What best describes an important feature of Restless Legs Syndrome?

Restless Legs Syndrome (RLS) is characterized by an uncontrollable urge to move the legs, typically due to uncomfortable sensations. An essential feature of RLS is that symptoms often worsen with inactivity. When individuals are sitting or lying down, they may experience increased discomfort, which necessitates movement to relieve the sensations. This worsening sensation with inactivity is a distinguishing aspect of RLS, setting it apart from other conditions that may involve leg discomfort or movement.

In contrast, episodes of RLS commonly manifest in the evening or nighttime rather than during the daytime, making it more likely for individuals to struggle with sleep rather than being symptomatic during waking hours. RLS is not specifically associated with vivid dreaming, nor do the movements typically occur during REM sleep; rather, the restlessness usually increases during periods of relaxation, highlighting the importance of movement for symptom relief.
