Polysomnography7
- Studies have found actigraphy to be helpful for sleep research because it tends to be less expensive and cumbersome than polysomnography. (wikipedia.org)
- However, actigraphy cannot be considered as a substitute to polysomnography. (wikipedia.org)
- The main reason for this development is the fact that, while retaining mobility, actigraphy offers reliable results with an accuracy that is close to those of polysomnography (above 90% for estimating total sleep time but dropping to 55% for a 4 - way sleep stage estimation problem). (wikipedia.org)
- A variety of objective and subjective tools have been used to assess sleep-wake rhythms in children and adolescents, including polysomnography (PSG), actigraphy, sleep diary, and parental report questionnaires. (frontiersin.org)
- Simultaneous actigraphy and polysomnography as well as CSF white blood cell (WBC) count, trypanosome presence, and CXCL-10 cytokine levels were performed in 20 HAT patients and nine healthy individuals (controls) using standard procedures. (univr.it)
- Sleep was evaluated with polysomnography, actigraphy, and questionnaires. (scielo.br)
- [ 11 ] Sleep can be monitored by subjective (questionnaires), objective (polysomnography [PSG] or actigraphy), or multimodal ways. (medscape.com)

Detect1
