Suzuki K, Suzuki S, Miyamoto M, et al. - In this study, 89 individuals diagnosed with restless legs syndrome (RLS) or RLS variants according to established criteria, with the exclusion of those with augmentation, were involved in order to examine the distribution of sensory symptoms and clinical associations in individuals with RLS and its variants. Eighty-three had RLS and six had RLS variants. Among the individuals with RLS and RLS variants, 33 individuals reported restlessness involving other body parts ie, the most common region were arms (16.9%), followed by the back (10.1%), abdomen (6.7%), and buttocks (4.5%). No between-group variations in clinical features was seen, except for the level of sleep disturbances being greater in individuals with RLS variants (n = 6) vs with RLS (n = 83). No notable variation was regarded in clinical features including RLS severity and treatment among individuals with RLS only (n = 57) and with RLS with other body part involvement (n = 26). Between the onset of symptoms in the legs and other body parts, no correlation was seen, however, the international RLS rating scale scores for legs and other body parts were considerably associated with one another. Thus, it should be understood that in every individual, RLS could involve not only legs but also other body parts to differing degrees.
