- Researchers performed a broad literature search for the use of actigraphy in the assessment of sleep disorders.
- Actigraphy also may be used to characterize other sleep disorders such as insomnia related to depression as well as hypersomnia.
- Actigraphy appears to be less accurate in estimating total sleep time as the number of apneic or hypopneic episodes increase.
- In ealuating response to therapy, actigraphy has proen to be a useful outcome measure in patients with circadian rhythm disorders and insomnia.
- Among patients with sleep apnea, it is best to use actigraphy to estimate total sleep time only when polysomnography is not aailable.
