Figure 2

Frequency distributions of subjects meeting (A and B) mean m-SIT-DS and (C and D) mean PLMW cutoff scores during m-SIT-3 in patients with RLS (A and C) and healthy controls (B and D). Out of the scores shown, cutoff scores of > 2 for mean m-SIT-DS and ≥ 10 for mean PLMW/h were chosen. Black bars represent the final 4-SIT combination recommended in this article. As shown in Figure 2B, none of the controls met these cutoff scores in a single SIT. DS, disturbance scale; PLMW, periodic limb movement during wakefulness; m-SIT, Multiple Suggested Immobilization Test.
