- Objectives: We aimed to describe the sensory topography of restless legs syndrome (RLS) sensory symptoms and to identify the relationship between topography and clinical variables. Methods: Eighty adult patients with drug-naive RLS who had symptoms for more than 1 year were consecutively recruited. During face-to-face interviews using a structured paper and pencil questionnaire with all participants, we obtained clinical information and also marked the topography of RLS sensory symptoms on a specified body template, all of which were subsequently inputted into our in-house software. The RLS sensory topography patterns were classified according to localization, lateralization, and symmetry. We investigated if these sensory topography patterns differed according to various clinical variables. Results: The lower extremities only (LE) were the most common location (72.5%), and 76.3% of participants exhibited symmetric sensory topography. Late-onset RLS showed more asymmetric sensory distribution compared with early-onset RLS (P = .024). Patients whose sensory symptoms involved the lower extremities in addition to other body parts (LE-PLUS) showed more severe RLS compared with those involving the LE (P = .037). Conclusion: RLS sensory symptoms typically were symmetrically located in the lower extremities. LE-PLUS or an asymmetric distribution more often occurred in patients with more severe RLS symptoms or late-onset RLS.
