Simulation-Based Evaluation of Methods for Handling Nonwear Time in Accelerometer Studies of Physical Activity [0.03%]
基于模拟的评估加速计运动研究中处理非佩戴时间的方法的效果
Kristopher I Kapphahn,Jorge A Banda,K Farish Haydel et al.
Kristopher I Kapphahn et al.
Accelerometer data are widely used in research to provide objective measurements of physical activity. Frequently, participants may remove accelerometers during their observation period resulting in missing data referred to as nonwear perio...
Convergent validity of time in bed estimates from activPAL and Actiwatch in free-living youth and adults [0.03%]
免费生活青年和成人中来自activpal和actiwatch的床上时间估计的汇聚效度
Paul R Hibbing,Jordan A Carlson,Stacey L Simon et al.
Paul R Hibbing et al.
Actiwatch devices are often used to estimate time in bed (TIB), but recently became commercially unavailable. Thigh-worn activPAL devices could be a viable alternative. We tested convergent validity between activPAL (CREA algorithm) and Act...
CHAP-Adult: A Reliable and Valid Algorithm to Classify Sitting and Measure Sitting Patterns Using Data From Hip-Worn Accelerometers in Adults Aged 35 [0.03%]
CHAP-成人：使用来自髋部佩戴加速度计的数据可靠有效地对坐姿状态进行分类并测量坐着的行为模式的算法研究在35岁及以上的成年人中的应用
John Bellettiere,Supun Nakandala,Fatima Tuz-Zahra et al.
John Bellettiere et al.
Background: Hip-worn accelerometers are commonly used, but data processed using the 100 counts per minute cut point do not accurately measure sitting patterns. We developed and validated a model to accurately classify sit...

Vincent Shieh et al.
Introduction: Instrumented gait mat systems have been regarded as one of the gold standard methods for measuring spatiotemporal gait parameters. However, their portable walkways confine walking to a restricted area and li...
Body-Worn Sensors Are a Valid Alternative to Forceplates for Measuring Balance in Children [0.03%]
身体穿戴式传感器可作为测量儿童平衡的地面反力测力台的有效替代工具
Vincent Shieh,Ashwini Sansare,Minal Jain et al.
Vincent Shieh et al.
Aims: Clinical evaluation of balance has relied on forceplate systems as the gold standard for postural sway measures. Recently, systems based on wireless inertial sensors have been explored, mostly in the adult populatio...
