actigraphy
Indications:
1) evaluation of sleep disorders (first line) [2]
- circadian rhythm sleep disorders
- sleep related breathing disorders
- sleep patterns among special populations
- excessive daytime sleepiness [2]
- first line testing [2]
2) determination of response to therapy
3) often replaces polysomnography when
- longitudinal or large scale data sets are needed
- polysomnography is not a cost-efficient option
Procedure:
- involves use of a portable device that measures activity over an extended period of time (1-2 weeks)
- measures movement of a limb & ambient light
Clinical significance:
- it is one component of polysomnography
