To investigate the validity and reliability of accelerometers to detect lying, sitting and standing postures or purposeful activity in hospitalized adults recovering from acute or critical illness.
CINAHL, MEDLINE, EMBASE, AMED, Cochrane Library, PEDro, PsycINFO and SPORTDiscuss were searched from inception to June 2017. Professional networks and reference lists of relevant articles were also searched. The main selection criteria were hospitalized adults with acute or critical illness and studies investigating the validity or reliability of accelerometers to identify body position or purposeful activity.
Two authors individually assessed study eligibility and independently undertook methodological quality assessment and data extraction from selected articles. A narrative synthesis of the data was undertaken.
Fifteen studies, collectively enrolling 385 hospitalized participants, were identified. Populations included stroke, the elderly, acute exacerbation of chronic respiratory disease, abdominal surgery and those recovering from critical illness. Correlations of r = 0.36 to 0.98 and levels of agreement of κ = 0.28 to 0.98 were reported for identification of lying, sitting or standing postures. Correlations of r = 0.4 to 0.8 with general activity were found, with r = 0.94 and 0.96 reported for step count. The reliability of accelerometry measurement was investigated in one study evaluating step count quantification (intraclass correlation coefficient (ICC) = 0.99, 95% confidence interval (CI) = 0.99-1.00).
The validity of accelerometers to determine lying, sitting and standing postures or quantify purposeful activity within hospitalized acute or critically ill populations is variable. The reliability of accelerometry measurement within this setting remains largely unexplored.
调查加速度计检测住院成人急性或危重病康复期间的躺、坐和站立姿势或有目的活动的有效性和可靠性。
从创建到 2017 年 6 月，CINAHL、MEDLINE、EMBASE、AMED、Cochrane 图书馆、PEDro、PsycINFO 和 SPORTDiscuss 进行了检索。还搜索了相关文章的专业网络和参考文献列表。主要选择标准是患有急性或危重病的住院成人以及研究加速度计识别身体姿势或有目的活动的有效性或可靠性的研究。
两名作者分别评估研究的合格性，并独立进行方法学质量评估和从选定文章中提取数据。对数据进行了叙述性综合。
确定了 15 项研究，共纳入 385 名住院患者。研究人群包括中风、老年人、慢性呼吸疾病急性加重、腹部手术和危重病康复患者。报告了对躺、坐或站立姿势的识别的 r = 0.36 至 0.98 的相关性和 κ = 0.28 至 0.98 的一致性水平。发现与一般活动相关的 r = 0.4 至 0.8，步计数报告 r = 0.94 和 0.96。一项评估步数量化的研究（组内相关系数 (ICC) = 0.99，95%置信区间 (CI) = 0.99-1.00）调查了加速度计测量的可靠性。
加速度计检测住院急性或危重病患者的躺、坐和站立姿势或量化有目的活动的有效性是可变的。在这种情况下，加速度计测量的可靠性在很大程度上仍未得到探索。
