We tested an actigraph embedded in a portable device, BresoDX, to measure head motion to detect sleep/wake state in 75 patients with sleep apnea (SA) vs simultaneous PSG.

The results show that head actigraphy was 92% accurate in detecting sleep compared to PSG. This indicates very good performance equivalent to wrist actigraphy in detecting sleep status in SA patients.
