This study performed an evaluation of technology acceptance of the therapeutic system E-BRAiN (Evidence-Based Robot Assistance in Neurorehabilitation) by stroke survivors receiving therapy with the system. The evaluation was based on a 49-item questionnaire addressing technology acceptance (I) with its constituents, i.e., perceived usefulness, perceived ease of use, perceived adaptability, perceived enjoyment, attitude, trust, anxiety, social influence, perceived sociability, and social presence (41 items), and (II) more general items exploring user experience in terms of both technology acceptance (3 items) and usability (5 open-question items). Eleven consecutive sub-acute stroke survivors who had received either arm rehabilitation sessions (n = 5) or neglect therapy (n = 6) led by a humanoid robot participated. The multidimensional "strength of acceptance" summary statistic (Part I) indicates a high degree of technology acceptance (mean, 4.0; 95% CI, 3.7 to 4.3), as does the "general acceptance" summary statistic (mean, 4.1; 95% CI, 3.3 to 4.9) (art II) (scores ranging from 1, lowest degree of acceptance, to 5, highest degree of acceptance, with a score of 3 as neutral experience anchor). Positive ratings were also documented for all assessed constituents (Part I), as well as the perception that it makes sense to use the robot technology for stroke therapy and as a supplement for users' own therapy (Part II). A high degree of technology acceptance and its constituents, i.e., perceived functionality and social behaviour of the humanoid robot and own emotions while using the system, could be corroborated among stroke survivors who used the therapeutic system E-BRAiN.
本研究对接受治疗系统E-BRAiN（神经康复中的循证机器人辅助）治疗的中风幸存者对该治疗系统的技术接受度进行了评估。该评估基于一份49项的问卷，该问卷涉及技术接受度（I）及其组成部分，即感知有用性、感知易用性、感知适应性、感知愉悦性、态度、信任、焦虑、社会影响、感知社交性和社会临场感（41项），以及（II）从技术接受度（3项）和可用性（5项开放式问题）方面探索用户体验的更一般性项目。11名连续的亚急性中风幸存者参与了研究，他们接受了由人形机器人主导的上肢康复训练（n = 5）或忽视症治疗（n = 6）。多维“接受强度”汇总统计量（第一部分）表明技术接受度较高（均值为4.0；95%置信区间为3.7至4.3），“总体接受度”汇总统计量（均值为4.1；95%置信区间为3.3至4.9）（第二部分）也是如此（分数范围从1，最低接受度，到5，最高接受度，以3分为中性体验锚点）。所有评估的组成部分（第一部分）以及认为使用机器人技术进行中风治疗并作为用户自身治疗的补充是合理的这一认知（第二部分）也都有积极的评分记录。在使用治疗系统E-BRAiN的中风幸存者中，可以证实其对技术的高度接受度及其组成部分，即人形机器人的感知功能和社交行为以及使用系统时自身的情绪。
