Efficacy of acupuncture on craniomandibular myofascial pain in temporomandibular disorder patients: A systematic review

“…Table 3 shows the studies that compared acupuncture with a placebo control group. And it demonstrates that the investigations by Kletschaka et al, 2010 [ 38 ], Schmid-Schawap et al, 2006 [ 39 ], and Simma et al, 2009 [ 40 ] compared needle puncture acupuncture with placebo laser acupuncture; Sales-Neto et al, 2020 [ 29 ] and Smith et al, 2007 [ 5 ] compared needle puncture acupuncture and placebo needle puncture acupuncture; and Madani et al, 2020 [ 41 ] compared laser acupuncture in two ways with placebo laser acupuncture.…”

“…The parameters evaluated by the studies were improvement in pain on palpation of orofacial areas [ 40 , 41 ], improvement in mouth opening [ 5 , [38] , [39] , [41] ], and mandibular function [ 29 ]. The improvement size of these evaluated parameters is shown in Table 3 , Table 4 .…”

“…The risk of bias analyzed Rob II resulted in seven studies with a low risk of bias [ 4 , 5 , 29 , 30 , 40 , 41 , 39 ], one with a moderate risk of bias [ 38 ], and two with a high risk of bias [ 2 , 26 ] ( Fig. 2 ).…”

“…The increased risk of bias in Simma-Kletschka et al, 2010 [ 38 ] was due to domain one not informing if the randomization sequence was random and if the allocation was hidden until the participants were selected and assigned to the respective interventions, and attributed to domain five because the article did not demonstrate whether the data were analyzed according to some predetermined plan before the results were available.…”

“…Studies [ 5 , 29 , [40] , [41] , [38] , [39] ] show the effect of acupuncture in treating myofascial pain through comparison with the control group demonstrated in Table 3 , Table 4 The efficacy of acupuncture was evidenced in all studies [ 5 , 29 , [40] , [41] , [38] , [39] ] that analyzed, needle puncture acupuncture compared to placebo laser acupuncture [ 40 , 38 , 39 ], needle puncture acupuncture compared to placebo needle puncture acupuncture [ 5 , 29 ] and laser acupuncture in two ways compared to placebo laser acupuncture [ 41 ], demonstrated by improvement in the experimental group with greater effect size in the evaluated parameters, subjective pain relief [ 5 , 29 , 40 , 38 , 39 ], pain on palpation of orofacial structures [ 40 , 41 ], gain in mouth opening [ 5 , [38] , [39] , [41] ] and mandibular function [ 29 ] when compared to the placebo group, so these results show the physiological effect of acupuncture and differ from studies [ [42] , [43] , [44] ] which infer the non-influence or limited influence of acupuncture when compared to placebo. Although there is a need to understand the mechanism of action to understand these results, the articles above do not describe it clearly, because the results found are descriptive and attribute the improvement in symptoms to the feeling of comfort and security for receiving treatment, in addition to the fact that palpation can function as an aid to muscle relaxation [ 40 , 41 ].…”
