AIM: to observe the effects of single maneuver therapy, single semiconductor laser exposure on stellate ganglion of the double side and colligation therapy on the headache of cervical origin.
目的:观察比较仅行手法治疗、仅行双侧星状神经节半导体激光照射及综合治疗方法对颈源性头痛的疗效。
The experimental results show that the double-exposure can not only obtain directly the phase information, where it doesn' t need laser reconstruction, but also gives quantitative results.
实验结果表明两次曝光技术不但能直接获取位相信息,不需要激光再现,而且能给出定量结果。
