Operation Stability Analysis of Basic Acupuncture Manipulation Based on Three-Dimensional Motion Tracking Data

Illustration of the calculation idea of the temporal and spatial dispersions based on the twisting-left action of twisting skill. (a) The time dispersion is the standard deviation of the operation time course of each type of action. The calculation of the operation time course is based on the recognition of the inflection point of the curve. (b) The 3D distribution of the end points (red points) reached by each twisting-left action; the sequence number of the red dots is the cycle sequence of the twisting-left action. (c) The smallest sphere includes all the end points and its radius can be regarded as the spatial dispersion.
