Functional exercise is crucial for breast cancer patients after surgery, and the use of virtual reality technology to assist patients with postoperative upper limb functional rehabilitation has gradually attracted the attention of researchers. However, the usability of the developed rehabilitation system is still unknown to a large extent. The purpose of this study was to develop a virtual reality upper limb rehabilitation system for patients after breast cancer surgery and to explore its usability.
We built a multidisciplinary team based on virtual reality and human-computer interaction technology and designed and developed an upper limb function rehabilitation system for breast cancer patients after surgery. Breast cancer patients were recruited from a grade III-a general hospital in Changchun city for the experiment. We used the System Usability Scale to evaluate the system availability, the Presence Questionnaire scale to measure the immersive virtual reality scene, and the Simulator Sickness Questionnaire subjective measurement scale for simulator sickness symptoms.
This upper limb rehabilitation system hardware consisted of Head-mounted Display, a control handle and notebook computers. The software consisted of rehabilitation exercises and game modules. A total of 15 patients were tested on this system, all of whom were female. The mean age was 54.73±7.78 years, and no patients were excluded from the experiment because of adverse reactions such as dizziness and vomiting. The System Usability Scale score was 90.50±5.69, the Presence Questionnaire score was 113.40±9.58, the Simulator Sickness Questionnaire-nausea score was 0.93±1.16, the Simulator Sickness Questionnaire-oculomotor score was 0.80±1.27, the Simulator Sickness Questionnaire-disorientation score was 0.80±1.27, and the Simulator Sickness Questionnaire total score was 2.53±3.40.
This study fills in the blanks regarding the upper limb rehabilitation of breast cancer patients based on virtual reality technology system usability research. As the starting point of research in the future, we will improve the system's function and design strictly randomized controlled trials, using larger samples in the promotion, to evaluate its application in breast cancer patients with upper limbs and other physiological functions and the feasibility and effects of rehabilitation.
功能性锻炼对于乳腺癌术后患者至关重要，利用虚拟现实技术辅助患者进行术后上肢功能康复逐渐引起研究者的关注。但开发的康复系统的可用性在很大程度上仍不为人知。本研究旨在开发一种用于乳腺癌术后患者的虚拟现实上肢康复系统，并探讨其可用性。
我们基于虚拟现实和人机交互技术组建了多学科团队，并设计和开发了一种用于乳腺癌术后患者上肢功能康复的系统。在长春市一家三级甲等综合医院招募乳腺癌患者进行实验。我们使用系统可用性量表评估系统可用性，使用沉浸感问卷量表测量沉浸虚拟现实场景，使用模拟器疾病主观测量量表评估模拟器疾病症状。
该上肢康复系统硬件包括头戴式显示器、控制手柄和笔记本电脑。软件包括康复练习和游戏模块。共有 15 名患者在该系统上进行了测试，均为女性。平均年龄为 54.73±7.78 岁，无因头晕、呕吐等不良反应而被排除实验的患者。系统可用性量表评分为 90.50±5.69，沉浸感问卷量表评分为 113.40±9.58，模拟器疾病问卷-恶心量表评分为 0.93±1.16，模拟器疾病问卷-眼动量表评分为 0.80±1.27，模拟器疾病问卷-定向障碍量表评分为 0.80±1.27，模拟器疾病问卷总分评分为 2.53±3.40。
本研究填补了基于虚拟现实技术的乳腺癌患者上肢康复系统可用性研究的空白。作为未来研究的起点，我们将严格进行随机对照试验，提高系统功能和设计，使用更大的样本进行推广，评估其在乳腺癌患者上肢和其他生理功能康复中的应用的可行性和效果。
