BACKGROUND:The evaluation and management of cervical vascular pathologies before orthopedic manual therapy have great significance for reducing risks,ensuring patients'interests and promoting optimal clinical decision-making.However,the research and exploration of this field in China are still in its infancy.In 2020,the International Federation of Orthopaedic Manipulative Physical Therapists(IFOMPT)released the International Framework for Examination of the Cervical Region for potential of vascular pathologies of the neck prior to Orthopaedic Manual Therapy(OMT)Intervention:International IFOMPT Cervical Framework(2020).This framework has important references and guiding values for the clinical practice of cervical manipulation in China. OBJECTIVE:To integrate and interpret the core content of the framework,to provide a reference for the clinical practice of cervical manual therapy in China. METHODS:On the basis of a full study of the framework,the authors interpret the core content of the framework from eight aspects including clinical reasoning,patient history,planning the physical examination,physical examination,risk and benefit.Meanwhile,seven databases including PubMed,EMbase,Cochrane Library,CNKI,WanFang,VIP and China Biomedical Literature Service System databases were searched by computer to screen clinical practice guidelines and expert consensus on neck pain.Through longitudinal comparison of multiple high-quality guidelines and consensus,the authors combine with the clinical practice in China to carry out discussion and analysis. RESULTS AND CONCLUSION:This framework expounds the management strategy and implementation path of cervical vascular disease evaluation before cervical manipulation from multiple dimensions,suggesting that we should improve clinicians'attention to cervical vascular disease evaluation before manipulation,and construct evaluation criteria and implementation path with Chinese clinical characteristics.Meanwhile,we should further carry out basic scientific research with multidisciplinary techniques and promote shared decision-making and teaching model innovation to achieve the best clinical decision.

BACKGROUND:Cervical rotation-traction manipulation is effective and safe in the treatment of cervical spondylotic radiculopathy,and has been widely used in clinical work.However,its effects on the biomechanics of cervical vertebra and intervertebral disc and the area of intervertebral foramen have not been systematically clarified. OBJECTIVE:Based on the finite element analysis technique,a relevant research and analysis were carried out to provide digital evidence for the mechanism of effect of cervical rotation-traction manipulation in the treatment of cervical spondylotic radiculopathy. METHODS:The CT image data of a volunteer with no neck diseases were selected as the finite element model material at its left-handed physiological limit position.The initial construction of the finite element model was completed by Mimics 19.0 software,Geomagic Studio 2013 software,Hypermash 14.0 software,and ANSYS Workbench 2020 R2 software,respectively.Based on the literature,the grid division of cervical structure and the assignment of elastic modulus and elastic coefficient were completed.Based on the previous work of the team,the mechanical effects of cervical rotation-traction manipulation were simulated on the model.Effects of cervical rotation-traction manipulation on the mechanical parameters of each vertebral body and intervertebral disc in C3-T1 segment and on the cervical lateral foramen area were analyzed. RESULTS AND CONCLUSION:(1)During cervical rotation-traction manipulation,the stress of bone structure was significantly higher than that of soft tissue such as intervertebral disc.(2)When operating the technique,the stress at the top of each cervical vertebra was higher,the stress at the bottom was lower,and the stress at the facet joint and transverse process was lower.The stress at the top of the intervertebral disc was lower,the stress at the bottom was higher,but the highest point of the intervertebral disc stress was outside the top.(3)In addition,after loading the lifting force,the projected area of the C6/C7 intervertebral foramen increased significantly compared with that before loading.(4)It is indicated that the cervical rotation-traction manipulation has the mechanical characteristics of changing the stress structure of the cervical spine itself,and can expand the C6/7 intervertebral cervical foramen area on the opposite side of the patient's cervical rotation,so as to achieve the purpose of treating cervical spondylotic radiculopathy.

Objective:To evaluate the clinical efficacy of pulsed radio-frequency(PRF) for knee osteoarthritis(KOA) using Meta-analysis.Methods:The literature of controlled clinical studies on PRF in the treatment of KOA was retrieved, the retrieval databases included China Biomedical Literature Database, The Cochrane Library, PubMed, Web of Science, Medline, Embase, CNKI, Wanfang Database, VIP Database, CBM, EBSCO and Network database. The retrieval period was the time of inception to February 2021. The retrieved literature was screened, quality evaluated and data extracted by two researchers. Statistical analysis was performed using Review Manager 5.3 software.Results:A total of 8 studies were included, including 411 patients with KOA. The 200 patients in the trial group were underwent PRF treatment and the 211 patients in the control group were underwent conventional treatment. Meta-analysis results showed that the experimental group was superior to the control group in terms of knee VAS score, WOMAC score, Lysholm score and effective rate, and the differences were statistically significant (all P<0.05). Conclusions:PRF is more effective in treating KOA than conventional treatment. The quality of the literature research in this study that met the inclusion criteria was low, and a large number of high-quality studies are needed to evaluate the efficacy and safety of PRF treatment.

The important pathogenesis of knee osteoarthritis (KOA) lies in kidney deficiency and blood stasis. Therefore, Traditional Chinese Medicine (TCM) for tonifying the kidney and activating blood circulation is widely used in clinical practise with high response. The existing literature mainly focuses on single medicine for tonifying the kidney and activating blood circulation, as well as TCM compounds, such as classic prescriptions Yougui Pill, Duhuo Jisheng Decoction, which contain TCMs for tonifying the kidney and activating blood circulation, or self-made empirical prescriptions Bushen Huoxue Recipe and Bushen Tongluo Recipe, which are based on the idea of tonifying the kidney and activating blood circulation. The above TCMs mainly regulate oxidative stress response, inflammatory cytokine level, no level, lymphatic function and microcirculation Inhibit chondrocyte apoptosis, regulate cartilage metabolism, protect and repair cartilage, and inhibit matrix degrading enzymes to play a therapeutic role.

Objective:To explore the application effect of an intelligent teaching robot system of lifting manipulation in cervical spine manipulation teaching.Methods:60 doctors were randomly divided into an experimental group ( n = 30) and a control group ( n = 30). The control group was taught by a certified chief physician using a combination of "PowerPoint presentations, video demonstrations, and operation demonstrations" . Each part is 5 min. The experimental group was taught by the intelligent teaching robot system with a spinning technique. The teaching time is 15 min for both groups. At the end of the two teaching sessions, the two groups were trained five times under different BMIs and passed the system assessment. The qualified rates of pre-traction force, lifting and pulling force, maximum force, pre-traction time, lifting and pulling time, rotation amplitude, and pitch amplitude were compared between the two groups. Results:In normal, there was significant differences between the qualified rates of pre-traction force, lifting and pulling force, maximum force, pre-traction time, lifting and pulling time, rotation amplitude, and pitch amplitude in two groups (all P<0.05). For overweight people, there were significant differences in pre-traction force, pulling force, maximum force, and rotation amplitude (all P <0.05), while there were no significant differences in pre-traction time, pulling time, or pitching amplitude (all P >0.05). In obesity, there were significant differences in pre-traction force, lifting and pulling force, maximum force, and pitch amplitude (all P <0.05), but no significant differences in pre-traction time, lifting and pulling time, or rotation amplitude (all P >0.05). Conclusions:The proposed system can improve the pass rate of spinning manipulation, especially by effectively controlling the pre-traction force, pulling force, and maximum force.
