Sleep is an essential part of health, well-being and recovery from illness and injury. A disrupted sleep pattern can result in poor recovery, increased pain weight gain and fatigue.
Monitoring sleep can be performed through simple or complex approaches, and the methods used are influenced by the clinical scenario and the suspected conditions. For example, when sleep apnoea is suspected monitoring with respiratory equipment in a sleep laboratory or at home is required. When the question is related to abnormalities in the sleep rhythm, simple monitors worn for a few days and nights can be used as the initial approach. The simplest of these are activity monitors, as available in retail stores, but more sophisticated monitors can examine heart rate variability and activity patterns to allow greater accuracy and sensitivity of assessment.
