“…5,6 Multiple physiologic models have been proposed to explain the analgesic effects of acupuncture stimulation 9 : it modulates the transmission of nervous signaling in the nociceptive pathways, activating the mesencephalic reticular formation, inhibiting the dorsal horn of spinal cord and the parafascicular thalamic nuclei; it increases the endorphin release at both spinal and supraspinal levels. 18 Recently, several clinical trials have suggested the efficacy of acupuncture as an adjuvant method for postoperative analgesia 7,8,19 ; however, conflicting results have been reported also. [10][11][12] It is difficult to achieve a definitive conclusion from reviewing the literature; the main challenge is related to the language of publications (most papers have been published only in Chinese); furthermore, most studies reach only a low level of evidence, because of methodologic bias and lack of standardized procedures.…”

“…[4][5][6] Thus, several clinical trials evaluating the efficacy of acupuncture as adjuvant method for postoperative analgesia have been published. [7][8][9] Conflicting results have been reported, [10][11][12] probably owing to the heterogeneity in acupuncture techniques that may consistently vary according to the site, timing and type of stimulation. 4 In fact, electric, chemical, or physical stimulations have been also used in several studies to increase the effectiveness of the procedure.…”

“…En el caso de la primera enfermedad, ha sido más estudiada en los casos de estrés postraumático, donde según la revisión sistemática de ensayos clínicos realizada por Kim et al (25) en el año 2013, la evidencia es prometedora pero no contundente. En lo que respecta a desordenes de ansiedad, la evidencia es un poco más sólida en casos resistentes a terapia convencional, como lo muestra el estudio de Evans et al (26) , pero aún no suficiente cuando se consolida esta información en revisiones sistemáticas (27) .…”

“…A meta-analysis of 17,922 individuals from 29 RCTs found that patients receiving acupuncture had significantly less pain than patients receiving no acupuncture (effect sizes from 0.42 to 0.57) or sham acupuncture (effect sizes from 0.15 to 0.23) for back and neck pain, chronic headache, and osteoarthritis [10] . Acupuncture as an effective treatment for post-operative pain has been well established with multiple RCTs [1114] , including a 2008 systematic review indicating that acupuncture reduces pain intensity, opioid consumption and opioid-associated side effects [7] . Studies of post-operative pain in cancer patients also favor acupuncture [6, 15] , although a recent Cochrane review was unable to draw conclusions based on the quality of evidence from prior trials [16] .…”
