Table 1.
Median values of ENMO, VMC and AI0 statistics derived for τ = 5-s length intervals of data collected from the left wrist during writing, washing dishes, vacuuming, getting dressed and walking, for all 49 individuals. Results are obtained for original sampling frequency fs = 80Hz (3rd column) and simulated sampling frequencies fs = 40, 20, 10 Hz (4–6th columns).
