Digital biofeedback systems (DBSs) are used in physical rehabilitation to improve outcomes by engaging and educating patients and have the potential to support patients while doing targeted exercises during home rehabilitation. The components of feedback (mode, content, frequency and timing) can influence motor learning and engagement in various ways. The feedback design used in DBSs for targeted exercise home rehabilitation, as well as the evidence underpinning the feedback and how it is evaluated, is not clearly known. To explore these concepts, we conducted a scoping review where an electronic search of PUBMED, PEDro and ACM digital libraries was conducted from January 2000 to July 2019. The main inclusion criteria included DBSs for targeted exercises, in a home rehabilitation setting, which have been tested on a clinical population. Nineteen papers were reviewed, detailing thirteen different DBSs. Feedback was mainly visual, concurrent and descriptive, frequently providing knowledge of results. Three systems provided clear rationale for the use of feedback. Four studies conducted specific evaluations of the feedback, and seven studies evaluated feedback in a less detailed or indirect manner. Future studies should describe in detail the feedback design in DBSs and consider a robust evaluation of the feedback element of the intervention to determine its efficacy.

用于家庭康复的有针对性的运动数字生物反馈系统的反馈设计：范围界定审查。


数字生物反馈系统（DBS）用于身体康复，通过吸引和教育患者来改善结果，并有可能在家庭康复期间进行有针对性的锻炼时为患者提供支持。反馈的组成部分（模式、内容、频率和时间）可以通过多种方式影响运动学习和参与。 DBS 用于有针对性的家庭运动康复的反馈设计、支持反馈的证据及其评估方式尚不清楚。为了探索这些概念，我们进行了范围界定审查，从 2000 年 1 月到 2019 年 7 月对 PUBMED、PEDro 和 ACM 数字图书馆进行了电子搜索。主要纳入标准包括在家庭康复环境中进行针对性练习的 DBS，这些在临床人群中进行测试。我们审查了 19 篇论文，详细介绍了 13 种不同的 DBS。反馈主要是视觉的、同时的和描述性的，经常提供结果知识。三个系统为反馈的使用提供了明确的理由。四项研究对反馈进行了具体评估，七项研究以不太详细或间接的方式评估了反馈。未来的研究应详细描述 DBS 中的反馈设计，并考虑对干预措施的反馈要素进行稳健评估，以确定其功效。
