Nevertheless, we could see that brain regions such as SII, insula, cingulate gyrus, amygdala / hippocampal formation and prefrontal cortices might be important when differentiating the acupuncture specific effect from sham acupuncture.

Whereas, on greater deactivation from verum than sham acupuncture or greater activation for sham (2b, sham > verum, 21 subjects, 3 experiments and 27 foci) the result showed significant convergence in supramarginal gyrus, superior temporal gyrus and cuneus (Table 5, Figure 4B).

Qin et al. [150], [151] identified an amygdala - related network during the resting state both after verum and penetrating sham acupuncture at a nearby point.

Of six studies, two studies [47], [48] showed no differences between verum and sham acupuncture.

The ALE subtraction analysis for the comparison of verum versus sham acupuncture should be interpreted with caution because the groups are disparate in total number of foci.

(D) Differences in brain response between verum and sham acupuncture from subtraction analysis showed more activation in the sensorimotor affective / cognitive processing brain regions and more deactivation in the amygdala / hippocampal formation for verum acupuncture.

Five other studies [40]--[44] found no significant difference between verum and sham acupuncture.

The Subtraction analysis for verum versus sham acupuncture included in the first step analyses 3a — d for the pre-post contrast on verum or sham acupuncture compared to baseline (Table 5, Figure 4C).

Comparing results on greater activation of sham acupuncture points than baseline (3c, sham > rest) from 164 subjects, 15 experiments and 200 foci, showed significant convergence in cerebellum, supramarginal gyrus, superior temporal gyrus and thalamus.

In addition, Napadow et al. [51] found that both verum and sham acupuncture showed linearly decreasing activation over repeated stimulus blocks in the sensorimotor areas, while verum acupuncture produced bimodal activity in a limbic midbrain region - activation in early blocks, but deactivation in later stimulus blocks.

From the studies which had both verum and sham acupuncture groups: 3a) greater activation of verum acupuncture points than baseline (verum > rest), 3b) greater deactivation of verum acupuncture points than baseline (rest > verum), 3c) greater activation of sham acupuncture points than baseline (sham > rest), 3d) greater deactivation of sham acupuncture points than baseline (rest > sham), 3e) comparison ALE map of greater activation of verum than sham acupuncture relative to rest («verum > rest» - «sham > rest»), 3f) comparison ALE map of greater deactivation of verum than sham acupuncture relative to rest («rest > verum» - «rest > sham»).

In clinical studies large effects produced by sham acupuncture were observed [4]--[6].

From the studies which provided direct contrasts between verum and sham acupuncture: 2a) greater activation from verum than sham acupuncture (or greater deactivation for sham, i.e. verum > sham), 2b) greater deactivation from verum than sham acupuncture (or greater activation for sham, i.e. sham > verum).

The convergence of brain regions shown for these meta - analyses comparing verum and sham acupuncture overlapped for middle cingulate gyrus.

However, for the sham acupuncture group, more differences were observed in contralateral operculum, ipsilateral insula, inferior frontal gyrus, medial frontal gyrus and superior frontal gyrus.

Including data on greater deactivation of sham acupuncture points compared to baseline (3d, rest > sham) from 50 subjects, 5 experiments and 52 foci, resulted in significant convergence in pregenual anterior cingulate, subgenual cortex and parahippocampal gyrus.

Studies also have found that traditional acupuncture works differently than sham acupuncture in the brain.

«Importantly, the results of this trial show that even sham acupuncture — which is effectively a placebo — is more effective than medications.

«Real acupuncture no better than sham acupuncture for treating hot flushes: Study.»

Only one woman reported an episode of drowsiness from the sham acupuncture, whereas the placebo pill recipients reported eight adverse events such as headache, fatigue, dizziness and constipation.

They were followed by the group that had received the «sham acupuncture» treatment.

After all, wouldn't everyone want a treatment — be it sugar pill «drug» or sham acupuncture — that made them feel better without producing the side effects associated with active medications?

Some of the best support for this contention came in 2012, when researchers at Memorial Sloan Kettering Cancer Center and their colleagues published a meta - analysis of 29 studies involving nearly 18,000 patients, which found that traditional acupuncture produced a somewhat greater reduction in pain than placebo or sham acupuncture.

Not exact matches

For one thing, they point out, acupuncture studies are extremely difficult to double - blind — a methodological approach in which neither the researchers nor patients know who is receiving the treatment under investigation and who is receiving the placebo or sham.

Studies have found no meaningful difference between acupuncture and a wide range of sham treatments.

They also found some evidence supporting the use of techniques such as acupuncture and spinal manipulation for acute and chronic pain — although it should be noted that several researchers have questioned whether these treatments are superior to placebo or sham therapies.

A new study has revealed traditional Chinese acupuncture treatments are no better than fake acupuncture for treating menopause symptoms., But in a surprise finding, both the real and sham treatments showed a 40 per cent improvement in the severity and frequency of hot flushes at the end of eight weeks of treatment.

Compared to sham, verum acupuncture increased the connectivity between the amygdala, the PAG (periaqueductal gray) and the insula, and decreased the connectivity between the amygdala with the middle frontal cortex, the postcentral gyrus and the posterior cingulate cortex (PCC).

From the descriptive view on the data it seems that compared to sham, verum acupuncture tended to be associated with more activation in the basal ganglia, brain stem, cerebellum, and insula and more deactivation was seen in the so - called «default mode network» and limbic brain areas, such as the amygdala and the hippocampus.
