摘要:
目的：应用三维步态分析联合表面肌电检查研究痉挛型偏瘫脑瘫（SHCP）患儿步态动力学特征。方法：选取SHCP患儿12例为偏瘫组，招募健康儿童14例为正常组，通过三维步态分析联合表面肌电进行数据采集。比较两组下肢关节角度、力矩、功率数据，以及股直肌、股二头肌、胫骨前肌、腓肠肌内侧的均方根（RMS）值之间的差异。结果：①关节角度：两组髋关节屈曲角度在双支撑相1、单支撑相、摆动相比较差异有统计学意义（均P＜0.001）；膝关节伸展角度在双支撑相比较差异有统计学意义（P＜0.001）；踝关节背屈角度在四个时相比较差异有统计学意义（均P＜0.001）。②关节力矩：两组髋关节、膝关节伸展力矩、踝关节跖屈力矩在单支撑相比较差异有统计学意义（均P＜0.001）；踝关节跖屈力矩在双支撑相比较差异有统计学意义(P＜0.001)。③关节功率：两组髋关节、膝关节、踝关节在双支撑相1能量吸收比较差异有统计学意义(均P＜0.001)；膝关节在单支撑相、踝关节在双支撑相2能量释放比较差异有统计学意义(均P＜0.001)。④表面肌电RMS：两组股二头肌及腓肠肌在双支撑相比较差异有统计学意义（均P＜0.05）；股直肌、胫骨前肌及腓肠肌在摆动相比较差异有统计学意义（均P＜0.05）；腓肠肌在单支撑相比较差异有统计学意义（P＜0.05）。结论：三维步态分析联合表面肌电能够客观量化SHCP患儿步态特征差异性。与正常儿童相比，SHCP患儿下肢关键肌群离心收缩力下降，值得在步态治疗中进一步探索。
Abstract:
Objective:To analyze the gait dynamics of children with spastic hemiplegic cerebral palsy (SHCP) by three-dimensional gait analysis combined with surface electromyography.Methods：Twelve SHCP children were enrolled as the hemiplegia group,and 14 healthy children were enrolled as the normal group.Three-dimensional gait analysis combined with surface electromyography was used for data acquisition.Comparisons were made between the two groups regarding joint angle,moments,power,and root mean square (RMS) values of the rectus femoris,biceps femoris,tibialis anterior,and medial gastrocnemius muscles in the lower limbs.Results:①Joint angles：there were significant differences in hip flexion angles between the two groups in double support phase 1,single support phase,and swing phase (all P<0.001),knee extension angles in double support phase (P<0.001),and ankle dorsiflexion angles in the four phases (all P<0.001).②Joint moment：There were significant differences in the extension moment of the hip and knee joints and the plantar flexion moment of the ankle joints between the two groups in the single support phase (all P<0.001),and there was a significant difference in ankle plantar flexion moment between the two support phases (P<0.001).③Joint power：there were significant differences in the energy absorption of hip,knee,and ankle joints between the two groups in the dual support phase 1 (all P<0.001),and the energy release of knee joint in single support phase and ankle joint in double support phase 2 were statistically different (all P<0.001).④RMS of surface electromyography：there were significant differences in biceps femoris and gastrocnemius between the two groups in the double support phase (all P<0.05);there were significant differences in rectus femoris,tibialis anterior and gastrocnemius in the swing phase (all P<0.05);there were significant differences in gastrocnemius in the single support phase (P<0.05).Conclusion:Three-dimensional gait analysis combined with surface electromyography can provide an objective quantification of the differences in gait characteristics of children with SHCP.Compared with the healthy participants,children with SHCP exhibit decreased eccentric contraction strength in key lower limb muscle groups.This warrants further exploration in gait therapy for children with SHCP.
