Development of digital measures for nighttime scratch and sleep using wrist-worn wearable devices

N. Mahadevan, Y. Christakis, et al.

This innovative study delves into the challenges faced by patients with atopic dermatitis, focusing on nighttime scratching and sleep disturbances. Conducted by a team of researchers from Pfizer and the University of Rochester, the research introduces a groundbreaking method utilizing wrist-worn accelerometer data to objectively measure scratching and sleep, demonstrating strong correlations with established sleep measures.

Abstract
Patients with atopic dermatitis experience increased nocturnal pruritus leading to scratching and sleep disturbances. This study developed and validated a method using wrist-worn accelerometer data to continuously measure nighttime scratching and sleep quantity. Heuristic and machine learning algorithms were used to detect sleep intention, sleep-wake states, and scratching episodes. Results showed strong correlations between sensor-derived measures and reference polysomnography and video data, supporting the use of wearables for objective, continuous measurement of nighttime scratching and sleep.
