Patients with calf muscle insufficiency are often dependent on ankle-foot orthoses (AFO). The orthosis should improve walking and posture and should prevent structural deformities. AFOs are usually manufactured with a dorsiflexion stop. In the current study, orthoses with a dorsal carbon fiber spring were compared with the classic design.
Five patients with spina bifida, one with poliomyelitis, and one with a tibial nerve block took part in the study. All participants underwent a 3-D gait analysis including data collection of kinematics (VICON) and kinetics (Kistler).
It was found that the use of a carbon fiber spring significantly increases the energy return during the third rocker for a push-off effect (p<0.05). The measurements showed further that the carbon spring was able to support the patient during the complete stance phase. The analysis of the ankle and knee kinematics reveals that the spring contributes to a more physiological gait (p<0.05).
This investigation showed that the use of a carbon spring and the alignment positively influenced the gait pattern during the stance phase.
小腿肌肉功能不全的患者常常依赖踝足矫形器（AFO）。该矫形器应能改善行走和姿势，并预防结构畸形。AFO通常制作有背屈限位装置。在本研究中，将带有背侧碳纤维弹簧的矫形器与经典设计的矫形器进行了比较。
五名脊柱裂患者、一名脊髓灰质炎患者和一名接受胫神经阻滞的患者参与了本研究。所有参与者均接受了三维步态分析，包括运动学（VICON）和动力学（Kistler）数据收集。
发现使用碳纤维弹簧在第三摆动期显著增加了能量回返，以产生蹬离效应（p<0.05）。测量还显示，碳弹簧在整个站立期能够支撑患者。对踝关节和膝关节运动学的分析表明，弹簧有助于形成更符合生理的步态（p<0.05）。
本研究表明，使用碳弹簧及其对线方式对站立期的步态模式有积极影响。
