Abstract

Purpose

To evaluate vertical acceleration, vector magnitude, non-wear time, valid day classifications, and valid period classifications in the data processing phase when using the ActiGraph GT3X accelerometer in non-ambulant children and adolescents with cerebral palsy (CP).

Material and Methods

Accelerometer data retrieved from 33 non-ambulant children and adolescents (4–17 years) with CP were analysed. Comparisons of (i) vertical acceleration versus vector magnitude, (ii) two different non-wear times, (iii) three different settings to classify a day as valid and (iv) two different settings to classify a period as valid were made.

Results and Conclusions

Vector magnitude and a non-wear time of at least 90 consecutive minutes statistically significantly increased minutes recorded per day, especially for sedentary time. There was a statistically significant difference in numbers of valid days depending on time criteria set to determine a valid day, whereas there was no statistically significant difference in valid periods using 3 compared to 4 days. This study suggests using the pre-settings in ActiLife; vector magnitude, non-wear time of 90 consecutive minutes, 500 min recorded per day with periods of at least 3 valid days when assessing physical activity objectively by the ActiGraph GT3X accelerometer in non-ambulant children and adolescents with CP.

评估使用ActiGraph GT3X加速度计治疗脑瘫儿童和青少年时的数据处理

目的评价ActiGraph GT3X加速度计在非活动儿童和青少年脑瘫(CP)患者数据处理阶段的垂直加速度、矢量大小、非磨损时间、有效日分类和有效期分类。材料和方法对33例非活动CP儿童和青少年(4-17岁)的加速度计数据进行分析。比较了(i)垂直加速度与矢量量级，(ii)两种不同的非磨损时间，(iii)三种不同的设置将一天分类为有效，(iv)两种不同的设置将一个时间段分类为有效。结果和结论矢量大小和连续至少90分钟的非磨损时间在统计上显著增加了每天记录的分钟数，特别是久坐时间。根据确定有效天数的时间标准，有效天数的数量在统计学上有显著差异，而使用3天和4天的有效天数在统计学上没有显著差异。本研究建议使用ActiLife中的预设;当使用ActiGraph GT3X加速度计客观评估患有CP的非活动儿童和青少年的身体活动时，矢量大小，非磨损时间为连续90分钟，每天记录500分钟，持续至少3天。

期刊介绍： Clinical Physiology and Functional Imaging publishes reports on clinical and experimental research pertinent to human physiology in health and disease. The scope of the Journal is very broad, covering all aspects of the regulatory system in the cardiovascular, renal and pulmonary systems with special emphasis on methodological aspects. The focus for the journal is, however, work that has potential clinical relevance. The Journal also features review articles on recent front-line research within these fields of interest. Covered by the major abstracting services including Current Contents and Science Citation Index, Clinical Physiology and Functional Imaging plays an important role in providing effective and productive communication among clinical physiologists world-wide.
