Quantitative Kinesiology Study of Atlantoaxial Joint Disorders Treated by Sinew Dredging and Reduction Manipulation
Objective:To quantify the kinematic parameters of atlantoaxial joint disorders treated by sinew dredging and reduction manipulation,initially investigate the quantitative-effective relationship between manipulation and disease treat-ment,standardize the operating principles,enrich the connotation of manipulation,and popularize the application of manip-ulation.Methods:18 patients with atlantoaxial joint disorders,including 10 males and 8 females,aged 24-27(25.50± 1.10)years old,were selected to be operated by a chief spine physician with rich clinical experience and skillful manipula-tion,and the passive and rotational angles and kinematic curves of sinew dredging and reduction manipulation were quanti-fied by the motion capture system from October 2022 to May 2023.The passive angle,rotation angle and kinematic curve of the spine manipulation were quantified by a motion capture system.Results:The passive rotation angle during reduction manipulation was 72.21°±5.06°,and there was no statistically significant difference between the passive rotation angle of the affected side and the contralateral side(P＞0.05),and the rotary trigger angle of the affected side was 7.34°±1.90°,and the contralateral side was 5.61°±1.76°,with a statistically significant difference between the two sides compared to the other side(P＜0.001).Conclusion:In the clinical operation,the passive rotation angle and the rotation trigger angle should be grasped when reaching the rotationally stable state,and the rotation trigger should be emphasized on the side of the dentate process that is skewed.
