Figure 2. Examples of actigraphic findings in relation to Rancho Los Amigos scale of cognitive functioning (RLA) scores.

Examples of typical actigraphic findings for RLA ranging from 3 to 5 (left panel), and RLA ranging from 6 to 8 (right panel). Total activity counts for each minute of recording are illustrated by vertical dark lines, on a scale of 0 to 1,000 activity counts. Daytime hours (07:00–22:00 hours) are shown in yellow and nighttime hours (22:00–07:00 hours) in blue. Daily daytime activity ratios (DAR) are indicated at the bottom of each actogram.
