背景：脊髓损伤（SCI）导致的下肢活动能力丧失与多种生理和心理影响相关。动力外骨骼提供了恢复活动性和逆转或预防与immobility.Objective相关的继发性影响的可能性：本研究旨在评估SCI患者在使用动力外骨骼进行5次步态训练后的活动性结果，其主要目标是表征系统的易用性和可用性。在格鲁吉亚亚特兰大市的Shepherd中心，16名SCI受试者参加了一项初步临床试验，损伤程度从C5完全到L1不完全。研究Indego外骨骼研究套件的易用性和有效性进行了评估，在提供腿部的流动性。研究的结果测量包括10米步行试验（10 MWT）和6分钟步行试验（6 MWT）以及独立性测量，包括穿脱时间和在各种表面上行走的能力。在5次会议结束时（每次1.5小时），C5-6运动完全性四肢瘫痪者的平均步行速度为0.22 m/s，T1-8运动完全性截瘫者为0.26 m/s，T9-L1截瘫为0.45 m/s。C5-6的6分钟平均距离为64米，T1-8为74米，T9-L1为121米。此外，所有的参与者都能够走在室内和室外surfaces.CONCLUSIONS：结果后，只有5个会议表明，四肢瘫痪和截瘫的人学会使用Indego外骨骼迅速，可以管理各种表面。行走速度和距离的实现也表明，一些人与截瘫可以很快成为有限的社区步行使用该系统。
BACKGROUND: Loss of legged mobility due to spinal cord injury (SCI) is associated with multiple physiological and psychological impacts. Powered exoskeletons offer the possibility of regained mobility and reversal or prevention of the secondary effects associated with immobility.OBJECTIVE: This study was conducted to evaluate mobility outcomes for individuals with SCI after 5 gait-training sessions with a powered exoskeleton, with a primary goal of characterizing the ease of learning and usability of the system.METHODS: Sixteen subjects with SCI were enrolled in a pilot clinical trial at Shepherd Center, Atlanta, Georgia, with injury levels ranging from C5 complete to L1 incomplete. An investigational Indego exoskeleton research kit was evaluated for ease of use and efficacy in providing legged mobility. Outcome measures of the study included the 10-meter walk test (10 MWT) and the 6-minute walk test (6 MWT) as well as measures of independence including donning and doffing times and the ability to walk on various surfaces.RESULTS: At the end of 5 sessions (1.5 hours per session), average walking speed was 0.22 m/s for persons with C5-6 motor complete tetraplegia, 0.26 m/s for T1-8 motor complete paraplegia, and 0.45 m/s for T9-L1 paraplegia. Distances covered in 6 minutes averaged 64 meters for those with C5-6, 74 meters for T1-8, and 121 meters for T9-L1. Additionally, all participants were able to walk on both indoor and outdoor surfaces.CONCLUSIONS: Results after only 5 sessions suggest that persons with tetraplegia and paraplegia learn to use the Indego exoskeleton quickly and can manage a variety of surfaces. Walking speeds and distances achieved also indicate that some individuals with paraplegia can quickly become limited community ambulators using this system.
