@entity1 with @entity4531 ( @entity4531 ) complain of motor restlessness, usually occurring while they rest in the evening. Two immobilization tests have been described to assess leg restlessness in these @entity1 . In the first test, the @entity1 sits in bed with his or her legs outstretched while electromyograms are recorded from right and left anterior tibialis muscles for an hour ( @entity1062 [ @entity1062 ]); in the second test, the legs are immobilized in a stretcher (Forced Immobilization Test [FIT]). In the current study, the @entity1062 and the FIT were compared in @entity1 with @entity4531 and normal control subjects matched for age and sex. More leg movements were seen in @entity1 than in controls during immobilization tests, especially the @entity1062 . These movements were periodic, occurring at a frequency of approximately one every 12 seconds. The @entity1062 (index > 40) was found to discriminate between @entity4531 and control subjects better than the FIT (index > 25). @entity1 were also recorded during two consecutive nights to measure periodic leg movements in sleep (PLMS). A @entity1062 index greater than 40 and a PLMS index greater than 11 (highest PLMS index of 2 consecutive nights) were found to discriminate @entity1 with @entity4531 from control subjects with similar power. With each of these two measures, the clinical diagnosis was correctly predicted in 81% of @entity1 and 81% of the control subjects. The @entity1062 has several advantages over the measure of the PLMS index; it does not require an all-night polygraphic recording and can be administered several times a day to measure circadian fluctuation of motor restlessness.
