-living scenario. Postural Transition Detection The activPAL3 detected fewer transitions across all transition categories during both scenarios, compared to the video annotation data (Table  5 ). For transitions from sitting/lying to standing and visa-versa, percentage of agreement ranged from 33.13% to 31.63% for

center of gravity can greatly alter balance during different postural transition phases and the reason why STS requires good coordination of muscle activity to achieve postural stability. With age-related reductions in the physical mobility of older adults, decreased motor control ability exerts greater

within a system changing over time, as has been done to probe postural transitions for feet-in-place responses ( Bardy et al., 2002 ), would be beneficial in future studies on stepping. Whether the changes in CM motion and hysteresis-like effect represent switching between two distinct leg movement tasks

standing position, it is difficult to derive thigh and body posture from a hip-worn accelerometer signal. 21 This measurement limitation is important because sedentary behavior dimensions such as sit-to-stand postural transitions and time spent standing may influence metabolic biomarkers and health

-day week (5 school days and 2 weekend days) was measured with activPAL™ accelerometers (activPAL3C™ and activPAL™ micro; PAL Technologies, Glasgow, United Kingdom). The activPAL™ comprises a tri-axial capacitive accelerometer, which can analyze different postures (sitting/lying and upright), postural

activPAL3C ™ is 55 mm × 35 mm × 7 mm in size and 15 g in weight, whereas the activPAL ™ micromonitor is 45 mm × 25 mm × 5 mm in size and 8 g in weight. Both comprise a triaxial capacitive accelerometer, which can analyze different postures (sitting/lying and upright), postural transitions, step count and
