Don’t use polysomnography to diagnose restless legs syndrome, except rarely when the clinical history is ambiguous and documentation of periodic leg movements is necessary.
|Rationale and Comments:||Restless legs syndrome is a neurologic disorder that can be diagnosed based on a patient’s description of symptoms and additional clinical history. Polysomnography generally does not provide additional information necessary to make the diagnosis. If a patient’s clinical history for RLS is ambiguous, PSG to assess for periodic leg movements may be useful to help confirm an RLS diagnosis.|
