Clinical observation of chiropractic manipulation in the treatment of degenerative scoliosis / 中国骨伤

OBJECTIVE@#To observe clinical efficacy of chiropractic manipulation in the treatment of degenerative scoliosis (DS).@*METHODS@#From June 2017 to September 2019, 120 patients with degenerative scoliosis were randomly divided into treatment group (60 cases) and control group(60 cases). The patients in treatment group were treated with chiropractic manipulation once every other day for 4 weeks. The patients in control group were treated with eperisone hydrochloride tablets combined with thoracolumbar orthopedic(TSLO)brace, oral eperisone hydrochloride tablets 50 mg three times a day, wearing TSLO brace for not less than 8 hours a day. The course of treatment was 4 weeks. After the patients were selected into the group, visual analogue scale (VAS) and Oswestry Disability Index (ODI) were recorded before treatment, 1, 2, 3, 4 weeks after treatment and 1 month after treatment. The full length X-ray of the spine was taken before and 4 weeks after treatment, and the scoliosis Cobb angle, sagittal vertical axis (SVA) and lumbar lordosis (LL) were measured and compared. The adverse reactions during the treatment were recorded.@*RESULTS@#There were significant differences in VAS and ODI between two groups at each time point after treatment (P<0.001), VAS and ODI at 2 weeks after treatment (PVAS=0.025, PODI=0.032) and 3 weeks after treatment(PVAS=0.040, PODI=0.044) in treatment group were significantly different from those in control group, but there was no significant difference in VAS and ODI at other time points between treatment group and control group (P>0.05). There was significant difference in Cobb angle between treatment group(P=0.010) and control group(P=0.017) after treatment, but there was no significant difference in LL and SVA between treatment group and control group. There was no significant difference in Cobb angle, LL and SVA between two groups before and after treatment. During the treatment, there were 4 mild adverse reactions in the control group and no adverse reactions in the treatment group.@*CONCLUSION@#Chiropractic manipulation can effectively relieve pain and improve lumbar function in patients with degenerative scoliosis. The onset of action is faster than that oral eperisone hydrochloride tablets combined with TSLO brace, and it has better safety and can improve Cobb angle of patients with degenerative scoliosis.

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.

Construction of fresh cervical vertebral artery determination model: influence of variant positions on vertebral artery flow / 中国组织工程研究

BACKGROUND: As a reliable biomechanical model, human fresh isolated cervical specimens provide the basis for studying the pathogenesis of cervical vertigo from the perspective of blood flow of vertebral artery.There is a lack of an in vitro cervical model that can simulate the physiological state of the cervical vertebrae and achieve complex posture, as well as can measure the blood flow of vertebral artery. OBJECTIVE:To study the influence of variant position of human fresh isolated cervical vertebrae on the blood flow of vertebral artery in vitro through constructing the fresh specimen of cervical vertebral artery determination model. METHODS: Six human fresh isolated cervical specimens were selected for constructing the vertebral artery determination model. The pressure of human vertebra artery was simulated by pressure pump. The change of normal saline height was measured by digital motion capture system dynamically under different positions. RESULTS AND CONCLUSION: (1) Eight vertebral arteries in the six models were in good condition. (2) The vertebral artery flow under neutral position was significantly richer than that under contralateral rotation-anteflexion and ipsilateral/contralateral rotation-postexion (P <0.05). (3) The vertebral artery flow under contralateral rotation-anteflexion and rotation-postexion was significantly poorer than that under natural position, ipsilateral rotation and ipsilateral rotation-anteflexion (P < 0.05). (4) In summary, the cervical vertebral artery determination model is constructed successfully that can simulate the influence of the position on vertebral artery flow. Additionally, different positions of rotation make a different effect on vertebral artery flow.
