颈椎旋转手法的数学模型及可视化研究

It were obtained that image collection, data making, three-dimensional display and three-dimensional quantitative measurment that could be rotated in any needed direction after the scanning datum of cervical bertebrae were transmitted into the computer. The display of simulation system was based on application of surface display technology. Speed of manipulation and quality of image were improved by ways of the software that can transmit primitive scanning results to target computer directly. According to results of measurment of cervical vertebral mlutiple non-linear mathematical models were established .The capacity of single and multiple motor segments' mathematical model to predict the changes on the test points were tested by use of regression and some other ways. Logarithm model being apparently not adequate for the purpose and exponential model best describing the trends of the changes of the experimental data were discoveried after correlation of cervical traction force with the pressure in the cervical nucleus pulposus and that of the traction rotation force with the puessure in the nucleus pulposus in multiple segments of the cervical vertebra being analyzeds. Changes of P in each segment of the cervical vertebra are similar in response to the load force, and there is no correlation of monotonic increase of decrease between the changes of P and the location of the cervical vertebra.

由于对颈部旋转手法没有可视化观察和研究手段，很难过其进行客观评价。本研究采用数学模型、三维重建、可视化和生物力学等技术，首次将MTS系统与三理重建技术结合。定量、惫酆透鞲鼋嵌认允咀倒苣诓拷峁沟牧⑻遄刺跎倭酥鞴坌裕岣吡司辈客颇玫淖既沸院桶踩浴６越窈罂勾死嘌芯亢陀τ闷鸬酱俳饔茫怪颇檬址ㄑ芯勘僖惶跣峦揪丁
