Algorithms & Measures


Sleep is the subject of increased clinical research, as both a primary disorder and a symptom of another disease.

Inadequate sleep is common in people with arthritis, atopic dermatitis, Alzheimer’s Disease, Parkinson’s Disease, and many other conditions. Research studies focus on measuring and diagnosing these sleep disorders, as well as the development of new treatments to improve sleep health across a broad range of indications. ActiGraph’s technology solutions provide a low-burden and remote approach to objectively quantify real-world sleep habits and health, often revealing meaningful insights that might not be available with polysomnography or self report data.

Sleep latency (SL); Total sleep time (TST); Wake after sleep onset (WASO); Sleep efficiency (SE; SE = TST/time in bed); Circadian rhythm.
