In mathematics and science, a nonlinear system is a system in which the change of the output is not proportional to the change of the input. Nonlinear problems are of interest to engineers, biologists, physicists, mathematicians, and many other scientists because most systems are inherently nonlinear in nature. Nonlinear dynamical systems, describing changes in variables over time, may appear chaotic, unpredictable, or counterintuitive, contrasting with much simpler linear systems.

This invention relates to the field of cervical and lumbar spine rehabilitation technology, and more particularly to a cervical and lumbar spine rehabilitation training system integrating posture monitoring and motion guidance. The system includes the following modules: a data acquisition and preprocessing module, used to collect real-time three-dimensional posture data of the user's cervical, thoracic, and lumbar spine and related joints, and generate motion data after standardization processing; and a micro-deviation analysis module, which generates a personalized micro-deviation accumulation model based on the motion data, predicts micro-deviations in real time, and generates personalized training adjustment strategies based on the user's physiological characteristics, historical training data, and current movements. In this invention, the micro-deviation analysis module extracts joint position, angle, velocity, and acceleration features from the standardized motion data, and combines this with nonlinear system modeling, user physiological characteristics, and historical training data to realize a personalized micro-deviation accumulation model, generating real-time micro-deviation prediction and training adjustment strategies.
