用于截瘫行走的相互连接的矫形器在两个髋关节之间具有某种形式的连接。已经假设摆动腿的屈曲由站立腿的伸展驱动。本研究的目的是调查在路易斯安那州州立大学往复步态矫形器（LSU-RGO）的两个电缆周围的髋关节产生的力矩。从Southport的区域脊柱损伤中心招募了6名受试者，他们是有经验的RGO用户。电缆上安装了应变传感器来测量电缆张力。使用脚踏开关将步态分为摆动和站立阶段。每例受试者至少分析20个步骤。计算步态各阶段髋关节的力矩。其中4例受试者的前电缆未产生力矩。只有2名受试者在摆动阶段使用缆线产生了有助于髋关节屈曲的力矩。这些力矩非常低，最多只能对肢体屈曲做出很小的贡献。背部线缆产生的力矩明显阻止了双侧屈曲。得出的结论是，这些经验丰富的RGO用户所使用的前缆线无助于摆动肢体的屈曲。
Reciprocally linked orthoses used for paraplegic walking have some form of linkage between the two hip joints. It has been assumed that flexion of the swinging leg is driven by extension of the stance leg. The aims of this study were to investigate the moments generated around the hip joint by the two cables in a Louisiana State University Reciprocating Gait Orthosis (LSU-RGO). Six (6) subjects were recruited from the Regional Spinal Injuries Centre at Southport, who were experienced RGO users. The cables were fitted with strain gauged transducers to measure cable tension. Foot switches were used to divide the gait into swing and stance phases. A minimum of 20 steps were analysed for each subject. Moments about the hip joint for each phase of gait were calculated. There were no moments generated by the front cable in 4 of the subjects. In only 2 subjects did the cable generate a moment that could assist hip flexion during the swing phase. These moments were very low and at best could only have made a small contribution to limb flexion. The back cable generated moments that clearly prevented bilateral flexion. It was concluded that the front cable, as used by these experienced RGO users, did not aid flexion of the swinging limb.
