摘要
目的探讨半月板损伤对膝周肌肉功能的影响。方法 2017年2月至2018年2月,单侧半月板损伤患者22例,记录下蹲、站起和屈膝70°最大等长收缩时,健、患侧股外侧肌、股直肌、股内侧肌和股二头肌的表面肌电图。结果下蹲和站起时,患侧股外侧肌和股二头肌的平均肌电值显著低于健侧(t> 3.945, Z> 3.847, P <0.001),腘绳肌共同活动比率明显高于健侧(t> 3.650, P <0.01)。在70°最大等长收缩时,患侧股外侧肌、股直肌、股内侧肌和股二头肌平均肌电值均明显小于健侧(t> 2.907, Z=4.107, P <0.01)。结论 sEMG能定量评价半月板损伤患者不同运动状态下膝屈伸肌功能。半月板损伤患者患肢膝周肌肉功能下降,协调性异常,应在康复治疗过程中加以纠正。
Objective To investigate the influence of meniscus injury on the function of muscles around knee in patients with meniscus injury.Methods From February,2017 to February,2018,the suface electromyography of vastus lateralis(VL),rectus femoris(RF),vastus medialis(VM)and biceps femoris(BF)were recorded and analyzed in 22 patiens with unilateral meniscus injury,during squatting down-standing up test and maximal isometric voluntary contraction at knee flex‐ing 70°.Results During squatting down-standing up test,the average electromyography(AEMG)of VL and BF was less in affected knee than in unaffected knee(t>3.945,Z>3.847,P<0.001),and the coactivity ratio of hamstrings in affected knee was higher(t>3.650,P<0.01).The AEMG of VL,RF,VM and BF was less in affected knee than in unaffected knee(t>2.907,Z=4.107,P<0.01)during maximal isometric voluntary contraction at knee flexing 70°.Conclusion sEMG can be used to quantitatively evaluate the muscle function around knee for patients with meniscus injury in different motion states.Patients with meniscus injury demonstrate impaired muscular function and altered muscle balance around knee,which need to be corrected during rehabilitation.
