李氏定位旋转复位法治疗椎动脉型颈椎病伴颈椎曲度异常临床观察OA

Objective To investigate the effect of Li's positioning and rotary reduction technique on hemodynamic parameters of verte-bral artery,cervical curvature,and severity of vertigo in patients with cervical spondylosis of vertebral artery type(CSA)and cervical curvature abnormality based on the tendon-bone manipulation theory.Methods A total of 60 patients with CSA and cervical curvature abnormality were enrolled and divided into observation group with 30 patients and control group with 30 patients using a random num-ber table.The patients in the control group received cervical traction combined with routine massage,while those in the observation group received Li's positioning and rotary reduction technique in addition to the treatment in the control group.A transcranial Doppler blood flow analyzer was used to monitor peak systolic blood flow velocity(Vs)and diastolic blood flow velocity(Vd)of bilateral verte-bral arteries before and after treatment;the Borden value was measured based on the lateral film of the cervical vertebra;Evaluation Scale for Cervical Vertigo(ESCV)was used to assess the severity of vertigo.Clinical outcome was compared between the two groups.Results After treatment,both groups had significant increases in Vs and Vd of bilateral vertebral arteries,Borden value,and ESCV score(P＜0.05),and the observation group had significantly greater increases in these indicators than the control group(P＜0.05).The observation group had a better clinical outcome than the control group(P＜0.05).Conclusion Li's positioning and rotary reduc-tion technique based on the tendon-bone manipulation theory can effectively improve the hemodynamic parameters of vertebral artery,cervical curvature,and the severity of vertigo in patients with CSA and cervical curvature abnormality.
