“…In chronological order, the pattern of acupuncture training changed from comparing motion patterns regarding the position of the needle, to comparing force. Force refers to the sensation of the needle in the tissue during needling [59], as well as the pressing force of the assisting hand during needle manipulation.…”

The purpose of this review was to identify research trends in acupuncture training systems and models and to analyze acupuncture training using phantom models. Articles on acupuncture training were retrieved from domestic and foreign electronic databases (PubMed, CNKI, CiNii, NDSL, KISS, RISS and KMBase). The search included studies conducted from January 1, 2010 to October 1, 2021. Acupuncture training was analyzed by categorization into acupoint location training and needling training. Acupuncture training was most frequently studied in China, acupoint location training was the most studied in 2012, and needling training was the most studied in 2013 and 2020. Among them, a silicone model with a sensor was used for training in acupoint location, and silicone and agarose gel were frequently used for needling training. Classifications of the phantom models for needling training by topic included phantom development, phantom-based education and evaluation system, phantom-based quantitative measurement, comparison of kinematic characteristics of hand motion between experts and beginners, and phantom models for acupoint location and needling training. Further research on the development of acupuncture practice training systems to improve practical skills is needed.

“…The interaction with the tissue when the acupuncture needle is inserted vertically can be classified according to stiffness, cutting, and friction forces [26]. However, Son et al [27] argues that the only force experienced from the tissue is friction force. Jiang et al [24] describes the amount of friction force generated when the needle is perpendicular to the phantom tissue as follows:…”

Background: Various factors can alter the efficacy of acupuncture treatment, such as the location of points, manipulations, depth of insertion, needle retention time, and needle type. In this study, the effect of needle diameter on the efficacy of acupuncture treatment was quantitatively evaluated. Methods: Five acupuncture needles of different diameters used in clinical practice were compared. Force on the porcine tissue phantom was measured using a sensor. Lifting-thrusting and twisting-rotating movements were performed using a needle insertion-measurement system. After repeated measurements, force magnitude was calculated and compared. Following this, we correlated needle diameter and force magnitude during lifting-thrusting and twisting-rotating movements. Results: The force magnitude was significantly altered between needle diameters during lifting-thrusting movements, as shown by a significant positive correlation between needle diameter and force magnitude. In contrast, there was no difference in force magnitude with different needle diameters during twisting-rotating movements. Conclusion: Needle diameter can significantly affect stimuli and force magnitude dependent upon the type of manipulation. Research into the effect of other needle type characteristics and stimulation method is necessary to fully elucidate the role of acupuncture needle choice in treatment efficacy.

“…The paper of Langevin et al [36] considered the “de qi” reaction has a biomechanical component “needle grasp,” and it is a measurable biomechanical phenomenon associated with manipulation of MA. Except needle grasp, the friction was also identified as an important parameter related to de qi during interaction between needle body and tissues [37].…”

“…According to the movement characteristics of basic manipulation, the different micromechanical sensors mainly detect the component along three axes during lifting-thrusting, as well as the torsion and tangential force of twirling. Son et al [37] further calculated the friction coefficient of tissue to the needle body with a modified Karnopp friction model based on the measured value during the lifting-thrusting method (Figure 2(c)). The dynamic detection system developed by Ding [62] was used for measuring the interaction force between the acupuncturist and patient on needle during each kind of manipulations.…”

“…The big data accumulation of MA based on this system can provide a quantitative reference for the analysis of the effect study such as “de qi,” and the characteristic summary of different MA manipulations. At present, the corresponding research work has also begun, for instance, the identification of the “de qi” reaction based on the friction coefficient or grip strength of the needle body [36, 37] and the characteristic comparison of MA manipulations “reinforcing” and “attenuating” with kinematic parameters such as velocity and time course [15, 42, 48].…”

The therapeutic effect of manual acupuncture (MA) is closely related to the stimulation amount. In the clinical studies, the stimulation amount is often difficult to be determined. The reason is that there are many parameters affecting the stimulation amount, including manipulation selection, treatment time, needling velocity, and force, and no complete and reasonable scheme is available for the measurement of stimulation parameters. This paper reviewed the theoretical and laboratory measurement studies on MA stimulation, summarized 4 types of available parameters according to the theory of physics, and compared the advantages and disadvantages of the existing methods of parameter measurement. Such efforts are hoped for providing reference for the establishment of the stimulation parameter system of MA and possible technical solutions for future measurement experiments.
