actigraphiát

Actigraphy is a non-invasive method used to monitor human rest and activity patterns. It typically involves wearing a small, wristwatch-like device, known as an actigraph, on the wrist or sometimes the ankle. This device contains an accelerometer that detects and records body movements. By analyzing the frequency and intensity of these movements over time, the actigraph can estimate periods of sleep and wakefulness.

The data collected by actigraphs can provide valuable insights into an individual's circadian rhythm and sleep-wake cycle. This technology is commonly employed in research settings to study sleep disorders, evaluate the effectiveness of sleep interventions, and assess activity levels in various populations. It is also increasingly used in clinical practice as a tool to help diagnose and manage conditions such as insomnia, circadian rhythm sleep disorders, and restless legs syndrome.

Actigraphy is considered a more objective measure of sleep and activity compared to subjective self-report methods like sleep diaries. However, it is important to note that actigraphy does not directly measure sleep stages (e.g., REM, deep sleep) and is generally used as an adjunct to other diagnostic methods, such as polysomnography, for a comprehensive sleep assessment. The devices are generally comfortable to wear and allow for continuous monitoring over extended periods, making them suitable for capturing typical daily patterns.
