To evaluate psychometrics of wearable devices measuring physical activity (PA) in ambulant children with gait abnormalities due to neuromuscular conditions.
We searched PubMed, Embase, PsycINFO, CINAHL, and SPORTDiscus in March 2023.
We included studies if (1) participants were ambulatory children (2-19y) with gait abnormalities, (2) reliability and validity were analyzed, and (3) peer-reviewed studies in the English language and full-text were available. We excluded studies of children with primarily visual conditions, behavioral diagnoses, or primarily cognitive disability. We performed independent screening and inclusion, data extraction, assessment of the data, and grading of results with 2 researchers.
Our report follows Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We assessed methodological quality with Consensus-based Standards for the selection of health measurement instruments. We extracted data on reported reliability, measurement error, and validity. We performed meta-analyses for reliability and validity coefficient values.
Of 6911 studies, we included 26 with 1064 participants for meta-analysis. Results showed that wearables measuring PA in children with abnormal gait have high to very high reliability (intraclass correlation coefficient [ICC]=0.81; 95% confidence interval [CI], 0.74-0.89; =88.57%; ICC=0.99; 95% CI, 0.98-0.99; =71.01%) and moderate to high validity in a standardized setting ( =0.63; 95% CI, 0.36-0.89; =99.97%; =0.68; 95% CI, 0.57-0.79; =98.70%; =0.69; 95% CI, 0.58-0.80; =87.02%). The methodological quality of all studies included in the meta-analysis was moderate.
There was high to very high reliability and moderate to high validity for wearables measuring PA in children with abnormal gait, primarily due to neurological conditions. Clinicians should be aware that several moderating factors can influence an assessment.
评估可穿戴设备在因神经肌肉疾病导致步态异常的门诊儿童中测量身体活动（PA）的心理测量学特性。
我们于2023年3月检索了PubMed、Embase、PsycINFO、CINAHL和SPORTDiscus。
如果符合以下条件，我们纳入研究：（1）参与者为有步态异常的门诊儿童（2至19岁）；（2）分析了可靠性和有效性；（3）有英文同行评审研究且可获取全文。我们排除了主要有视觉问题、行为诊断或主要有认知障碍的儿童的研究。我们由两名研究人员进行独立筛选和纳入、数据提取、数据评估以及结果分级。
我们的报告遵循系统评价和Meta分析的首选报告项目指南。我们使用基于共识的健康测量工具选择标准评估方法学质量。我们提取了关于报告的可靠性、测量误差和有效性的数据。我们对可靠性和有效性系数值进行了Meta分析。
在6911项研究中，我们纳入了26项研究，共1064名参与者进行Meta分析。结果显示，在步态异常儿童中测量PA的可穿戴设备具有高到非常高的可靠性（组内相关系数[ICC]=0.81；95%置信区间[CI]，0.74 - 0.89； =88.57%；ICC=0.99；95% CI，0.98 - 0.99； =71.01%），在标准化环境中具有中等至高的有效性（ =0.63；95% CI，0.36 - 0.89； =99.97%； =0.68；95% CI，0.57 - 0.79； =98.70%； =0.69；95% CI，0.58 - 0.80； =87.02%）。纳入Meta分析的所有研究的方法学质量为中等。
对于测量因神经疾病导致步态异常儿童PA的可穿戴设备，具有高到非常高的可靠性和中等至高的有效性。临床医生应意识到有几个调节因素会影响评估。
