英文摘要：

[Objective] To research the biomechanical parameters based on lever positioning manipulation on lumbar disc herniation, and to make the quantitative and standardization of the manipulation. [Methods] Three dimensional motion analysis system and video analysis test system were used to gather the data of operation synchronously. The Kmplayer player was used to play the video, and the high-level function of the software was used to get a series of529 pictures. The picpick image editor software was used to measure the angle. The Photoshop software was used to measure displacement and calculate the angular velocity.[Results] The degree of the angle of the volunteers of hip and knee joint marker line and the horizontal line is 76.33 ±0.82. The sum of the displacement of the operator left elbow is 7.38±0.68 cm. The sum of the displacement of the volunteers left knee joint is 6.67 ±0.37 cm. The angular velocity of the trigger point from the start is 15.28 ±3.18 degree/sec, and the angular velocity of the maximum angle from the trigger point is 31.82 ±8.83 degree/sec.[Conclusion] We get the key angle, displacement and angular velocity by using the method of video image analysis. We provide the scope of the manipulation and the biomechanical parameters for the standardized operation.
