on lateral elbow pain. De Qi was assessed using the Massachusetts General Hospital Acupuncture Sensation Scale (MASS). Ninety-six participants were randomly allocated to receive either acupuncture (n = 47) or mock laser (n = 49) at the acupoints LI 10 and LI 11. Results Participants in both intervention groups reported similar De Qi psychophysical characteristics; however, both intensity and frequency of the individually perceived De Qi characteristics were significantly higher in the acupuncture group. ‘Soreness’, ‘deep pressure’, and ‘fullness-distension’ in the acupuncture group and ‘tingling’, and ‘sharp pain’ in mock laser group, were identified as the leading characteristics. Similar level of MASS De Qi Index (MDI) scores were reported for ‘Hong Kong-China’ and ‘Australia-Italy’ with a significantly higher level of De Qi reported by ‘Hong Kong-China’. Furthermore, two distinct De Qi categories were identified, namely De Qi (in line with classical sensory responses of Suan, Ma, Zhang, and Zhong) and pain. Conclusions Subjective ‘somatic or interoceptive awareness’ should be taken into account when De Qi psychophysical responses are examined. The study accentuates the necessity and the significance of further research into interoception phenomenon which may contribute to a better understanding of the placebo effect and De Qi psychophysical responses.
