More than 3,000 adult participants in NHANES wore an actigraph
for 7 days to measure physical activity.
GT3X+ accelerometer (ActiGraph
LLC, Pensacola, United States) was used to assess step-defined physical activity.
Then, we provided participants with a GT3X+ Actigraph
accelerometer along with an oral and written explanation of the appropriate wearing and handling of the device.
2010) Associations between obstructive sleep apnea, metabolic syndrome, and sleep duration, as measured with an actigraph
, in an urban male working population in Japan.
On each data collection day, participants wore an ActiGraph
GT3X+ accelerometer (Shalimar, Florida) on their right hip for the duration of each PA class.
They are also equipped with actigraph
watches to monitor their sleep-wake patterns.
The study included 31 older adults (ages 55-82) who wore a small device called an ActiGraph
, which recorded information including how many steps each took, how vigorous the steps were and how much time it involved, Medical Xpress reported.

The diagnostic sleep apnea devices segment is further segmented into polysomnography (PSG) devices, respiratory polygraphs, pulse oximeters and actigraph
systems and the treatment sleep apnea devices are further sub segmented into positive airway pressure (PAP) devices, facial interfaces, adaptive servo ventilation (ASV), airway clearance systems, oxygen concentrators, oral appliances and accessories.
Changes in sleep-wake cycle during the period from late pregnancy to puerperium identified through the wrist actigraph
and sleep logs.
