What does the term "Periodic Limb Movements" (PLMs) refer to?

The term "Periodic Limb Movements" (PLMs) specifically refers to involuntary flexion and extension movements of the legs during sleep. These movements typically occur in episodes that can be repetitive and may disrupt the sleep of the individual. PLMs are often characterized by a specific pattern, where the legs flex at the hip and knee or extend at the ankle, and they can be associated with various sleep disorders, particularly restless legs syndrome and sleep apnea. Recognizing and diagnosing PLMs is crucial in the field of polysomnography, as they can significantly impact sleep quality and overall health. Understanding this condition is vital for sleep technologists and healthcare professionals engaged in sleep studies and treatments.
