无动力支架和外骨骼通常由碳纤维增强塑料(CFRP)制成,可以辅助下肢运动,并且可以永久佩戴。此外,任何时候都要佩戴的支架不得阻碍方向的改变,因为这种运动几乎与日常生活中的直线步态一样重要。踝关节运动,特别是内翻和外翻,在改变行走方向中起着关键作用。然而,在传统的短腿支架的情况下,运动范围受到限制,因为放置在腿后部的单个宽CFRP叶片不能弹性变形。在这项研究中,步态辅助系统与两个CFRP刀片的外侧和内侧的腿被开发。该系统可以有效地辅助步态,并且不会抑制方向的变化。
Unpowered braces and exoskeletons, which are often made of carbon fiber reinforced plastic (CFRP), can assist lower limb movements and can be worn permanently. Furthermore, braces to be worn at all times must not hinder the change of direction, as this movement is nearly as essential as straight gait in daily life. Ankle joint movements, especially inversion and eversion, play a key role in changing the direction during walking. However, in the case of conventional short leg braces, the range of motion is limited because the single wide CFRP blade placed at the back of the leg cannot deform elastically. In this study, a gait assist system with two CFRP blades on the lateral and medial sides of the leg was developed. The system could effectively assist the gait and did not inhibit the change in the direction.
