背景:膝关节炎是一种破坏性疾病,影响膝关节并引起疼痛和活动能力下降。药物治疗,减肥,运动控制疾病的症状,但是这些方法只会延迟疾病的进程,最终,膝关节置换手术将是必要的。手术后,在适当的物理治疗计划的帮助下,完全恢复平均需要6-12个月。然而,目前,在伊朗没有类似的工具来促进这一进程。
目的:这项研究的目的是为膝关节置换手术后的患者设计和开发康复系统的原型,为患者提供信息和适当的物理治疗计划。
方法:本研究是开发应用的,分三个阶段进行。在第一阶段,以清单的形式准备了教育和治疗练习的需求和内容,然后在评估会议上检查了每个项目的必要性。在第二阶段,该系统的原型是使用AdobeXD软件并根据上一阶段批准的要求开发的。第三阶段,从专家的角度分析了该程序的可用性,使用了Nielsen的13条可用性原则的探索性评估方法。
结果:首先,系统需求被提取并准备在两个内容清单(51个练习)和能力清单(60个项目)中。然后在对基于德尔菲技术的专家进行调查之后,获得了内容信息(43个练习)以及功能和非功能要求(53个项目)。专家调查有助于最终确定信息要素,对它们进行分类,并准备清单的最终版本。基于此,系统需求分为11类,培训内容分为3个培训期。最后,完成了系统的设计和开发。这个系统有管理员,内科医生,和患者用户界面。可用性结果表明,该系统是有效的,并且在帮助用户检测和从错误中恢复的功能方面仅存在一些问题。
结论:似乎有必要开发一种基于治疗师和康复专家可用性原则的系统,以在家训练和监测膝关节置换术后患者的远程康复过程。而且,让利益相关者参与远程康复系统的设计和开发的重要性并不是任何人都隐藏的。卡拉系统具有上述所有功能。
BACKGROUND: Knee arthritis is a destructive disorder that affects the knee joints and causes pain and reduced mobility. Drug treatments, weight loss, and exercise control the symptoms of the disease, but these methods only delay the disease process and eventually, knee joint replacement surgery will be needed. After surgery, with the help of a proper physiotherapy program, full recovery takes an average of 6-12 months. However, currently, there is no similar tool to facilitate this process in Iran.
OBJECTIVE: The purpose of this research is to design and develop the prototype of a rehabilitation system for patients after knee replacement surgery, which provides patients with information and appropriate physiotherapy programs.
METHODS: This study was development-applied and was done in three stages. In the first stage, the needs and content of education and therapeutic exercises were prepared in the form of a checklist, and then the necessity of each item was checked in the evaluation sessions. In the second stage, the prototype of the system was developed using Adobe XD software and based on the requirements approved from the previous stage. In the third stage, the usability of the program was analyzed from the point of view of experts using the exploratory evaluation method with Nielsen\'s 13 principles of usability.
RESULTS: At first, the system requirements were extracted and prepared in two checklists of content (51 exercises) and capabilities (60 items). Then after a survey of experts based on the Delphi technique, content information (43 exercises) and functional and non-functional requirements (53 items) were obtained. A survey of experts helped to finalize the information elements, categorize them, and prepare the final version of the checklists. Based on this, the system requirements were classified into 11 categories, and the training content was classified into 3 training periods. Finally, the design and development of the system was done. This system has admin, physician, and patient user interfaces. The result of usability showed that this system is efficient and there are only a few problems in the feature of helping users to detect and recover from errors.
CONCLUSIONS: It seems necessary to develop a system based on the principles of usability by therapists and rehabilitation specialists to train and monitor the remote rehabilitation process of patients after knee joint replacement at home. And the importance of involving stakeholders in the design and development of remote rehabilitation systems is not hidden from anyone. Kara system has all of the above.
