Abstract

BACKGROUND

Wearable powered exoskeletons could be used to provide robotic-assisted gait training (RAGT) in people with stroke (PwST) and walking disability. The study aims to compare the differences in cardiac function, fatigue, and workload during activities of daily living (ADLs), while wearing an exoskeleton.

METHODS

Five PwST were recruited in this pilot cross-sectional study. We observed three experimental conditions: walking without and with the UAN.GO exoskeleton and walking with the UAN.GO combined with the OPTIGO walker. Each condition included five trials related to ADLs such as sitting and walking.

RESULTS

No statistically significant difference was found between heart rate and R-R of ECG data while comparing all the observed conditions during each respective trial. The NASA Task Load Index did not show significant differences across all trials, except for a significant difference between Condition 2 and Condition 3 in Trial 4 ( = 0.043). However, walking and sit-to-stand tasks seem to be more challenging according to the NASA-TLX. Only one participant scored over 70 points on the System Usability Scale. The TSQ-WT scores for conditions 2 and 3 were 62 (56.5-72.5) and 70 (66.5-75) points, respectively.

CONCLUSIONS

This study suggests that UAN.GO exoskeleton could be used for RAGT in PwST with disability without compromising cardiovascular function.

摘要

背景

可穿戴动力外骨骼可用于为中风患者（PwST）和行走障碍者提供机器人辅助步态训练（RAGT）。本研究旨在比较穿戴外骨骼时日常生活活动（ADL）期间心脏功能、疲劳和工作量的差异。

方法

在这项试点横断面研究中招募了5名PwST。我们观察了三种实验条件：不使用和使用UAN.GO外骨骼行走以及使用UAN.GO与OPTIGO助行器结合行走。每种条件包括与ADL相关的五项试验，如坐立和行走。

结果

在每个相应试验中比较所有观察条件时，心电图数据的心率和R-R之间未发现统计学上的显著差异。除试验4中条件2和条件3之间存在显著差异（=0.043）外，NASA任务负荷指数在所有试验中均未显示出显著差异。然而，根据NASA-TLX，行走和从坐到站的任务似乎更具挑战性。只有一名参与者在系统可用性量表上得分超过70分。条件2和条件3的TSQ-WT分数分别为62（56.5-72.5）分和70（66.5-75）分。
