The purpose of this study is to investigate the count‐characteristics of wrist actigraphy in basic human activities and to discuss the agreement of Sleep‐wake identification between polysomnography (PSG) and wrist actigraphy during nocturnal sleep. There was a distinct distribution of actigraphy counts over the studied activities. The evaluation of Sleep‐wake scoring using the wrist actigraphy agreed 96.9% with the polysomnographic scoring during nocturnal sleep.
