?Objective To observe the effects of acupuncture nerve entering points on musculi quadriceps femoris in lower limb spasticity after stroke with ultrasound elastography.Method 44 patients with who suffers spastic hemiplegia were divided into two groups. There were 22 patients in observation group which were treated by acupuncture nerve entering points on musculi quadriceps femoris, and 22 patients in control group which were treated only by the traditional acupuncture. Modified Ashworth Scale(MAS), clinic spasticity index （CSI）, Berg balance scale(BBS) and analysis of the tissue elastic graph and young''s modulus value were used as outcome measure pre- treatment and post- treatment after 4 weeks by two appointed raters. Result After treatment for 4 week . BBS scores in both groups were significantly increased , and the lower extremity modified ashworth scores and CSI in both groups were decreased significantly as compared with those before treatment (p﹤0.01).more observation in observation group (p﹤0.05). Longitudinal Young’s modulus values of the vastus lateralis, vastus medialis, rectus femoris and biceps femoris of therapy group were lower with before treatment during knee maximum isometric voluntary contraction (P<0.05), and observation group are more apparently than control group(P<0.01). Conclusion The method of acupuncture nerve entering points on musculi quadriceps femoris can effectively improve stroke patients lower limb function and promote the recovery of patients. The recuperative effect of opposing needling is superior to either only traditional acupuncture treatment.
