摘要:

背景:落环锁式膝踝足矫形器在较高位脊髓损伤患者中被广泛应用,但该矫形器在行走时有一个主要限制即摆动期膝关节锁定,导致患者在行走时需要通过上肢活动来补偿。目前有关不同矫形器治疗效果的对比鲜有研究。
目的:探究并对比E-MAG活跃型矫形器和落环锁式膝踝足矫形器在脊髓损伤患者步态提升中的临床效果。
方法:采用自身交叉对照研究的实验设计,观察E-MAG活跃型矫形器和落环锁式膝踝足矫形器在1例T10脊髓水平损伤患者中的应用效果。通过测量下肢的三维步态数据,对比摆动期允许膝关节屈曲、支撑期膝关节锁定和整个步态周期中膝关节均锁定两种步态的差异。
结果与结论:定性观察和运动学三维步态数据证明该患者在使用E-MAG活跃型矫形器时行走更快,更有效。尽管患者无法自主控制其膝关节,由于摆动期膝关节屈曲,支撑期膝关节锁定,使用E-MAG活跃型矫形器可以帮助患者在行走时更加安全和顺利,且需要的上肢补偿更加少。与落环锁膝式膝踝足矫形器相比,E-MAG活跃型矫形器包含站立期控制,因此会有更高的接受度和实用性

Abstract:

BACKGROUND: Drop ring lock knee-ankle-foot orthosis has been widely used in patients with higher level spinal cord injury, with one primary limitation in ambulation being attributable to the absence of knee flexion in swing phase. As a result, an individual is forced to use compensatory upper body motions to advance the legs. At present, the research on the comparison between different knee-ankle-foot orthoses is rare.
OBJECTIVE: To investigate and compare the clinical effect of E-MAG and drop ring lock knee-ankle-foot orthosis in the treatment of the patients with spinal cord injury.
METHODS: With the approach of case crossover study, the application effect of drop ring lock knee-ankle-foot orthosis in combination with an E-MAG on a patient with a T10 spinal cord injury was observed. With the measurement of three-dimensional gait data, a comparison was made between the scenarios of having the knees locked during the entire gait cycle to that of allowing the knees to flex freely during the swing phase, yet still be locked for stability during stance.
RESULTS AND CONCLUSION: Qualitative observation and kinematic three-dimensional gait data demonstrated that this patient ambulated with a faster, more efficient gait pattern when using E-MAG. Despite having no voluntary control of knees, this orthotic option afforded the ability to walk safely and smoothly with both knees flexing during swing and knee lock in stance phase, and with less upper body compensation. Compared with drop ring lock knee-ankle-foot orthosis, E-MAG active orthosis contains stance phase control, so it has higher degree of acceptance and practicality
