Answer

Polysomnography (PSG) may be necessary to quantify periodic leg movements of sleep (PLMS) or to characterize sleep architecture, especially in children and in patients who continue to have significant sleep disturbances despite relief of RLS symptoms with treatment. PSG should also be used in patients with other suspected sleep comorbidities.
