What tool is commonly used to monitor limb movements during sleep?

The leg movement monitor or EMG electrodes are specifically designed to assess and record limb movements during sleep. This is crucial for diagnosing conditions such as periodic limb movement disorder (PLMD) and restless legs syndrome (RLS). EMG (electromyography) electrodes measure the electrical activity of muscles, which provides valuable information about involuntary movements that can occur during sleep cycles.

In contrast, the EEG monitor primarily focuses on brain wave activity, providing insights into sleep stages and neurological conditions rather than limb movements. Continuous glucose monitors are used to track blood sugar levels in individuals with diabetes and are not related to sleep monitoring. Heart rate monitors track cardiovascular activity but do not capture data pertaining to limb movements. Thus, the leg movement monitor or EMG electrodes are the most appropriate tools for monitoring limb movements during sleep.
