LAUSR

Although restless leg syndrome (RLS) is often an inherited disorder, this symptom complex can also arise in association with various secondary causes, such as cerebral stroke, renal failure, lumbosacral radiculopathy, and peripheral neuropathy. Clinical features of acquired forms of RLS, including those of sporadic cases, can be indistinguishable from manifestations of RLS occurring as a familial disorder. Similarly, unilateral presentations of RLS generally do not differ in symptomatology from those cases with bilateral involvement. Since the neurological substrate underlying RLS remains a mystery, acquired instances of this syndrome offer the potential for useful insights. In this report, a case is described in which unilateral RLS developed and persisted after ipsilateral leg trauma.
