Mechanical orthoses are used for standing and walking after neurological injury. Most orthoses such as the advanced reciprocating gait orthosis typically use solid ankle-foot orthoses.
The goal of this study was to test the effects of ankle dorsiflexion assistance in patients with spinal cord injury when ambulating with an advanced reciprocating gait orthosis compared to walking with fixed ankles.
Quasi-experimental.
Four patients with spinal cord injury were fitted with an advanced reciprocating gait orthosis equipped with solid and dorsiflexion assist-type ankle-foot orthoses and walked at their self-selected speed. Joint angles and spatial-temporal parameters were measured and analyzed.
The mean walking speed and stride length were both significantly increased along with cadence by the volunteer subjects when ambulating using the advanced reciprocating gait orthosis fitted with dorsiflexion assist ankle-foot orthoses compared to the advanced reciprocating gait orthosis with solid ankle-foot orthoses. The mean ankle joint ranges of motion were significantly increased when walking with the advanced reciprocating gait orthosis with dorsiflexion assist ankle-foot orthoses compared to when using the advanced reciprocating gait orthosis with the solid ankle-foot orthoses. Knee joint ranges of motion were reduced, and hip joint ranges of motion were increased but not significantly.
The advanced reciprocating gait orthosis fitted with the dorsiflexion assist ankle-foot orthoses had the effect of improving gait parameters when compared to the advanced reciprocating gait orthosis with solid ankle-foot orthoses. Clinical relevance The advanced reciprocating gait orthosis with dorsiflexion assist ankle-foot orthoses has the potential to improve hip and ankle joint kinematics and the temporal-spatial parameters of gait in spinal cord injury patients' walking.
神经损伤后,机械矫形器用于站立和行走。大多数矫形器,如先进的往复式步态矫形器,通常使用坚固的踝足矫形器。
本研究的目的是测试脊髓损伤患者在使用先进的往复式步态矫形器行走时,与固定脚踝行走相比,踝关节背屈辅助的效果。
准实验性研究。
四名脊髓损伤患者佩戴配备了坚固和背屈辅助型踝足矫形器的先进往复式步态矫形器,并以自己选择的速度行走。测量并分析关节角度和时空参数。
与配备坚固踝足矫形器的先进往复式步态矫形器相比,志愿者受试者在使用配备背屈辅助踝足矫形器的先进往复式步态矫形器行走时,平均步行速度、步幅长度以及步频均显著增加。与使用坚固踝足矫形器的先进往复式步态矫形器相比,使用配备背屈辅助踝足矫形器的先进往复式步态矫形器行走时,平均踝关节活动范围显著增加。膝关节活动范围减小,髋关节活动范围增加但不显著。
与配备坚固踝足矫形器的先进往复式步态矫形器相比,配备背屈辅助踝足矫形器的先进往复式步态矫形器具有改善步态参数的效果。临床意义配备背屈辅助踝足矫形器的先进往复式步态矫形器有可能改善脊髓损伤患者行走时的髋关节和踝关节运动学以及步态的时空参数。
