Objective. To analyse the operational stability of basic acupuncture manipulation (AM) based on three-dimensional (3D) motion tracking. Method. Two quantitative indicators (spatial and temporal dispersions) and corresponding algorithms of operation stability were established based on the coordinate-time data derived from 3D motion tracking of basic AM. The differences in stability were compared between 20 acupuncture teachers and 20 acupuncture students. Results. The teachers and students had similar temporal stability, but the teachers were more stable in their spatial control, perhaps because of the teachers’ better fingertip force and more practice with feedback. Conclusion. The spatial and temporal dispersions can be used to evaluate operational stability in basic AM. Repetitive training and finger force enhancement with more accurate feedback and rhythmic auditory stimulation are recommended for improving operation stability in basic AM.

As a minimally invasive method of physical stimulation, manual acupuncture (MA) is used globally as a sort of therapy for neuromusculoskeletal disorders. In addition to selecting appropriate acupoints, acupuncturists should also determine the stimulation parameters of needling, such as the manipulation (lifting-thrusting or twirling), needling amplitude, velocity, and stimulation time. At present, most studies focus on acupoint combination and mechanism of MA, the relationship between stimulation parameters and their therapeutic effects, as well as the influence on mechanism of action are relatively scattered, and lack of systematic summary and analysis. This paper reviewed the three types of stimulation parameters of MA, their common options and values, corresponding effects and potential mechanisms of action. The purpose of such efforts is to provide a useful reference for the dose-effect relationship of MA and the quantification and standardization of its clinical treatment of neuromusculoskeletal disorders to further promote the application of acupuncture in the world.
