摘　　要：目的 观察不完全性脊髓损伤患者步态对称性特点及影响因素。方法 2018年5月至2021年11月,北京博爱医院不完全性脊髓损伤患者34例,根据左右下肢运动评分的差异分为下肢对称损伤组(对称组,n=15)和下肢非对称损伤组(非对称组,n=19)。采用三维运动采集系统和足底压力采集系统进行步态测试。计算步长以及站立相和迈步相对称值。结果 对称组的步长对称值、站立相对称值和迈步相对称值均明显低于非对称组(|t|> 2.619,P <0.01)。非对称组站立相对称值和迈步相对称值与双侧下肢肌力差值呈正相关(r> 0.468,P <0.01)。判别分析显示,下肢损伤不同对称性患者的步态参数方程不同。结论 下肢运动功能对称性影响脊髓损伤患者步态对称性,左右下肢运动总分的差值是重要的影响因素。步态参数可用于判定脊髓损伤患者的下肢损伤对称性。Objective To observe the characteristics of gait symmetry and its influencing factors in patients with incomplete spinal cord injury(ISCI).Methods From May,2018 to November,2021,34 patients with ISCI in Beijing Bo'ai Hospital were divided into symmetrical injury of lower limb(SI)group and asymmetrical injury of lower limb(ASI)group according to the lower extremities motor score(LEMS).Three dimensional motion acquisition system and plantar pressure acquisition system were used for gait test.The symmetry indexes of step length,stance time and swing time were caculated.Results The symmetry indexes of step length,stance time and swing time were significant lower in SI group than in ASI group(|t|>2.619,P<0.01).Stance time and swing time significantly correlated to the difference of bilateral LEMS in ASI group(r>0.468,P<0.01).Discriminant analysis showed that gait parameter equations were different for patients with different symmetry of lower limb injuries.Conclusion The symmetry of lower limb motor function impacts gait symmetry for patients with ISCI,especially the difference value of bilateral total LEMS.Gait parameters can be used to determine the symmetry of lower limb injury in patients with ISCI.
