整复手法对骶髂关节错位骨盆及下肢生物力学的影响OA

Objective:To observe the changes in tension and symmetry of the lumbar dorsal muscle,as well as the biomechanics of the pelvis and lower limbs in patients with sacroiliac joint dislocation after reduction with reduction techniques.Method:120 patients with sacroiliac joint disloca-tion,including 60 cases of anterior and 60 cases of posterior dislocation,were selected from the Second People's Hospital Affiliated to Fujian Univer-sity of Traditional Chinese Medicine from May 2022 to March 2023.Muscle management techniques were performed first,followed by reduction techniques.The anterior dislocation was treated with hip flexion and knee flexion reduction,while the posterior dislocation was treated with posterior extension and pulling.The treatment was performed once every other day,with a total of 7 treatments.Compare the VAS score,K value of posterior catenary muscle tension,symmetrical value of posterior catenary muscle tension,pelvic tilt,torsion,horizontal rotation,as well as changes in lower limb support phase,swing phase,and foot deviation angle before and after treatment.Result:After treatment,the VAS scores,posterior superficial chain muscle tone coefficient K values,and muscle tone symmetry difference values of patients with anterior and posterior misalignment of sacroiliac joints were reduced compared with those before treatment(P<0.05);after treatment,the tilt,torsion,and horizontal rotation angles of the pelvis of pa-tients with anterior and posterior misalignment of sacroiliac joints were reduced compared with those before treatment(P<0.05);after treatment,the gait cycle of patients with anterior and posterior misalignment of sacroiliac joints in the support phase was lengthened(P<0.05)and swing phase was shortened(P<0.05)compared with the pre-treatment phase,the foot deviation angle became larger(P<0.05)in patients with anterior misalignment of sacroiliac joints compared with the pre-treatment phase,and the foot deviation angle in patients with posterior misalignment became smaller(P<0.05)compared with the pre-treatment phase.Conclusion:Reconstructive techniques can reduce the tension of the lower back muscles in patients with sacroiliac joint dislocation,balance both sides of the lower back muscles,correct pelvic deviation,and improve lower limb gait.
