Abstract:
OBJECTIVE:To explore the influence of individual characteristics of patients on the kinematics parameters of sitting lumbar spine manipulation.
METHODS:From January 2016 to December 2016, 30 patients with degenerative lumbar spondylolisthesis were treatede, including 18 males and 12 females, aged from 45 to 61(52.33±2.34) years old, with a course of 2 to 72(29.13±3.23) months. Motion capture technique was used to measure the kinematics parameters of the same manipulator in sitting lumbar spine manipulation for 30 patients, including rotation time, maximum speed and maximum acceleration. The parameters of the left and right hands of the operator were different. The effects of individual characteristics on the kinematics parameters of sitting lumbar spine manipulation were analyzed.
RESULTS:The kinematic and mechanical parameters of manipulation were as follows:spin time, maximum speed, maximum acceleration, the manipulation done by right or left hand showed the similar parameters(>0.05). According to multivariate linear regression, there was a significant correlation between the age of the patient and the rotation time of the operator(<0.01); the height of patient had a significant correlation with the maximum speed and maximum acceleration of the operator(<0.01).
CONCLUSIONS:There is no difference between the manipulation of left and right hand in clinical application. Age and height are important influencing factors of sitting lumbar rotation manipulation.
