To test the accuracy of the IDEEA monitor in the detection of postures (lie, sit, recline, stand, and lean) and active gaits (walk, ascend/descend stairs), each study participant went through a series of activities wearing the IDEEA monitor and the readings were compared to that of observations by the study coordinator.
