(a) The mean hourly trend in DVAV signals detected by our software over 24 hours across the entire dataset recorded on the central accelerometer; (b) on the peripheral accelerometer; (c) The mean hourly trend calculated over 30 dates and moved 1 day across the central accelerometer dataset; and (d) across the peripheral accelerometer dataset. This graph is obtained over the vibrational dataset shown in Fig. 4. The vertical bars indicate +/− 1 standard error (SE).
