基于平脊疗法延伸的平衡力线手法对轻度膝内翻膝骨关节炎患者的干预效果OA

Objective:To explore the intervention effect of balance-alignment tuina manipulation derived from the spine-balancing therapy of Pingle Zhenggu on lower limb alignment and clinical symptoms in patients with mild genu varum knee osteoarthritis(KOA).Methods:A total of 80 patients with mild genu varum KOA admitted to the Center for Neck,Shoulder,Low Back and Leg Pain of Henan Luoyang Orthopedic Hospital from January 2024 to January 2025 were enrolled.The patients were divided into an observation group and a control group using the random number table method,with 40 cases in each group.The control group was treated with lower limb traction(traction weight:5～7 kg,40 min per session,twice a day with an interval of 4 h between sessions),traditional Chinese medicine fumigation and washing(30 min per session,twice a day with an interval of 4～6 h between sessions),conventional tuina manipulation(30 min per session,3 times a week),as well as functional exercises including straight leg raising,wall squatting and quadriceps contraction(3 sets a day).On the basis of the control group's regimen,the observation group replaced conventional tuina manipulation with balance-alignment tuina manipulation.Both groups received continuous treatment for 3 weeks.The visual analog scale(VAS)score,Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score,knee joint range of motion(ROM),hip-knee-ankle angle(HKA)and joint line convergence angle(JLCA)measured by weight-bearing full-length DR radiography of the lower limbs were compared between the two groups before and after treatment.Moreover,the clinical therapeutic efficacy of the two groups was evaluated and compared.Results:Before treatment,there were no statistically significant differences in VAS score,WOMAC subscores(pain,stiffness and physical function)and total score,knee joint ROM,HKA and JLCA between the two groups(P>0.05).After treatment,the VAS score,WOMAC subscores(pain,stiffness and physical function)and total score in both groups were significantly decreased(P<0.05),while the knee joint ROM and HKA were increased and the JLCA was decreased when compared with the baseline data(P<0.05).Furthermore,the improvement of the above indicators in the observation group was significantly superior to that in the control group(P<0.05).The clinical excellent and good rate of the observation group after treatment was 97.5%,which was significantly higher than 62.5%of the control group(P<0.05).Conclusion:The balance-alignment tuina manipulation derived from the spine-balancing therapy of Pingle Zhenggu can effectively correct the lower limb alignment,alleviate joint pain,and improve joint function in patients with mild genu varum KOA.Its clinical efficacy is superior to that of conventional tuina manipulation,providing a characteristic technical reference of Pingle Zhenggu for the non-surgical treatment of KOA.
