Subjective sleep quality and suggested immobilization test in restless leg syndrome and periodic limb movement disorder

The severity of restless leg syndrome (RLS) and/or periodic limb movement disorder (PLMD) was investigated by using a suggested immobilization test (SIT) and by measuring the influence of these disorders on the subjective sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI).

Description
Summary:The severity of restless leg syndrome (RLS) and/or periodic limb movement disorder (PLMD) was investigated by using a suggested immobilization test (SIT) and by measuring the influence of these disorders on the subjective sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI). Patients with RLS and those with both RLS and PLMD showed remarkably high values for PSQI and SIT, whereas patients with PLMD only showed normal values for PSQI. These findings suggest that there is only a small pathological significance for periodic limb movements, and demonstrate the efficacy of SIT and PSQI for evaluating the severity of these disorders.
