Abstract：Objective To explore the effect of muscle energy technique(MET)on dynamic posture control and lumbar neuromuscu-lar function in patients with non-specific low back pain.
Methods From March to June,2022,30 college students with non-specific low back pain from Shandong Sport Universi-ty were randomly divided into control group(n=15)and intervention group(n=15).The control group received health education,and the intervention group received MET,for four weeks.They were assessed with Visual Ana-logue Scale(VAS)of pain,Oswestry Disability Index(ODI),Y-balance test and trunk flexion-relaxation test be-fore and after intervention.
Results VAS scores decreased in both groups after intervention(|t|>2.449,P<0.05),and it was less in the intervention group than in the control group(t=-5.068,P<0.001);while ODI score decreased in the intervention group(t=4.785,P<0.001),and it was less in the intervention group than in the control group(t=-2.895,P=0.007);the performance of Y-balance test increased(t=-3.662,P=0.003)in the intervention group,as well as flexion-re-laxation ratio of multifidus(t=-2.460,P=0.029).
Conclusion MET is effective on alleviating pain and lumbar dysfunction,improving dynamic posture control and en-hancing the function of the multifidus during flexion in patients with non-specific low back pain.
