摘要
目的应用三维步态分析系统,定量分析偏瘫患者下肢的三维运动学特征,确定客观反映脑卒中后下肢偏瘫步态运动学特征的量化指标。方法对27名正常人与39例脑卒中患者采用三维步态分析系统进行运动学参数检测与分析。结果实验组脑卒中患者偏瘫侧髋、膝运动活动范围(ROM);髋伸展和踝背伸角度;髋伸展和踝背伸角度 W/S 比率与正常人群比较差异均有统计学意义(P<0.01)。脑卒中患者偏瘫侧膝 ROM、髋伸展和踝背伸与健侧比较差异有统计学意义(P<0.01);其患侧膝屈曲与健侧比较差异也有统计学意义(P<0.05)。结论脑卒中偏瘫步态下肢的运动学特征:偏瘫侧下肢关节 ROM 受限;患/健侧下肢运动不对称;说明偏瘫下肢的三维运动学参数是描述偏瘫模式的重要指标。
Objective To quantitatively analyze the three-dimensional kinematic features of the motion of lower limb joints in stroke patients with chronic hemiplegia. Methods A three-dimensional motion analysis system was used to measure the gait of 39 patients with chronic hemiplegia due to stroke, 12 males and 15 females, aged 57.11 ±9.58 （43 -75）, who could walk at least 10 m independently without a walking aid, and 27 sex and age-matched non-disabled controls. Results The values of range of motion （ROM） of hip and knee of the stroke patients were 34 -39°and 50 -58°respectively, both significantly lower than those of the controls （40 - 45 ° and 65 - 72 ° respectively, both P 〈 0.01 ）, however, the ROM of ankle of the stroke patients was 22 - 28°, not significantly different from that of the controls （26 - 30°, P 〉 0.05）. The hip extension and ankle dorsiflexion of the stroke patients were 1 -4 ° and 8 - 10° respectively, both significantly lower than those of the controls （ 14 - 19° and 14 - 16° respectively, both P 〈 0.01 ）, however, the genuflex of the stroke patients was 59 -66°, not significantly different from that of the controls （65 -69°, P 〉0.05）. The ratio of the weak and sound sides （W/S） of hip extension and the W/S value of ankle dorxiflexion of the stroke patients were 0.33 ± 0.40 and 0.65 ± 0.22, both significantly lower than those of the controls （ 1.06 ± 0.29 and 0.99 ± 0.27, both P 〈 0.01 ）, however, the W/S value of genuflex of the stroke patients was 0.90 ± 0.23, not significantly different from that of the controls （ 1.01 ± 0.07, P 〈 0.05）. Conclusion Lack of motion of lower limb joints in the weak side and asymmetry of lower limb motion between the weak and sound sides are the characteristics of the hemiplegic gait in stroke.
