Does the low power mode of the actigraph GT3X+ accelerometer influence the device output in sleep research in healthy subjects?
We measured lower limb activity by means two, above each ankle vertically aligned GT3X+ accelerometers in 4 healthy adults during a single night. Triaxial raw data vector magnitude units (VMU) were recorded at 100 Hz, in order to compare two different modes of operation (i.e. low power mode (LPM)on vs. off).
