Unilateral Poststroke Periodic Limb Movements: A Case Series.

Periodic limb movements (PLM) and restless leg syndrome (RLS) are involuntary common sleep-related movements which often hamper sleep onset; they are mostly idiopathic and bilateral but are seldom described secondary after a stroke. These cases are rare, often unilateral, and because of the usually transitory duration of symptoms, often under-recognized. When a treatment is required, it can be tricky and the drug choice not foregone.
