Characteristics Of Loading Modes And Frequencies Of Lumbar Spine Oscillatory Manipulation And Clinical Utility Studies

Objective:In this study,the kinematics characteristics of lumbar oscillation manipulation and traditional lumbar obseque-pulling manipulation and the improvement of lumbar function before and after treatment were collected and tested in vivo to explore the optimal characteristics of mechanical loading mode of lumbar oscillation manipulation.Methods:This study selected 44 cases of patients with lumbar osteoarthritis who visited the massage department of Yueyang Hospital Integrated Traditional Chinese and Western Medicine,Shanghai University of Traditional Chinese Medicine from January 2018 to December 2018 and met the diagnostic criteria in the guidelines for clinical diagnosis and treatment of Chinese medical association and the division of orthopedics as subjects.The subjects were randomly assigned to Group one and Group two to perform the manipulation of massage.In Group one,the operation of traditional oblique-pulling manipulation was carried out first(Hereinafter referred to as technique A).After A week of elution period,the operation of oscillation adjustment manipulation was carried out(Hereinafter referred to as technique B).In Group two,the oscillation adjustment manipulation was performed first,and the traditional oblique-pulling manipulation was performed after a week of elution period.The kinematics characteristics of the two lumbar adjustment manipulations were compared,including the operator's movement characteristics,application of force and the elastic sound effect caused by joint adjustment,as well as the improvement of waist function of the subjects before and after the operation,including the hardness balance of bilateral erector spinae,lumbar activity and pain score.Results:1.There was no significant difference in gender composition before treatment between the two different cross test groups(?~2=3.30,P=0.69);There was no significant difference in age(t=0.12,P=0.90).There was no statistically significant difference in BMI(t=1.59,P=0.12).2.The comparison of the maximum loading capacity between the lumbar oscillation adjustment manipulation and the traditional lumbar obtuse manipulation showed A statistically significant difference(F=11.148,P=0.002).The loading forces of the A and B manipulations were 46.16±12.36kg and 37.28±12.91kg,A.3.When adjusting the manipulation of lumbar spine oscillation,the most likely"click"sound appears in the waist of the subject.The frequency range of the manipulation oscillation is 1.5-1.6Hz.4.After the operation of lumbar oscillation manipulation and the traditional oblique-pulling manipulation,the completion rates of joint adjustment of the two manipulations were 84.09%and 79.55%,respectively.There was no statistically significant difference between the two manipulations(?~2=0.306,P=0.58).The accuracy of joint adjustment of the two manipulations was 36.36%and 65.91%,respectively.The difference between the two manipulations was statistically significant(?~2=7.686,P=0.006),and that of B was higher than that of A was higher than B.5.Before and after the lumbar spine oscillation adjustment technique and the traditional lumbar obtuse manipulation,the differences in the hardness of the subjects'lumbar erector spine were decreased(A technique:d=-0.06±0.07;B manipulation:d=-0.07±0.06).Compare the waist muscle hardness difference change vertical ridge,A and B between two methods(F=0.299,P=0.587),there was no statistically significant difference,???stage(F=1.033,P=0.315),there was no statistically significant difference;The flexion and extension activities of the subjects'lumbar spine were improved before and after treatment(A manipulation:d=5.23±8.71;B manipulation:d=6.48±9.38).Activity change compared before and after lumbar flexion and extension,A,B between two methods(F=0.466,P=0.499),there was no statistically significant difference,???stage(F=0.125,P=0.726),there was no statistically significant difference;The activity of the left and right flexion of the lumbar spine was improved(A manipulation:d=2.87±4.59;B manipulation:d=4.85±3.02).Comparing lumbar change,left lateral flexion mobility between A and B two methods(F=5.108,P=0.029),the difference was statistically significant,?,?stage(F=1.565,P=0.218),there was no statistically significant difference;Mc Gill pain score in the lower back was decreased(A manipulation:d=-12.37±9.98;B manipulation:d=-10.86±6.02).Compare the waist Mc Gill pain score changes,A,B between two methods(F=0.697,P=0.409),there was no statistically significant difference,???stage(F=2.000,P=0.165),between the difference is not significant.
