Other studies include the following:

  • Needle electromyography and nerve conduction studies: Should be considered if polyneuropathy or radiculopathy is suspected on clinical grounds, even if the results of the neurologic examination are apparently normal [5]

  • Polysomnography: May be necessary to quantify 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

See Workup for more detail.
