“…It is speculated that differences between verum and sham acupuncture may also occur in the temporal domain, which may be resolved by neuroimaging modalities such as MEG. One preliminary data indicate that electroacupuncture and sham acupuncture (noninsertive tapping) can both evoke responses in the primary somatosensory cortex (SI) [60,61]. However, initial response to sham acupuncture peaks at longer post-stimulus latencies (~35 milliseconds) than verum EA (~20 milliseconds).…”

Acupuncture, an ancient therapeutic technique, is currently gaining popularity as an important modality of alternative and complementary medicine in the West world. Concurrently, scientific interests in exploring whether acupuncture is therapeutically effective are raised alongside those about the means by which it may operate. Modern neuroimaging techniques such as functional magnetic resonance imaging, positron emission tomography, electroencephalography, and magnetoencephalography provide a means to safely monitor brain activity in humans. In this review, we have summarized evidence derived from the neuroimaging studies and tried to elucidate the neurophysiological correlates of acupuncture. Previous investigations on the neural responses to acupuncture mainly focus on its acute effects and explore the correlation between the specific acupoints and cortical activations only in the spatial domain. However, abundant clinical reports and psychophysical analysis suggest the kinetics of acupuncture is longer acting as a function of time. Consequentially, an accurate interpretation of acupuncture actions depends on how effectively we can characterize the nature of temporal variations underlying neural activities, rather than simply detect the occurrence of such changes. This emerging picture indicates that both designing paradigms and statistical models involved in acupuncture studies should be applied with great care.

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.

Submit Manuscript | http://medcraveonline.com but Helmholtz's hypothesis [5,6] is one of the most accepted theories that try to explain it. According to the Helmholtz´s model, the contraction of the ciliary muscle would allow relaxation of crystalline capsule, which, by elastic contraction, would deform the lens, increasing its thickness and, therefore, the optical power. When the ciliary muscle relaxes, the zonular tension will increase, tensioning the lens. This tension reduces its anteroposterior dimension and increases the focal distance.The aim of acupuncture is to treat health problems by application of stimuli through the skin, with insertion of needles at specific points [7,8]. The mechanisms of action of acupuncture are unknown, but evidences point to possible neurochemical phenomena [9][10][11]. Ancient reports in the literature of Traditional Chinese Medicine (TCM) show that the stimulation of certain acupuncture points can improve visual acuity, particularly in cases of myopia and presbyopia [12]. To determine the effects of near visual acuity, we chose the Sizhukong acupuncture point (TH23), among other related points such ST4, B2, GB 37, ST 30 and L3 [13]. This article reports a clinical case of a presbyopic subject undergoing stimulation of the Sizhukong acupuncture point (TH23) and analyzes the behavior of her vision at near after needling. Case ReportG. A. L., Female, 56 years old, Brazilian, native of Guaratinga -Ba, from São Paulo, housewife, elementary school incomplete, catholic. This patient complaint of progressive loss of vision at near for about fifteen years ago. She refers low vision at near with her current reading glasses (+1.50 SPH). There is not pathological personal history, regular use of medication, or surgical history. The patient was orthophoric and remained orthophoric under cover/uncover test. Biomicroscopy and fundoscopy were normal. It could be observed phacosclerosis, but no cataracts. Tonometry In the Table 1 below the parameters of the patient's ophthalmic examination at first day are presented: Patient was under gone to bilateral needling of Sizhukong acupuncture point (TH23) with 25 X 40mmstainless steel needle at 7:20 a.m. The acupuncture's technic consisted of to prick the selected point before to leave needle resting for 20 minutes. After acupuncture session, the patient remained 20/20 in both eyes and gradually showed gain of visual acuity at near until to reach J1 line on Jaeger's table, without addition.No miosis was observed associated with gain of the amplitude of accommodation. After acupuncture session, visual acuity, amplitude of accommodation, vision at near and addition were evaluated at 7:50 a.m., 9:00 a.m., 14 p.m., 16 p.m., and 20 p.m. The findings of second day of examination are displayed in the next Table 2: It is notorious the gain of the accommodation amplitude of 3.50 D after the needling of Sizhukong acupuncture point (TH23).
